OCR a PDF offline
Recognise text with no connection and no upload.
Because the OCR engine runs in your browser, it does not need a server, and it keeps working offline. That makes it ideal for confidential documents you do not want to send anywhere, or for working without a connection.
How to OCR a PDF offline
- 1
Load the tool
Open the page once so the engine is cached; after that it works offline.
- 2
Add your PDF
Drop in the document to recognise.
- 3
Run OCR and download
Text is recognised on your device and added to the PDF.
Why offline OCR is more private
If a tool can OCR your document with the internet switched off, it cannot be uploading it. Local recognition makes the privacy structural, not just a promise.
Frequently asked questions
Does it really work with no internet?+
Yes. After the first load the recognition engine runs locally, so you can disconnect and it still works.
Is anything uploaded?+
No. Everything happens in your browser, online or off.
Why does offline matter?+
It proves your document is never sent anywhere: there is no server involved to receive it.
Is it free?+
Yes, with no sign-up.
