Another PDF compression method in Adobe Acrobat DC

To do this, in the left part of the window, left-click on one or another item, and in the right part, change the parameters.

Way to Compress PDF Files on Mac OS X

PDF documents created by Mac OS X are noticeably larger than files with the same content created using Adobe Acrobat. If you are a Mac OS X user and would like to reduce the size of the PDF you have created, do the following:

Open the TextEdit application, then in the program menu, click on the "File" item, and then select "Print".
In the lower left corner of the window that opens, you will see a button with the name PDF. Click on it, and then on the line "Compress PDF" in the drop-down list. As a result, you will get a more compact PDF file.

File archiving

To make the document take up less space on your computer, you can archive it using one of the archivers, for example, 7Zip or WinRAR. Both programs are quite popular, but the first is distributed free of charge, and you will have to pay for using the second over the period limited by the trial version.

To compress a document using the 7Zip archiver, right-click on the file, then left-click on the 7Zip line first, and then on the inscription "Add to" file_name ". Then the archive will be created automatically.

If you want to set certain parameters before archiving, select the line "Add to archive". Then a window like the one in the screenshot below will open.

Using the archiver, you can significantly reduce the size of the document, as well as create an archive consisting of several files, compressed and combined with each other. This will greatly facilitate their storage and transmission by e-mail. Just before sending an archived PDF file, make sure that the recipient also has an archiver installed, otherwise he will not be able to open the archive.

Note A: Adobe Acrobat and Adobe Reader are not the same thing. Reader is free, but its PDF editing features are extremely limited, so you can only reduce the size of documents in Acrobat. However, Adobe Acrobat is a paid program. And if you do not have it and you do not want to buy it, use other options for compressing PDF documents that are not related to it.

PDF files can be compressed for different purposes, or you need to reduce the PDF size for various reasons. Think about the CV you submit online and by mail. PDF files cannot be perceptibly large when mailed if you want the PDF file to reach the recipient. The mailbox is not always large and of course there is a risk that the recipient's mailbox will not accept your PDF file. Inexperienced users do not pay attention to file size. The resume PDF file can sometimes be very large if you don't pay attention to some points. Resume often contains images and that's why PDF files get big, this is something that is often left out because the user didn't pay enough attention to it when the file was created.

In case you want to take care of PDF size even though you've never done it before, don't worry, we've developed a small program that takes care of this task. This program is part of PDF24 Creator and is called PDF24 Compress. You can download the latest version of PDF24 Creator right now from this page. The program is free and used by millions of users.
