How to Compress PDFs in Windows 10

Adobe’s Portable Document Format (PDF) is a universal document format that can be opened on any platform using one of the many free or commercial PDF viewers available.

It’s a very common format for sending documents via text or email as the recipient should always be able to read it. However, PDFs can be quite large, especially if they have a lot of graphics or videos. This can cause some issues when trying to send PDFs via email due to limits on attachment sizes.

Additionally, storing large PDFs on your computer can take up excessive amounts of storage space. As a result, you might be interested in learning how you can easily compress PDFs in Windows 10 in order to save storage space.

Fortunately, there are many tools available online that make compressing PDFs as quick and easy as possible. In this brief tutorial, I will show you how to use three of these free tools so that you don’t have to worry about your PDFs taking up too much space anymore.
