Practical guide

When and how to use OCR PDF

OCR PDF recognizes characters in scanned pages and photographs using an on-device OCR engine. It is intended for recovering text that cannot be selected in the original file.

Recognition quality depends on the scan: straight pages, strong contrast, adequate resolution, and the correct language produce substantially better results.

  • Making old notes easier to reuse
  • Checking a scan before data entry

Quality checklist

  • Rotate and crop the scan first
