Best free PDF readers for viewing and editing PDFs
With the portable document format (PDF), you can create professional-looking documents that can then be viewed with a PDF reader or viewer. While you often need a paid application such as Acrobat Pro to create a PDF, you can easily find a free PDF viewer for almost any popular platform. PDF readers can be standalone desktop or mobile apps, or they can be built into a Web browser.
PDF readers offer a similar and small set of features. All of them enable you to view the text and graphical elements in a PDF file. Most PDF readers let you print the contents of a PDF, and a few free readers offer simple tools for annotating or marking up the PDF and applying a digital signature. With so many good free PDF readers available, one thing you should not need to do is pay for one.
You can find PDF readers as a dedicated app or as part of a related app.
