I just finished proofreading 100 pages of a book in Okular on Mint 13 with KDE and submitted it to the editor. Naturally, none of the comments show up on the editors machine when he opens it. He has the latest version of Acrobat running on Windows 7. Is there any way to make the notes transfer across? Failing that, does anyone have an idea for a way to export them to a text document or something?


The annotations done in Okular are stored in the ~/.kde/share/apps/okular/docdata folder.

There should be a .xml file for each annotated pdf.

In the future, you may want to use PDF X-Change viewer of Foxit Reader for Windows through Wine. These sava annotations in the pdf itself and are visible in Adobe Reader or any other pdf reader for that matter.

  • Thanks. Now all I've got to do is figure out a way to get it back into the pdf file itself. – Yitzchak Feb 27 '13 at 12:42

  • Okular Version 1.3.3 on Ubuntu 18.04, the xml files are located in ~/.local/share/okular/docdata but if you open them, they don't seem to be the content of any annotation. – Homero Esmeraldo Jun 18 '19 at 18:07

There doesn't seem to be any way to do so within Okular, but you can save Okular annotations back into pdf format with Xournal by "printing to a file":

  • Among all the solutions, this is the only one that worked with me. In Okular, I printed the file as pdf and opened the new pdf file in Windows with Acrobat reader and I found the highlights and notes. Thanks. – Nasser Jun 23 '16 at 1:05

The more recent releases of Okular save the annotations directly into the PDF.

For example, on Ubuntu, if you go to the Ubuntu Software Center and install Okular, then it should work fine out of the box.

    To save the annotation in pdf, you should use "save as...", otherwise it's not saved. – xuhdev Jul 18 '15 at 0:23

I'm using Okular 0.19.3 on Linux Mint 17.1.

I added lots on annotations, then quit. Open again with Okular, notes are there, good. Open with Adobe Reader, NO notes visible :(

Opened again with Okular, did print to a pdf file. Opened output file of print function with Adobe Reader, notes are visible, Yea :)

Will they be there on android and Mac pdf file viewers? Yes, on both platforms.

I don't have a Windows system readily available to confirm but likely yes there also.


  • Using Okular Version 1.3.3 on Ubuntu 18.04, printing the annotated version into PDF does work, but it leaves the annotations non-editable. – Homero Esmeraldo Jun 18 '19 at 18:02
