Common use cases

Add a text layer so you can find names, clauses and dates with search.

Digitise receipts and paperwork

Convert paper scans into PDFs that are easier to file and retrieve later.

Prepare documents for review

Make scanned pages selectable before sending them to colleagues or legal teams.

Improve document accessibility

A searchable text layer helps PDF readers and indexing tools understand the content.

Limitations

OCR quality depends on the source scan. Blurry pages, low contrast, handwriting and complex layouts may produce incomplete or incorrect text.

Frequently asked questions

What does OCR mean?

OCR stands for Optical Character Recognition. It detects text inside scanned images and adds machine-readable text to the PDF.

Which languages are supported?

The OCR tool supports English, Spanish, French, German, Portuguese and Italian.

Will OCR change how my PDF looks?

The visual pages stay the same. OCR adds a text layer so the PDF becomes searchable and selectable.

How accurate is OCR?

Accuracy depends on scan quality, contrast, page rotation and font clarity. Clean printed text works best.

Can OCR read handwriting?

Handwriting recognition is unreliable. This tool is designed primarily for printed or typed text.
