  • Bundled English OCR data
  • Runs in a background worker
  • No document upload

Tips for better results

  • OCR works best on straight, high-contrast pages. Run a crooked or faint scan through Scan to PDF cleanup first and the recognition accuracy improves noticeably.
  • Recognition runs on your device, so a long document takes real time — expect a few seconds per page and leave the tab open.
  • Always proofread numbers. Digits like 0/O and 1/l are where OCR mistakes are most costly.

Examples

Searching a scanned lease for one clause

Run OCR on the scan, download the text file, and search it for the term you need instead of reading forty pages.

Reusing text from a printed article

Photograph the pages, build a PDF, run OCR, and paste the recognised text into your own document to quote it accurately.

Frequently asked questions

Which languages are supported?
English recognition data is bundled so the tool works offline. Other alphabets and non-Latin scripts are not recognised reliably.
Do I get a searchable PDF or a text file?
You get a plain text file containing the recognised text page by page. The original PDF is left untouched.
Why is recognition slower than an online service?
Because the work happens on your own device instead of on a server. That is what allows the document to stay private.
