What is PDF OCR?
PDF OCR renders pages from an image-only or scanned PDF and applies optical character recognition to produce editable text. It is useful when selecting or searching the original document returns nothing, although recognition accuracy still depends on scan clarity, language, orientation, and layout.

- 2.Select all pages or specify only the page range that needs recognition.
- 3.Run OCR and wait while each selected page is rendered and analyzed.
- 4.Review and correct the extracted text before copying it or downloading a TXT file.
