Weight loss program pdf. How to reduce the size of a pdf, detailed instructions

What You'll Be Creating

PDF format is a common format for creating digital documents and commercial materials of good quality, ranging from professional tasks to an invitation for mom to Christmas dinner.

While design elements make your document attractive, they also inflate it like a balloon, making it very difficult to transfer and download. Moreover, conventional compression tools create copies with blurry images, which reduces the quality of your pdf document.

In this tutorial, I'll show you how to reduce the size of a large PDF file on any computer without compromising image quality, so you can send high-quality documents without worrying about people receiving a file with blurry images.

For Mac: Using Quartz Filters

The Preview app built into OS X is designed to perform basic operations with PDF files, from viewing, annotation, to compression. To compress PDF, just click File > Export...>Quartz Filter (File → Export… → Quartz Filter) and select Reduce size (Reduce file size).

The problem with Preview's built-in compressor is that your images lose a lot of quality, causing them to appear blurry and sometimes unreadable in your PDF file.

The solution is to use custom quartz filters, which provide a balanced option by reducing file size while maintaining image quality throughout the document.

In this tutorial we will install and use Apple quartz filters from Jerome Colas to reduce a 25 MB PDF file to a more manageable size. You can also download the filter from this Github page.

Step 1: Place the quartz filters in the ~/Library directory.

The first step is to install Apple quartz filters on your computer, in the Filters folder in the system Library folder.

To do this, download quartz filters to your desktop and unpack the archive. Launch Finder and use keyboard shortcuts CMD+SHIFT+G to bring up the drop-down menu Go to folder. Press enter to go to the Library directory.

Once you are in the Filters folder, paste the quartz filters into it. If you don't have a Filters folder, create a new directory and name it "Filters".

Clue: Some people prefer to have these filters only available for their account. To do this, you need to create a Filters folder inside the user's Library folder. To do this, click CMD+SHIFT+G, and type the following:

/Users/ /Library

and press Enter. If the Filters folder is not in this directory, create it.

Step 2: Launch Automator and Create an Automator Application

The next step is to create an Automator application that will compress any PDF file using the filters we just installed.

Launch Automator and create a new document. Click on Application and then on the blue button Choose to create a process.

On the left side is the Automator library. Use the search field to find Apply Quartz Filter to PDF Documents, which you will need to drag to the right side of the window to create a process.

A message will appear in a drop-down window asking you if you would like to add to processes Copy Finder Items(Copy Finder). I strongly recommend that you do this because it will save you from the problem of finding the source file in case the compression result does not suit you.

The final step is to select the quartz filter that you will use to compress the PDF file. If you installed the quartz filter I recommended in Step 1, you should see it listed when you click the Filter drop-down menu. Once you select a filter, give the application a name and save it to your desktop.

Step 3: Upload your PDF file to the Automator Created Application

From now on, file compression becomes a very simple task. To use the Automator app, simply drag the icon of your PDF file and drop it onto the app icon. It will generate a compressed copy of your file. The size will depend on the quartz filter you selected when creating the application in Automator.

For my 25 MB PDF file, I chose the 150 dpi filter, which comes as a standard option for almost all files. The compressed file was about 3 MB, and the image quality was quite acceptable, including small pictures.

You can change the quartz filter to get higher or lower quality, depending on your preferences. Just save your changes in Automator and compress the original file for testing ( Copy Finder Items This is exactly where it will come in handy for you).

On Windows: Resize Your PDF File with SmallPDF

On Windows, the easiest way to get a compressed PDF file is to create a new Word document or Powerpoint presentation, select "save as PDF", and select the option Minimum size before saving the file to your desktop.

And while this works well for text documents, the quality may suffer significantly if you used any design to make your document more interesting. You can also then export them to a compressed format, but again, the quality of the document will suffer.

A common method for optimizing and compressing your PDFs is to use commercial products such as Adobe Acrobat Pro and InDesign, both of which provide high-quality results and a range of options if you have access to them as part of a Creative Cloud subscription. There are free computer applications such as PrimoPDF, but when using them I noticed that either the quality suffers or the program significantly changes the file compared to the original.

Instead, you can use an online tool called SmallPDF, an online application with a set of tools for working with PDF files that you can use wherever you are, whenever you need it (and since it's an online application, you can use also on Mac, Linux, or Chromebook computers). One of these tools is Compress PDF, with which you can significantly reduce the size of your file by dropping it into an application or selecting a file on your hard drive.

I tested the app using my 25MB PDF file and it was compressed to 2MB, which is great for online publishing and mailing. The quality suffered a little, but it was quite acceptable, especially compared to how other Windows applications designed for a similar task cope with this.

