Practical guide for OCR PDF

Example use case

OCR PDF is useful for quick PDF work when you need a browser-based tool without creating an account.

Settings explained

  • Available options depend on the selected PDF workflow.
  • Browser-side processing keeps supported files on your device.
  • Output quality depends on the original file and selected settings.

Limitations

  • Large files depend on available browser memory.
  • Encrypted or damaged PDFs may need to be unlocked or repaired first.
  • Advanced PDF features such as forms, signatures, or layers may have limited browser support.

Troubleshooting

  • If a file fails, open it in a PDF viewer first to confirm it is valid.
  • If processing is slow, try a smaller file or close other heavy tabs.
  • If output is not as expected, review the settings and process the original file again.
