Many PC users face the problem of not knowing how to reduce the size of a PDF document so that it becomes more compact. This article will clear up any doubts you might have about choosing a desktop converter program or an online service to compress a PDF file.

PDF (from Portable Document Format) is a format created by Adobe Systems using the capabilities of the PostScript language. It is platform independent and is designed to present printed products, documentation and presentations in electronic form.

PDF documents are suitable for exchanging information between users around the world.

Advantages of the PDF format:

  • cross-platform - the document can be seen as it was created, regardless of the platform;
  • compact, supports many information compression algorithms;
  • machine independence (it can be printed on a printer and printing unit);
  • multimedia (supports videos and audio tracks, hypertext elements, as well as page previews);
  • safety. File creators can set security options, including the ability to lock (open, edit, or print after entering a password).

You can open a PDF document using free version Adobe Reader or plugin available in most browsers. IN Google Chrome this format is supported even without installing the plugin. Editing a PDF file is possible in the paid version of Adobe Reader. Many programs have also been developed for this format and converting documents from it.

PDF files can include photographs, text information, forms, etc. The appearance of the displayed document does not depend on the type of platform: in Windows and Mac OS it will look the same both on the screen and when printed.

  2. Save the compressed files.

How is a PDF file compressed?

There are different methods used to reduce the size of a PDF file. How effectively a file is compressed depends on what data the PDF file contains. For example, PDF files with images compress well. PDF24 uses the following PDF compression methods:

  1. Removing font information that is not needed when displaying a PDF file.
  2. Reduces the image size depending on the specified DPI setting.
  3. Reduces image quality depending on the specified quality parameters.
  4. Modify PDF file and compress structural data.

PDF24 allows you to compress files without loss, but in this mode the file size may decrease slightly. How it works:

  1. Click on the highlighted area at the top of the page and select the files to compress.
  2. Switch the lossless compression mode and start compressing the file by clicking on the corresponding button.
  3. Save the compressed files.

Why is my PDF so big?

If the PDF file contains images, the file size may be large. This is usually why large PDF files are created. A text-only PDF file weighs much less. If your PDF file has images, you can use PDF24 to create small images, reducing their size and quality.

Does PDF compression degrade quality?

The PDF24 compression tool has several modes. Normal compression mode reduces the size and quality of the image as it has a greater impact on the file size. You can enable lossless compression mode, but this will have a minor effect on the size. Often deterioration in quality is not a problem. The only question is how acceptable the quality is in relation to the size.

Do PDF files compress well?

Yes, if the PDF contains images. They can be individually compressed and reduced in size. Compressing PDF files without images is not as effective.

Are PDF files compressed?

PDF files typically use internal compression tools for the objects they contain. However, such compression is not necessary. Some objects may not be compressed. The PDF creation program determines which objects will be compressed and which will not, but the PDF standard itself does not imply compression.

Is it safe to use PDF24 tools?

PDF24 takes file and data security seriously. We want users to be able to trust us. Therefore, we are constantly working on security issues.

  1. All file transfers are encrypted.
  2. All files are deleted automatically from the processing server within an hour after processing.

  4. PDF24 is owned by the German company Geek Software GmbH. All processing servers are located in data centers in the EU.

PDF files have been and still are an extremely popular document format for a long time. Moreover, the ability to edit pdf files is much weaker than other office documents, such as DOC or DOCX in Microsoft Word, ODG in LibreOffice Writer.

And yet PDF is used a huge amount computer users. Sometimes the size of a pdf file takes several kilobytes, but more often the size can reach several tens of megabytes due to the large number of pages with heavy graphic elements. This can pose certain difficulties when trying to send pdf files by email or upload them to cloud file storage.

To help you reduce the size of your pdf file, in this article I will review free tools that will help you compress the file and reduce its size. Among such tools I will present online services and individual windows applications. If you have your own options for cool pdf compressors, please recommend them in the comments.

If you're looking for a quick and easy way to make your PDF files smaller without the need for complex manipulation, then Smallpdf is for you. This is an online service that is easy to use, allowing you to simply drag and drop files onto the service and perform compression. This is really handy when you need to be able to periodically compress files from anywhere.

Smallpdf online service

While the service is fairly basic in its functionality, it does have some additional features, such as the ability to import a file from Google Drive or Dropbox and save it back to the cloud once the compression operation is complete. The only downside is that there is a limit of 2 PDF compressions per hour. If you want more, you'll have to fork out $6 a month.

Compression results are mixed. The service is configured to compress a PDF file to 144 dpi without specifying any settings. Hence the different compression ratios. For example, a 5.72 MB source file can be compressed to 3.17 MB in size without any loss in viewing quality, which is not bad at all. However, it also happens that a file of 96.98 MB in size is compressed to only 87.12 MB. This once again proves that the Smallpdf service uses the simplest algorithms to reduce the size of a pdf file. However, if you just want a smaller file size, then Smallpdf is definitely for you.

iLovePDF

Platform: online

Another online service, but one that offers a little more compression options. iLovePDF allows you to upload a file from the system, Google Drive or Dropbox, and then choose one of three compression levels. The more compression you apply, the worse the quality of the output PDF file will be. But this also means that the output file will be smaller.


Online service iLovePDF

Using the same file as in the first case, 97 MB in size and applying extreme compression, I was able to compress it to 50.29 MB, i.e. cutting it by more than half is an excellent result.

I was able to download any pdf files; They compress quite quickly, and besides, I did not notice any restrictions regarding how many times the service could be used. The only limitation of the service is downloading one file at a time.

Files are automatically deleted from the service after about an hour. This limitation can hardly be called serious. During this time, you can have time to download the resulting pdf file to your computer or send it to the cloud.

If you are looking for an online PDF compressor that compresses PDF files as efficiently as possible without significant loss of quality, try iLovePDF.

Free PDF Compressor

Platform: Windows, offline

This lightweight compressor does what you need it to do and nothing more. Although it is not updated regularly, it works great on Windows 10 and previous operating systems up to Windows XP. If online tools are unavailable to you for various reasons, then Free PDF Compressor may be useful to you.

Free PDF Compressor

Free PDF Compressor allows you to choose one of five presets to compress a PDF file. Just select the compression setting, select the path to the pdf file where the output file will be saved and click the button Compress.

My 97 MB file was compressed to 50 MB using the first compression setting. The process was faster than online services. Although, perhaps this is due to the installed hardware in the computer.

PDF Compressor

Platform: Windows, offline

If none of the above tools suits you, try PDF Compressor. Judging by the information on the resource provided, the application is guaranteed to work on Windows XP/Vista/7/8. But after checking that it works on Windows 10, I was convinced that this operating system quite suitable for PDF Compressor.

Unlike competitors, you can compress more than one file at a time, and even more: you can specify a file with a list of PDF files that you want to compress, or specify an entire folder with files.


PDF Compressor

The only caveat to PDF Compressor is that sometimes the application in free mode can be ineffective in compression. Our 97 MB file lost just over 15 MB, which is not much compared to competitors. But it’s worth changing the compression parameters and a pdf file from 97 MB left only 46 MB - this best result. It’s a pity that all compressor settings are only in the paid version.

Other ways to reduce the size of a pdf file

Compressing a PDF by changing its quality is one way to reduce file size, but it is not the only way. You can delete pages or archive the pdf in ZIP. The 4 methods above will help you choose the most suitable one and reduce PDF files quickly and with minimal losses in quality.