Even with the help of a fairly simple converter you can reduce the size of a PDF document. But here you need to be as careful as possible; not all documents can be compressed using this method. Using a converter is considered one of the most simple ways to reduce disk space consumption.

All actions will be performed using the example application PDFConverter:

The reduced file will be stored in the folder specified in the program.

Online tools

There are a lot of sites on the Internet that allow you to compress a document in any format in just two clicks. For this it is enough:

Attention! For documents containing very important information, it is better not to use such resources. Personal or confidential information may fall into the hands of strangers.

Adobe Acrobat application

You can also try using Acrobat Reader to reduce the file size by saving it again. This method is not always suitable, in some cases it is the opposite will increase occupied disk space, so you should be careful when using it:

Compression using Adobe Acrobat DC

This method can reduce the size of very large documents. With pre-compressed files, printing to a file may not help, and in some cases the size will be increased. Therefore, the presented method should be used with extreme caution.

How to use Adobe Acrobat DC:

Printing is complete, now you can access the catalog in the saved PDF, open him or send by email.

We use Acrobat and Word

This size reduction method involves saving as a .doc in Acrobat DC and converting back using Microsoft Word or another similar text editor.

The procedure for converting formats:

Using the optimizer

Using a special PDF compressor (optimizer) is one of the simplest and most effective ways to reduce size. In this case, the user will not need to perform such difficult actions as printing to a file or changing the format.

All necessary actions will be shown using the example of the PDF Compressor application:

Archiving files

Archiving can also provide impressive results in reducing the size of any type of data. For these actions you will need to use a special archiver(WinRar, 7zip and so on). Attention, to open data compressed in this way, you also need to use an archiver.

How to compress data using 7zip:

Compression is complete, now you can open or unpack the resulting archive.

The PDF file size can be large for two reasons:

• high quality of documents, for example, a high resolution was selected when scanning;
• a large number of pages in a document, while sometimes only one or a few pages are needed from the entire document.

How to save a single page from a multi-page PDF file

We will use the resource smallpdf.com. Upload your document to the site and select the pages that should be in the final document. The selection can be made using the mouse or simply specifying the required page numbers. Then click the “Split PDF” button and download the file with the result. This way you can remove one page and also leave one page in the document.

You can also simply print the necessary pages from the document on a virtual PDF printer; how to do this is described in detail.

How to reduce the size of a PDF file

Some people try to compress PDF files with archivers (an excellent article about that), but this does not give a serious result, since any images are almost not compressed, so you need to act differently - reduce the quality of the documents.

It is better to use the same site smallpdf.com for compression. Upload your document and click "Compress PDF". In most cases, the size of the original document will be reduced very significantly.

Sometimes the size can decrease several times, while the quality, of course, will deteriorate, but it is completely uncritical.

Once a PDF document is created, it is usually very large in size; to optimize it, you need to know how to reduce the size of a PDF file.

PDF– a very popular document format among users. A universal program for viewing this format on all types of OS is Adobe Reader.

Advantages of the format:

• The quality of file display is superior to compression types such as JPEG and GIF;
• Standardization – documents with this format can be opened on all devices, and the appearance of the document will not change;
• Ensuring security - when transferring PDF files online, you can always be sure that no one will gain access to edit the file. It is also difficult to embed a virus malicious script into such files;
• Support for a large number of compression algorithms;
• Automatic detection of document authenticity.

Adobe Acrobat Pro for compression. Using Standard Features

One of the most popular programs for working with PDF files is Adobe Acrobat Pro. With its help, you can edit a previously created document and reduce its final size.

The application is paid, however, users can download a free trial version for 30 days or a portable version with reduced editing functionality.

The program allows you to significantly reduce the size of the final file.

Follow the instructions:

• Open your document in Adobe Acrobat;
• On the main panel, enable the File tab;
• Find and select “Save as another document...” and then “Reduced file size”, as shown in the figure below;

• Next, a window will appear in which you will need to specify the necessary parameters and the level of protection of the document being created;
• After converting the file, click again on the “Open” - “Optimized file” tab and in the pop-up list, click on the “Save as another...” item;
• Select a location on your hard drive where you want to save the document at a reduced size and click OK. This program allows you to perform compression without loss of quality.

In Adobe Acrobat, you can not only optimize a file, but also forcefully reduce its size.

To do this, follow the instructions:

• Open the document in the program;
• Now enable the File tab on the main toolbar of the utility;
• Select “Save as another” and in the new list that appears, click on “Reduce size”, as shown in the figure below;

This method is perfect if, after optimization, the size has not decreased to the level you need.

