What is OCR?

A plain-English definition, and the tools that work with it.

Definition

OCR (Optical Character Recognition) is technology that reads the text inside an image or scanned document and turns it into real, selectable, searchable text. It's what makes a photo of a page copyable instead of just a picture.

  • A scanned PDF is an image. You can't select or search its words until OCR recognises them.
  • OCR quality depends on the source: sharp, straight, high-contrast scans convert far better than blurry or skewed photos.
  • After OCR, a scanned document becomes searchable and its text can be extracted, copied or converted to Word.
