Make a scanned PDF searchable

Recognise text on scanned pages with an OCR engine that runs in your browser. Keep the original look with an invisible text layer, rebuild editable text, or extract plain text and Markdown.

How to use OCR PDF

  1. Open the scanned PDF.
  2. Choose pages and language (English, Hindi, Spanish, French, German, Portuguese).
  3. Review low-confidence words and fix them.
  4. Download a searchable PDF or the extracted text.

When to use it

  • Scans you need to search, copy from or quote.
  • Old letters and records that need to become editable.
  • Preparing scanned pages for redaction or AI summaries.

What to expect

  • Accuracy depends on scan quality; the review step helps you fix mistakes.
  • Handwriting recognition is experimental and much less accurate than printed text.
  • OCR is CPU-heavy: expect a few seconds per page.

Questions

Will the PDF look different after OCR?

No — in searchable mode the original page image stays exactly as it was; an invisible text layer is added on top.