• In the new window, select the version of the program with which the final file will be compatible;

• Click OK to apply the options to only one file or Apply To Multiple to save the settings for several PDFs at once.

You can compress a file using the built-in functions of the Windows operating system. If the document does not open or takes too long to open, emergency compression is necessary.

To do this, you need to open the properties of the PDF file.

Then, in the general settings, find the “Other” button and in the window that opens, check the box next to the “Compress contents...” item marked in the figure below.

Save your changes by pressing OK.

This compression method is the simplest, so after compressing files whose size is several GB, the overall image of the content may be slightly distorted.

After compression, open the document in Adobe Reader to check its quality.

If it is invalid, return the original properties and optimize the file using third-party utilities.

If you need to reduce the file size only for a certain time, use data archiving utilities.

For example, 7Zip or WinRAR. In the future, if necessary, you can quickly unpack the archive and get a PDF with the initial size.

Cute PDF utility

Let's take a look at the Cute PDF program. It is one of the most common applications for converting to PDF and optimizing the final documents.

The utility is free to download and offers a wide range of features.

The program creates a virtual printer on the computer, through which the user interacts with the main functions.

To reduce the size of the desired file using Cute PDF, follow the instructions below:

• Open the document in any reader for PDF format;
• Now click on the “Print” button;

• In the window that opens to configure print settings, indicate that the printer is named “Cute PDF”, find the “Properties” or “Properties” button and click on it. In the Windows operating system, this key is located opposite the printer name;

Pay attention! If the name Cute PDF is not in the drop-down list of available printers, the program may have been installed incorrectly or you did not restart your computer after installation.

• In the window that appears, open the Compression tab, then select the desired quality level and degree of compression of the document. Save the settings and close the properties window;
• Now in the printer settings window for printing, press the Print button;
• Next, a window will appear to select where to save the document;
• Wait until saving is completed and check the size of the final file. If necessary, you can perform all of the above steps on the compressed file to further reduce its size.

Using Google Drive storage and Adobe Acrobat

You can perform compression directly through your Google drive. Adobe Acrobat must also be installed on your computer.

Login to your drive account and upload the required PDF file.

Then you need to open the PDF in your browser.

To do this, select a document from the list of previously downloaded ones, right-click on it and click on “Open” or “Open”.

Now you need to send the contents of the PDF tab to the print queue. To do this, open the print settings window in your browser settings.

Select Adobe PDF from the list of available devices. Next, click on the OK button.

Instead of the usual printing process, the process of saving the document to the computer’s hard drive will begin.

In this case, the program will automatically optimize it, which will reduce its size.

Remember! In order for the Adobe PDF item to be available in the print list, Adobe Acrobat must be installed on your personal computer. Otherwise, saving using this method will not be possible.

Compression using MS Word

The popular word processor Word from the MS Office software package will also help you reduce the size of the final PDF. Open the file using the Adobe Acrobat utility.

Then save the document as MS Word (Figure below).

Now find the saved object and right-click on it. In the pop-up list, click on the “Convert to Adobe PDF” item, as shown in the figure below.

Wait for the process to complete. As a rule, it will not take more than two minutes.

This way you can reduce the document size by approximately thirty percent without significant loss of quality.

The best online converters

Thanks to open source software, many services have appeared on the Internet that replace some desktop programs.

To reduce the size of the document you need, you can use the following services:

• Shrink PDF. Official link to the resource: http://shrinkPDF.com/ru/. This online converter allows you to reduce the size of up to 20 documents at a time without loss of quality.

To get started, click on the “Open” button and select documents on your computer for compression. Wait for the object to be loaded onto the service.

Now the file and the status of its compression process will appear at the bottom of the page. Wait for the process to complete and download the resulting file to your device.

The figure below shows an example of using the service;

Also, using this service you can instantly compress JPEG and PNG files. To do this, switch to the appropriate service tab.

• SmallPDF. Link to the main page of the site: https://smallPDF.com/ru/compress-PDF. With this service you can optimize popular formats, including PDF.

To get started, drag the file from your desktop to the red area of ​​the open page in your browser. You can also open the file using cloud storage from Google or Dropbox.

Hello everyone, my dear friends and guests of my blog. Today I will show you how to compress a PDF file for sending or uploading to a website using special programs and online services. I'm sure you work with PDFs often, but sometimes there are times when they take up so much space that they exceed the allowable upload size. What to do then? Don't be sad. All these methods are absolutely free, so you don’t even have to worry about it.

