A program for finding similar images. The best software for finding and removing duplicates

In this material we will talk about tools for identifying duplicate photos. In particular, today our review will include six programs for finding duplicate photos on a computer under Windows control. We will compare and choose the best and fastest among them.

There may be several reasons for the demand for such programs: on the one hand, your collection could have grown so large that duplicates are already taking up a lot of space. On the other hand, even more often you just need a tool that will find the same or similar photos, saving you the trouble of viewing these images yourself.

In our selection there was room for six interesting programs, four of which are distributed free of charge. Next, we will talk about each of them and help you quickly navigate the interface if you decide to try these applications.

And in the final part you will find a small comparison of all programs, in which we will see how they cope with the search identical pictures with their slight modification, and we will also check how well the programs can cope with a large set of photographs weighing several gigabytes.

Image Comparer

The first program in our review, looking for duplicates photo called Image Comparer. Her strengths: good functionality and interface translated into Russian, including detailed help information.

Now about the disadvantages. First, the program is not free. However, the cost of a license is a humane 350 rubles (although for some reason the number on the website is 500). In addition, you can use Image Comparer for free for the first 30 days.

Second negative point lies in slight confusion that can confuse inexperienced user. For example, in order to search within one folder (which may contain others), you need to click on the “create gallery” button and select the desired directory in which to scan.

Next, you will immediately be prompted to give a name and save the file of the created gallery to any convenient place(this file will be needed by the program itself). Once this is done, a list of all the images in the specified folder and its subfolders will open in front of you in the form of a list or thumbnails:

Buttons marked with arrows start searching for duplicates. The first button is a search within one gallery (the folder you selected), the second button a little to the right is within several galleries. We went with the first option.

Next, the program suggested creating another service file in which the results will be saved for further convenient access to them. Actually, creating a file for the gallery and this file with search results can be a little confusing for an inexperienced user. However, then everything is already simple. The found duplicates will appear in front of you:

They can be viewed in the form of thumbnails, or by clicking on the “image pairs” tab, go to the view where the photos will be compared with each other:

The center slider allows you to adjust the threshold of image similarity. 100% - and you will only be left with a list of perfectly similar, identical pictures. Lower values ​​will only show similar photos.

In the settings you can see a huge list of formats from basic JPG and PNG to more exotic ones that the program works with. Formats can be added and excluded from the search. You can also configure the accounting of reflected and inverted images.

VisiPics

The next program is VisiPics. Unlike the Image Comparer discussed above, VisiPics is free application, also specializing in photo duplicates. Alas, there is no localization into Russian here, but you definitely shouldn’t be upset about this: everything is very simple and extremely clear.

Using the side navigation bar (we've framed it), select the desired directory. Next, click the arrow with the “+” sign to add this folder to the list that will be searched. If you wish, you can select several more folders in the same way. Finally, as a third step, click the Play button to start the process of finding duplicates.

To the right of it is a special slider where you can adjust the level of “attention” of the program. With the default baseline, VisiPics found only two groups of duplicates for us, one of which consisted of three images, and the other of the two:

These are the images that the program considers to be almost identical duplicates. However, if you lower the slider to the Loose level, then there will be images that are simply similar to each other. In our case, when installing Loose instead of Basic, the application found four more (5 in the final test below) groups of duplicates, and added one more picture to one of the two already found:

The program has relatively few additional options. Here you can configure search in subfolders (it is enabled by default), display hidden folders, accounting for photographs rotated 90 degrees. On the loader tab, you can ask VisiPics to ignore small files or, conversely, pictures that are too large high resolution. The latter is important for speed.

Awesome Duplicate Photo Finder

If you are looking for the utmost a simple program for a high-quality search for duplicate photos and images that would be easy to understand, then pay attention to Awesome Duplicate Photo Finder. The interface is in English, but it is so simple that anyone can understand it.

Using the “+” button, specify the directory or several directories you need to search, then click Start Search and the search begins for them. The Scan Subdirectories option is enabled by default and is responsible for searching subfolders. The program copes with its tasks, finding both very similar:

And here are pictures that are slightly more different from each other:

In the program settings, you can set the match to 100% if you only need absolutely identical photos.

As you can see, there are few settings themselves. Perhaps the saddest thing is that the program works with only five main formats: BMP, JPG, PNG, GIF and TIFF. Moreover, the latter is not taken into account by default.

There are also options to ensure duplicates are deleted directly to the Trash and disable pop-up confirmation. The program can also update itself automatically.

Similar Images Finder

The Similar Images Finder application greets us with an unkind message in English that we need to pay $34 for it. However, the program is ready to work for free for 30 days. Next, a window appears asking you to select directories to search for duplicates:

From it we learn that Similar Images Finder supports 29 image formats, and the user can select specific formats to search or exclude unnecessary ones. In the list, among other things, you can see ico and wbmp.

