This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.


Okular Install Okular can be used to view, highlight and annotate (with sticky notes) both pdf and djvu files. After opening the document in Okular, press F6 (or Fn key + F6). The controls to highlight, annotate will appear(along with some more tools).

A small hitch: By default these annotations are stored outside the document. So if you mail the document to somebody, he/she will not be able to see the annotations/highlights. But there are ways around this problem (as described in the official help page of Okular)

    Using File | Save as.. the annotations will be saved into the PDF. They don't appear in Chrome, but do work in Document Viewer (evince) on Ubuntu, Foxit Reader on Windows, and Adobe Acrobat Reader on Windows. I haven't tested this in Preview on OS X. – Alain O'Dea Jul 29 '15 at 15:29

Try Xournal:

Xournal is a GTK+ application for notetaking, sketching and keeping a journal using a stylus. It can also be used to add annotations to PDF files.

  • Unfortunately, Xournal does not recognize text boundaries (as can also be seen in the screenshot) – klaus se May 7 '15 at 12:26
  • Yes, you're right, however, you can user ruler (option) and then the highlighting looks more professional. – ady Jul 8 '16 at 18:41

Try PDF-Xchange Editor and zathura. It allows you to open multiple files in tabs and functions both as a good viewer. It stores annotations/comments within the file.

To install in Ubuntu follow these instructions
