If you are unable to select or highlight specific text in a PDF document in Adobe Acrobat Reader on Windows, this post will help you fix it.

With Adobe Acrobat Reader and Adobe’s online PDF editor, you can add comments, fill out forms, insert text, and even sign documents – all for free.

Need to edit a PDF document but don’t want to pay for the more expensive Adobe editors? You can add text to and sign a PDF with just the free Reader program.

Adobe offers three of the best free PDF readers we've tested, compatible across Windows, Mac, and mobile: Acrobat Reader DC, Acrobat DC (known as Acrobat Standard DC), and Acrobat Pro DC.