When you click Next you will start searching for duplicates, and when it is finished, click Next again to see additional settings. By adjusting them, you can more carefully customize what appears in the results list. Finally, by clicking Next for the third time, you will finally see the result itself:

You can move to the next found picture by clicking the miniature arrow in the upper right corner. The entire list of found duplicates opens by clicking on big button at the top with the addresses of the current files.

In turn, clicking the Next button at the bottom will lead to the final stage of work. There the program will display a list of what, in its opinion, are definitely duplicates and offer to delete them. In the screenshot above, Similar Images Finder coped with an image where a watermark was added and the histogram contrast was changed.

Distinguishing between the pictures, the program calculated at 5.5%. Moreover, in another example, where we added a strong blur effect to the second picture, the differences according to the application version for some reason amounted to only 1.2%:

Alas, the program, while finding real duplicates, by default also shows many images that are completely different from each other, as if they have something in common:

Duplicate Remover Free

Duplicate Remover Free is the only program in our review that is not focused specifically on duplicate photos, but on finding duplicates in general. As practice shows, such universal solutions do not perform very well in tasks related to some narrower area.

However, today we are giving one such program a chance. As the word Free suggests, it is distributed free of charge. The second advantage of the application is the Russian language, and the third is its relative modernity compared to other programs in this collection, many of which, unfortunately, have not been updated for many years.

You should click on the “add directory” button and select the desired folders. By default, the program did not find anything for us in the given directory, however, when at the top instead of “exact duplicates” we selected the “similar images” item, four groups of duplicates were immediately found, one of which consisted of three files at once:

The application has very few additional features. In particular, you can exclude files from the search before and after a certain size.

• Distribution: free.

AntiDupl

The final participant in our review is AntiDupl program may appeal to you for several reasons. First of all, it's free. Secondly, it has a Russian interface. The latter, however, is not obvious. To enable Russian, open the View menu and in Language section select the appropriate item:

Unlike others, this program is not installed, but is located in a self-extracting archive that extracts it along with necessary files in a separate folder.

To prepare the search for duplicates, click on the button labeled Open and add the necessary directories in the window that appears:

Next, you can click OK, and then activate the green “start search” button on the toolbar. Using a basic algorithm, the program found several groups of duplicates for us:

On the “search” tab you can find out that AntiDupl supports 13 formats, including, in addition to traditional JPG/PNG, ICON, PSD and EXIF. Of course, you can choose formats. The options also include checking for defects, blockiness and blurriness, and in the last two cases you can set a threshold. It is possible to search in hidden and system directories.

• Distribution: free.

When searching for duplicates, some users are interested in 100% matching in order to get rid of duplicates in their collection. However, the task often arises of finding exactly similar pictures.

And here huge space for possible differences. This one may be different formats, resolutions, cropped versions of the same image, adding frames and watermarks, changed colors and captions on pictures.

We tried to take into account most of these factors and, after all the testing, we ended up creating a small set with more than six dozen pictures. In them we created nine groups of duplicates. Let’s be honest, our experience certainly doesn’t claim to be the ultimate truth, but it was interesting to try. The results are as follows:

• Duplicate Remover Free: found only 3 groups of duplicates;
• Similar Images Finder: found 4 groups, but inconvenient interface, a lot of false results and at the same time the paid application greatly spoiled the overall impression;
• AntiDupl found 3 types of duplicates by default, installing the SSIM algorithm increased the search result to 5 groups;
• VisiPics at basic level the search found only 2 groups of duplicates, but setting the slider to the Loose level allowed us to find 7 groups;
• Awesome Duplicate Photo Finder found 7 groups of duplicates;
• Image Comparer was also able to detect 7 groups.

At the same time, Image Comparer was able to find images that Awesome Duplicate Photo Finder and VisiPics missed, and they, in turn, filled in the gaps of Image Comparer.

Determining the fastest program for finding duplicate photos

At the same time, the quality of the program also depends on its speed. 60+ pictures is, of course, not something that users can work with. So we did another test. This time for speed. To do this, we took a selection of 4450 of the most different images, the total weight of which exceeded 2.1 GB.

Unfortunately, two programs from this review did not take any place in the test. As it turns out, Similar Images Finder, which costs $34, free version ready to process no more than 200 images at a time.

In turn, a universal search engine Duplicate Remover Free, faced with a catalog of serious size, worked intensively for more than five minutes, and then completely froze. The remaining programs showed the following times:

• AntiDupl: 0:39;
• Image Comparer: 1:02 (35 seconds to create gallery and 27 to search);
• VisiPics: 2:37;
• Awesome Duplicate Photo Finder: 3:17.

