OCR does it really work?

I just started using Joplin. The OCR feature does not work. I tried to upload photos w/ clear text shown, screenshots from the internet, etc, and search for the content but nothing happens. Am I doing something wrong?

OCR seems to work for me in Joplin 2.14.22 (Linux/Ubuntu 24.04). I'm testing with this PNG file and searching for "pre-releases".

Here are a few things that could be happening:

  • It can take some time for OCR to process all resources.
  • OCR needs to be manually enabled in settings > general > "Enable optical character recognition (OCR)".
  • Not all image formats are supported. For example, Joplin should OCR PNGs, JPEGs, and PDFs, but not GIFs or SVGs.
