How can I change the font or background color of my PDF e-book. I use Adobe reader v10 and it has no default option to change this.

Is there a way to edit the e-book to change the font or background color?

Taken from here:

  1. Open Adobe Reader. Go to Edit - Preferences - Accessibility.
  2. Make sure the "Replace Document Colors" is checked and click on Custom Color.
  3. Click "Page Background" color and then select "other color."

I don't know if the version of Adobe Reader matters or not (or if it matches what you have).

You could also consider using a different PDF view. I personally perfer SumatraPDF. It has a settings.txt file that you can edit to customize the text, background etc., which can be accessed via Settings > Advanced Options (options your default text editor for txt files).

NOTE: I am using SumatraPDF v2.4

  • I think version matters because there is not Accesibility under Preferences in not available in my version. I need a global way

    @ChristmasUnicorn: You should post your version of Adobe Reader if you must stick with using that reader. It will affect the proper answer(s). As an alternative, I have posted a different reader you can use and how to access it.

  • I already updated and I don't need to stick to that reader. I can always upgrade. +1 anyways

    Not a bad idea ;) Give SumatraPDF a try. Another good one is Foxit Reader, though I switched from that one a while back because of extra 3rd party stuff it wanted to install. That may have changed now, but I haven't looked back from SumatraPDF.

To answer the second part of your question: it is possible but not trivial to change the font and the background colour of a PDF file.

I have successfully done such edits on existing PDF files using pdfedit.
