If you can overlook this, it’s a great tool, but there are less obtrusive ones out there. Sadly, the adware side of things is pretty much everywhere: you get ‘try now’ buttons, you’re offered to use powerful tools but later are asked to pony up some cash in order to actually use them, there’s even a ‘7-day trial’ button. In our review, we reckoned that “Adobe Acrobat Reader DC is one of the best free PDF readers for anyone looking to view documents and manipulate them in some way.”

It’s simple, easy to use, and comes with all the basic features you need to interact with PDF files. If it wasn’t for the latter, Acrobat Reader would be a decent addition to your software library. The second is to convince you to upgrade to the paid version of the software (which, you’ve guessed it, has many more features, including the ability to create and edit PDF files).

The top PDF viewer is designed with two purposes in mind: the first is to enable you to read and interact with PDF files (including adding annotations and even signing a document). Adobe Acrobat Reader DC is a free PDF reader software for Windows and Mac (with Android and iOS PDF reader apps available, too). And it's our top choice for best free PDF reader overall - although we found features one massive downside.
