Home / Disable annotations (read-only mode)



There are some PDFs that I can’t close easily (scanned files, I’m not sure). When I press Ctrl+W or click ‘×’ a dialog warns there are unsaved annotations, even when I didn’t do nothing. I opened the file and tried to close it the next second. I guess this is a bug.

I only use SumatraPDF to read PDFs, I don’t want to do any editing. Is it possible to disable annotations entirely?


Use the standard 3.3.3 release rather than experimental 3.4 pre-release

Its easy to keep two separate portable versions. Or one installed for viewing and the pre-release for testing improvements/bugs/annotation


This works, thank you.