As a result, Image Comparer and AntiDupl clearly took the lead in the speed test. It took them about or, in the case of AntiDupl, less than a minute to process our archive.

Conclusion

Let's summarize. If you need to find not identical, but rather similar photographs that differ, for example, in a signature or watermark, then Image Comparer, Awesome Duplicate Photo Finder and VisiPics in Loose mode will cope with this task better than others.

In terms of processing speed for a large collection of images, AntiDupl and Image Comparer are the undisputed leaders.

Finally, in terms of interface convenience, we liked Image Comparer and VisiPics, which immediately allow you to visually evaluate all groups of duplicates. In turn, for the clarity of comparing the characteristics of individual duplicates, we will also note AntiDupl.

Surely you have a large database of photographs. Has it ever happened that you are looking through photographs from this database and you get the feeling that some photos are repeated? Manually search for duplicate photos- long, painful and stupid. I agree with those who say that this is simply a useless exercise, because photographs do not take up so much space on your hard drive, but having well organized catalog of photos I still want to. Yes, and this article would not exist if it did not exist software method find duplicate pictures, so it won’t be difficult for you to do this!

To find duplicate photos, you can use the program AntiDupl.NET. The program is absolutely free, supports the main graphic formats: JPEG, GIF, TIFF, BMP, PNG, EMF, WMF, EXIF ​​and ICON, and has a Russian interface. And in fact, it perfectly performs its main function, searching for duplicates.

From words to deeds. By downloading from the link above, latest version programs AntiDupl.NET, you will receive a self-extracting archive on your computer. By double-clicking on it, you will see the following window, where we will be asked to select a location to unpack the files. Unpack directly to your desktop.

As a result, a folder with a program ready for use will appear in the location you specified. Without thinking for a long time, we launch it. Initially, everything we have there is on English. To see your native Russian language, do the following: Click View - Language - Russian.

In Options, you can add a checkbox: Search for rotated and mirrored duplicates - since often some identical photographs turn out to be simply upside down.

Next, select the folder in which the photos are located and in which there are supposedly duplicates. To do this: Click on the folder icon - the Paths window appears - click add a directory - select the desired folder- click OK. If you need to search not in one, but in several folders, we perform this operation again.

To start the search, click on the green play icon.

As a result, the program will display a list of duplicate pictures. Next, you can either delete both or one of the duplicates.

If you set the options to Consider image size and Consider image type, then the program will find duplicates of only one size and only in one extension, respectively. I would not recommend checking these boxes, since you often come across the same pictures, only of different sizes.

AntiDupl.NET 2.2.4.528 RUS FREE

As a rule, modern computer users there are large collections of images in various formats. And the larger these collections, the more likely they are to contain large number duplicates. The user's natural desire is to get rid of them. However, if the collection is large enough, then doing this manually is a very tedious and unproductive task. Program AntiDupl.NET will help you automate this process. It is capable of finding and displaying duplicate images in the main graphic formats: JPEG, GIF, TIFF, BMP, PNG, EMF, WMF, EXIF ​​and ICON. The comparison is made based on the contents of the files, so the program can find not only completely identical, but also similar images. In addition, the program can find images with certain types of defects. AntiDupl.NET program is free, quite easy to use, has high speed and accuracy of operation, supports Russian interface.

Hello Friends! In this article we will figure out how to implement find duplicate files on our computers. I admit, I don’t have such a problem. Usually, my computer has three partitions. The first system partition is from 50 to 100 GB, the second is for documents from 100 to 200 GB, and the third partition is for everything else. I have one folder for photos, one for music, and so on. Everything is transparent. The parents' computer is another matter. The hard drive is divided into three parts there. On the 3rd section there are two or three folders with photos + in each folder there are a bunch of subfolders. A photo folder was also subsequently formed on drive D. It’s hard to go through everything manually, and here programs for finding duplicate files will help us.

I don't want to install separate program for some function since there are many functions (for example, defragmentation or the same search for the same files). Accordingly, many programs will have to be installed on the computer. My position is the following. The less you install, the more reliable and stable your computer works.

There are solutions. Find a program that is practically necessary for computer maintenance (that is, it will most likely be installed) and that would be able to search for duplicate files. It didn't take long to search. This is the already familiar and proven CCleaner from Piriform. Starting from version 4, CCleaner was added this function and below we will see how it works.

Download the program from the official website

We install.

When you launch it for the first time, the window below will appear. If you select Yes, then when cleaning the computer by default, authorization on the above mail services may not be lost. Click Yes

Go to the Service tab on the left

Click on the Search Files button

To search identical files All that remains is to specify the necessary settings

There are not many settings and they are divided into three groups:

• Coincidence
• Pass
• Where to look and places to exclude

Let's look at each group in more detail.

