OCR PDF

Create searchable OCR PDFs in the browser.

Use Slay PDF to run English OCR and export a searchable PDF with an invisible text layer, while keeping the source document local.

Searchable export

Add an invisible text layer to OCR output so text can be selected and searched.

English OCR

The app currently bundles English language data for browser-side recognition.

Local processing

OCR runs in the browser and avoids app-server uploads.

Make scanned PDFs easier to search.

OCR helps with scanned pages, photographed documents and image-only PDFs where the text is not selectable.

Recognition quality depends on scan clarity, rotation, contrast and language. Always review important OCR output before relying on it.
