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.

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.

The full version of Adobe Acrobat XI -- unlike Adobe Reader -- allows you to edit, re-save and convert PDF files, which you can use to remove images.

Adobe Acrobat Pro’s optical character recognition feature converts scanned documents into editable PDFs. Just click on the Edit PDF tool to create a fully editable copy with searchable text.
