OCR, optical character recognition is the technology to recognize texts from a scan and image, it is very helpful to extract data from scanned files, to translate texts in an image. Most of the times, we like this feature, but at some point, OCR is annoying, for example, in following cases:

  1. the OCR is not accurate, it has completely changed the original look of the file
  2. it becomes easier for others to steal information from my PDF after OCR, my data becomes less secure, I don’t want others to redact, copy or edit the file easily
  3. the OCR recognizes every bit in my file, it is not necessary to OCR each image that has texts in the PDF
  4. an auto OCR slows down my editing, and my editor crashes when OCR a large multi-page PDF

If you are experiencing these similar things, good news for you: we have figured out how to remove OCR from a PDF. It turns out the option is not only in the settings of a PDF editor, we have other methods to remove PDF OCR even free and online.

A few more words about removing OCR from PDF

Adobe Acrobat and online tools are both good ways to remove OCR from a PDF, but maybe, we don’t even need any of them in the first place, when we performed the OCR automatically and felt not happy with the result, we can just revert.

Our PDF editing tool highly probably has a undo or revert to previous version tool hidden in the File drop-down menu, now check back and see if you can undo OCR.

Or we might have enabled the auto back up on our system, if there is any change done to our document, they will be saved, but we still can restore a previous version. If you indeed have done this to your machine, remove OCR from PDF using your Time Machine backup on Mac( File History backup on Windows) , rather than bothering yourself with a new install.
