What is OCR and what does it do?

OCR (Optical Character Recognition) scans image-based PDF pages and creates an invisible text layer, making the PDF searchable and copy-pasteable.

Which languages does OCR support?

Our OCR engine (Tesseract) supports over 100 languages. English is the default for best accuracy.

The visual appearance remains the same. OCR only adds an invisible text layer beneath the existing page images.

Make scanned and image-based PDFs searchable and selectable.
