Why Use OCR on PDFs?

Scanned documents and photographed pages are just images — you can’t search text, copy content, or highlight words. OCR (Optical Character Recognition) solves this by:

  • Making PDFs searchable in any PDF viewer or browser
  • Allowing text selection, copying & pasting
  • Enabling keyword search across long documents
  • Improving accessibility for screen readers
  • Turning paper archives into digital, editable records

How Our OCR PDF Tool Works

  1. Upload your scanned or image-only PDF
  2. Run OCR — Tesseract.js analyzes each page locally
  3. Convert — invisible text layer is added behind images
  4. Download the searchable PDF

Common Use Cases

Make old scanned contracts or legal documents searchable
Convert photographed receipts into searchable expense records
Turn handwritten notes or books into digital archives

Frequently Asked Questions

Is this OCR PDF tool 100% private?
Yes — completely. All OCR processing happens locally using Tesseract.js. Your document never leaves your device.
What accuracy can I expect?
Good to excellent on clean, high-contrast printed text in English. Handwriting, low-quality scans, unusual fonts, or non-Latin languages will have lower accuracy.
Does it support languages other than English?
Yes — Tesseract supports 100+ languages. English is loaded by default; other languages may require additional loading time on first use.
Can I use this on mobile phones/tablets?
Yes — fully responsive. You can upload scanned PDFs from your phone gallery or camera roll.
Is there a file size or page limit?
Limited by device memory & CPU. Files up to ~20–50 MB and 10–30 pages usually work well. Very large documents may be slow.
Does it work offline?
Yes — after the page and Tesseract language files load once, OCR works offline.
