Why OCR PDFs in your browser?

Scanned documents are often the most sensitive ones. Recognising their text on your device means you get a searchable PDF without ever uploading the original to an OCR service.

Frequently asked questions

Is my scan uploaded?+

No. The OCR engine, model and your file all stay in your browser. Nothing is uploaded or sent to any service.

Does it use a cloud OCR API?+

No. Recognition runs entirely on your device using a self-hosted engine, so your document is never sent anywhere.

How accurate is it?+

It works well on clear English scans. Very low-quality or skewed scans may produce some errors.

Why does it take a moment?+

OCR is heavy work and runs locally, so it takes a few seconds per page rather than offloading to a server.
