Video materials:

Why compress a PDF file at all? I understand, pictures, videos that weigh tens, if not hundreds of megabytes, the same music. They need to be squeezed. In fact, files also need to be compressed, because in some cases they can be more than a couple of kilobytes. This often applies to books and large articles with pictures.

You can quickly compress a PDF document for sending by mail, where the downloaded file size is set to a fixed size. When uploading to your website or other resource where you want to save space. There are many options for why this should be done, so in the article I will reveal all the known methods.

In the article about PDF definition, I wrote about its advantages. The format can be opened on any computer and operating system and the appearance of the document will not change. The only drawback is the size.

How to compress PDF online using services

Compressing a PDF document via the Internet is the most popular and convenient way. There are many services to carry out the process, which I will describe in this article. Here we go?

pdfcompressor.com

The resource may not be the best, but working with it is easy and convenient. To load a document into the resource window, just move it there, or click the “ Download" and select a file on disk. Suppose I take a book on computer architecture that is 19 MB in size. Now I’ll upload it to the site and see how efficiently it compresses the document.

As a result, the book was compressed by 49%, almost twice, which means its size is now 9.7 MB.

Compressing PDF format is not the only thing that can be done on the resource. It also converts images and ODT type to PDF format, PDF conversion to DOC format and vice versa, the same with HTML, PUB, ePub. The disadvantage of the service is slow loading large file to the server, so you need to be patient and wait if you decide to compress the file to 100 MB.

ilovepdf.com

The next PDF compression option is the ilovepdf.com service. Also popular, but that’s not important to us, is it? You, as a user, are interested in the effectiveness of this service. We'll check it now.

Having visited the resource, you have two methods of uploading a file to the server - click the button " Select PDF file"or drag it there. I choose the same book about computer architecture weighing 19 MB. 3 compression options immediately appear in the window - low compression, recommended and extreme. Depending on the type you choose, the quality of the document will either not be affected or will suffer more. Let's try extreme compression.

We are waiting for the PDF file to download and the compression process to begin. According to my observations, loading occurs at a low level. Approximately 60-70 Kb/s, my Internet is not shit, which means this is a limitation of the service itself.

As a result, the document was compressed by 50%, as in the previous case, and its size was 9.4 MB. We can conclude that ilovepdf.com and pdfcompressor.com cope with their task almost equally. It's up to you to choose which one is more convenient. By the way, the components of the document were not damaged, that is, images and text.

In addition to the ability to perform the process that we are currently implementing, the resource can do the following useful things:

• Merge and split PDF files;
• Compress PDF;
• Convert PDF to Word, PowerPoint, Excel, JPG and vice versa;
• Insert watermarks into the file;
• Remove security passwords;
• Flip the document at any angle;
• Uploading files from the Dropbox cloud and Google Drive.

Please note that an unregistered user can upload a file up to 160 MB; after registration, you can upload files up to 200 MB.

smallpdf.com

Almost no different from previous services, but who knows, maybe smallpdf.com can compress pdf better? This is what we will find out now.

I upload the book document in PDF format to the resource and wait for the process to complete. The result was almost identical to the previous ones - 9.6 MB.

Now the compressed file can be downloaded to your computer or saved to . By the way, the functionality of the service has the same capabilities as all other sites.

jinapdf.com

Right now, without further ado, I am uploading the book file to the jinapdf.com server. I hope that this compressor will be better than other options.

The result was much worse than the others: with 19 MB we were able to achieve compression of up to 17.4 MB. Therefore, I will not use this option.

Additional tools can be found on the website:

• Convert PDF format to Word, Text, JPG and vice versa;
• Convert image to text;
• Merge PDF;
• PDF extraction;
• PDF Splitting.

In short, nothing new and all services are eerily similar to each other.

pdfio.co

You can upload a document from a cloud computer or via a link, or by drag-and-drop. After downloading, wait a little and look at the result.

So, the beautiful and pleasant interface gave us the worst result - 18.2 MB. Probably worse could be the lack of any compression.

You can compress a pdf without losing quality, to do this you need to select “Low compression”, or slightly degrade the image quality by selecting the “High compression” option.

In addition to the “unique” functions that the resource has, you may have noticed the “Online text recognition” item. On top panel There are image compression options, various converters and converters from MP4 to GIF.

pdf.io

A very simple website with a big " Select a file» with which you need to select PDF document. There are options for downloading from the cloud or via a link.

In this case, it was possible to compress the PDF by 37%, maybe someone will have a better result, I can’t say. Rather it depends on the document.

You can download the file to your computer or upload it to Dropbox or Google Drive.

pdf2go.com

Last hope guys. I move on to the last service on this list and voice my verdict. Then I'll move on to programs.

The result is 17.48 MB.

The conclusions are obvious, only the first two services from the list provide normal tools for PDF compression files.

How to compress a PDF file using programs

To view PDF is better Total . I consider this the most convenient utility, but I did not find a compression function there.

Most effective method, compress a document of our format - run it into online tools, which I described above, and then compressed using an archiver, for example, .

Let's say I already have a compressed file. The same book in PDF format. I right-click on it to call it context menu and select the option 7-ZIP > Add to archive.

Method 1: Cute PDF Converter

The Cute PDF program replaces a virtual printer and allows you to compress any PDF documents. To reduce weight, you just need to configure everything correctly.

It is worth remembering that a decrease in quality entails file compression, but if the document contained any images or diagrams, they may become unreadable under certain conditions.

Method 2: PDF Compressor

Method 3: Save PDF at a smaller size using Adobe Reader Pro DC

Program Adobe Reader Pro is not free, but it does a great job of reducing the size of any PDF document.

The method is very fast and quite often compresses the file by almost 30-40 percent.

Method 4: Optimized file in Adobe Reader

For this method you will again need Adobe Reader Pro. Here you will have to tinker a little with the settings (if you want), or you can just leave everything as the program itself suggests.

Method 5: Microsoft Word

This method may seem clumsy and incomprehensible to some, but it is quite convenient and fast. So, first you need a program that can save a PDF document in text format (you can search for it among the Adobe line, for example, Adobe Reader or find analogues) and Microsoft Word.

That's it in three simple steps you can reduce the size of a PDF file by one and a half to two times. This occurs due to the fact that the DOC document is saved as PDF with the weakest settings, which is equivalent to compression through a converter.

Method 6: Archiver

Most the usual way compress any document, including a PDF file, using an archiver. For work it is better to use 7-Zip or WinRAR. The first option is distributed free of charge, but the second program expires trial period asks to renew the license (although you can work without it).

The PDF file is now compressed and can be used for its intended purpose. Sending it by mail will now be much faster, since you won’t have to wait long for the document to be attached to the letter, everything will happen instantly.