First of all, I would like to show you how you can reduce the size of a pdf file using online services without installing programs. Naturally, not everyone will want to install an additional application that will load the system, while one of these four services will come to our aid completely free of charge.

Small PDF

I'll start with my favorite service. It helps me out almost always, and it helps reduce the file size without losing quality. At least it's not noticeable.

But I want to warn you right away that this does not mean that any size will be reduced by 5 times. How lucky. It all depends on various factors.

Well, for those who are not familiar with this service, I say - you can make no more than two transactions per hour. This is a limitation of the free version. But if you need to do more operations, then the price for an unlimited monthly lop will be simply ridiculous for you.

PDF Compressor

Another pretty good online service that has proven itself well.

Of course, the main disadvantage of this service is that it cannot work with very large files. When I tried to download the previous 147 MB ​​file, I received an error about the size being exceeded.

PDF2Go

Also a very cool service that helped me out a couple of times. I didn't have any complaints while working with him.

As you can see, this document has been compressed even more powerfully than in the first case. Not even 5, but 20 times. Of course, if you don’t particularly need such a small document, then you can set the quality to better, for example 150 or 300 dpi.

I talked more clearly about the three above services in this video.

PDFio

Well, the last thing for today I would like to consider is the Pdfio service.

But sometimes this service may give you a message that our file is already compressed incredibly well and will not further reduce its weight. This is the main disadvantage. Therefore, I would not recommend that you use this thing first.

Programs for working with PDF files

Well, now let's talk about the individual applications that you will have to install. Of course, not everyone likes it, but the program will always be with you, even if the Internet is turned off.

Adobe Acrobat

Let's start with the official application from Adobe, which is the creator of the PDF format itself and therefore is completely aimed at working with it.

1. In order to compress a PDF file as much as possible, enter the program itself and open the document whose weight you want to reduce. To do this, click on the menu “File” - “Open”.
2. Now click on the "File" menu again, but now select the option "Save as different" — "Reduced PDF File".

After this, you will receive a reduced size document. But Adobe Acrobat has one more trick. You can choose "Optimized PDF File".

The difference between these two functions is that here you can adjust various settings so that you can see for yourself what you can sacrifice and what you can't sacrifice. For example, you can reduce the quality, remove active links from the document, which also affect the weight, and optimize for quick online viewing.

You can even apply custom downsampling for color and monochrome images (forced reduction in the number of pixels). Thus, by lowering the quality of graphics in Adobe Acrobat, we also reduce the size.

Naturally, this is the most convenient way. However, its disadvantage is that you need to install a special paid program. Although, who am I kidding? More than 95 percent of our users (and even more) do not purchase a license. But in fact, the program can be downloaded from the official website and used for free for 7 days.

CutePDF

This is not really a program, but rather an add-on with which you can save a PDF file from Adobe Acrobat Reader, in which this function is not available by default. If you still don’t have an Adobe reader, download it for free from Adobe website. Just be careful, as the installer imposes McAfee antivirus. Uncheck all boxes.

First you need to download for free CutePDF Writer from the official website, and then run the installer. Just don't try to find the program, it won't be there. Now follow the instructions carefully.

This add-on is pretty good considering that it's free. But of all the options I have proposed, I like it the least. The fact is that in this way it will not always help you compress the PDF file to the minimum size. Sometimes it turns out that the volume, on the contrary, also increases, especially if it initially takes up less than 1 or 2 megabytes.

Archiving

Well, perhaps I’ll tell you about the most ancient method, which helped us out at a time when there were no converters or online services. Many people forget that a file can be compressed using any archiver, for example using the free 7-zip.

If you do not have the 7-zip archiver, then you can download it from here, and then install it as a regular program.

Additionally, many email clients cannot send large files. But the archiver can split one document into several parts, which can be sent by mail and put together by regular extraction.

I just tried to reduce a file that weighs 420 kb, and in the end I ended up with an archive of less than 300 kb. That is, archiving copes well even with small volumes and after so many years, it does not lose its relevance. Naturally, this method is relevant for sending or sending by mail. And after the recipient receives the archive, he will unpack it and it will be in its original form.

You can read more about working with archivers.

Why do you need to reduce the size of documents?

Typically, these actions are carried out in three cases:

• To free up disk space. You have seen for yourself how much space can be freed up.
• For forwarding. Many sites, programs and email clients do not accept large volumes for sending and are limited to a certain maximum size. Compression can help us with this.
• Speed. The larger the document, the longer it takes to open. Sometimes, if the computer is weak, this can even lead to freezing.