Coincidence

You can search for duplicate files by Name, Size, and Modified Date. You can also combine these criteria by checking more than one box. When organizing photos on my parents' computer, the first thing I do is search for a match by Name. Most likely there will be a bunch of files saved in different places. Then, it will be interesting to search for a match by Size. Since the photo can be renamed, but the size should not change.

How to effectively use the search for duplicates with the Changed checkbox enabled has not yet occurred to me. If you have options, please write in the comments. Perhaps if you took and added something to the photo without changing the name. But, in this case, with great probability, the size will change.

Pass

Which files should be skipped when searching for duplicates. The following options are possible here:

• Bytes with size 0
• Read-only files
• Size less than x MB
• System files
• Hidden files

Where to look and places to exclude

Here, using the Add button on the Inclusions tab, you specify where to look for duplicate files. On the Exceptions tab, add places on your hard drive, flash drive, or external hard drive where you do not want to search.

In principle, everything is simple. To reset the settings, press the corresponding button.

When the filter is configured, click Find.

Sorting duplicate file search results

The result is an easy-to-view table with search results. Moreover, the table is formed immediately when any duplicate is detected.

Suspected duplicates are separated among themselves. The only thing I would like to see in this table is sorting by clicking on a column.

When you click on a file right click mouse appears context menu, which allows you to conveniently sort search results. This is especially true if there are a lot of results.

The Exclude item allows you to remove all files from the folder you select. For example C:\Program Files. The Limit item will leave only files from the folder you select in the search results. The Select duplicates option allows you to select all files located in the folder you select. The remaining points seem to be clear.

The Open folder option is very useful. Using it, you can quickly go in and see where the file is located and whether there are any identical files there that were not included in the results table or were eliminated by sorting.

All that remains is to figure out which of the files should be left and the rest deleted using the button at the bottom right.

Conclusion

This is how I’m going to look for duplicate files on my and other computers using good old CCleaner. For my purposes, the program's functionality is sufficient. If you need more, then DupKiller is worth a look. This free program, you can read about it and download it from the official website http://dupkiller.com/index_en.html. DupKiller has much more ample opportunities configure the search. It also includes viewing graphic files and listening to audio. An interesting possibility is to not exact match files, but up to a certain level (percentage).

Thanks for sharing the article on social networks. All the best to you!

Quite often on the computer there are identical images- isn't it? And the more folders with pictures you have, the more likely it is that they contain large number duplicates. This is not critical, but it still takes up space. You will be surprised how much disk space will be freed up if you check and delete all duplicate pictures. This is exactly what we will do in our article today. As a rule, we copy from a camera, phone, tablet, etc. entire folders with photographs and we rarely delete copies even if we notice them. Why? Yes, because it's troublesome. Let's see how we can automate the process of finding identical images and deleting them.

Why can't this be done in manual mode? It is possible, but doing it manually is a very labor-intensive and tedious task. And if you have thousands of photos... it’s also an unproductive activity. It’s better to drink a cup of coffee while the program is running than to strain your brain and think “did I see this photo or not - is it a copy?” Yes, and this is almost impossible. (looking ahead, I’ll say that after scanning the program on my computer, the program found 11,934 identical pictures!!!) In my opinion, it’s better to let the “hardware work”... If you are of the same opinion, then look below detailed instructions how to find and delete identical pictures.

There are several programs that can search for duplicate .

AntiDupl.NET
DuplicateFinder
DuplicateFileDetector
DuplicateCleaner
ImageDupeless
ImageComparer
Duplicate File Remover

Many programs are great at working with various files and with different tasks.

But we will consider only one program - which can cope with the task as well as possible. Why this particular program? AntiDupl.NET is a free program with very powerful functionality. It allows you to do search for similar or completely identical images in all major graphic formats such as JPEG, GIF, TIFF, BMP, PNG, etc. It is worth noting that the program analyzes the content itself graphic files, which allows you to find not only completely identical, but also similar images. The program supports the Russian interface, it is possible flexible management Using search parameters and you can also determine some types of defects in images. And at the same time, the program is quite clear and I am sure that you will not have any difficulties.

Let's see an example of searching and deleting identical images

Open the program and specify the interface language

And add a directory that will take into account all the pictures in all internal folders. Or any specific folder at your discretion.

You can also configure search options (if necessary). Then press " Start Search".

Let's be patient for a few minutes.

Next, the program will show all “pairs” of identical pictures in the result window and you can start deleting unnecessary copies of your photos. There are two options - delete the first or second. You can look in the viewing windows and determine which photo you want to delete. If you want to delete, for example, all the first pictures, then you need to press the key combination Ctrl + A and press in top panel button " Remove the first pictures in the selected results". After which all the first pictures will go to the trash. After removing all the duplicates, my computer now has about 4.6Gb more space. I hope this article will help you get rid of unnecessary copies. Good luck!
