About OCR PDF

Make scanned PDFs searchable.

OCR PDF runs English text recognition over scanned or image-only pages and adds the result back as an invisible text layer — the page still looks exactly like the original scan, but the text underneath is now searchable and selectable. Pages that already have a real text layer are detected automatically and left alone, so re-running this on a mixed document only processes the pages that actually need it.

Why OCR PDF

Built for people who care about their documents.

Page image untouched

The visible page is byte-for-byte the same scan — only an invisible text layer is added.

Skips pages that don't need it

Native-text pages are detected automatically and left as-is.

Runs on your device

Nothing uploads to a server — recognition happens entirely in your browser.
