How to disable optical character recognition in Joplin?
Do not tick / untick the "Enable optical character recognition (OCR)" box.
Not sure what you suggest, but unchecking that box doesn’t do anything.
The text is not deleted from already processed files, this only prevents this instance of Joplin from executing OCR jobs. If another instance has OCR active, the data will still be transferred for the search.
