OCR a PDF (Make Scans Searchable)

Convert a scanned or image-only PDF into a searchable document with a real, selectable text layer behind every word. Powered by the open-source Tesseract engine running entirely in your browser, so even sensitive scans are never uploaded.

OCR PDF

Turn a scanned or image-only PDF into a searchable PDF with selectable text behind every word. Powered by Tesseract.js (open-source). Recognition runs entirely in your browser — pages never leave your device.

Tesseract's engine and the English language model add up to roughly 12 MB. We don't download them until you ask — once initialized, the data stays cached in your browser, so subsequent visits are fast.

How it works

  1. Load the Tesseract engine (a one-time download that then stays cached).
  2. Drop in your scanned PDF.
  3. Choose searchable-PDF or plain-text output and a recognition quality.
  4. Run OCR and download the searchable result.

Frequently asked questions

Does OCR happen on a server?
No — recognition runs locally in your browser via WebAssembly. Pages never leave your device.
What languages are supported?
The default English model is included; recognition quality is adjustable for speed vs. accuracy.
Why is there a one-time download?
The OCR engine and language model are about 12 MB. They download only when you ask and then cache for next time.
