OCR PDF

Make scanned PDFs searchable and copyable.

Upload a scanned PDF to make its text searchable.

Scanned pages get an invisible text layer: the PDF looks the same, but you can search, select and copy its text. Pages that already contain text are left unchanged.

OCR PDF online, free and private

OCR PDF turns a scanned document into a searchable PDF. Text recognition (OCR) reads each scanned page and adds an invisible text layer over the words: the PDF looks exactly the same, but you can now search it, select text and copy it.

Frequently asked questions

How do I make a scanned PDF searchable?

Choose your PDF, pick its language and click Make PDF searchable. Download the new PDF and use Ctrl+F to search its text.

Which languages are recognized?

OCR currently reads English and French text. Other languages using the Latin alphabet are partly recognized, without some accents.

No. The original pages stay as they are; only an invisible text layer is added.

Is my document uploaded?
