How to OCR a PDF
Make a scanned PDF searchable and its text selectable.
Open PDF to TextWhat OCR does
OCR (optical character recognition) converts images of text into real, selectable text. It turns a scanned PDF into a searchable document.
When you need it
If Extract Text returns nothing, your file is likely a scan. OCR is not available in this app, so a scanned PDF needs a dedicated OCR service before its text can be edited.
Language matters
OCR accuracy depends on the document language and scan quality. Clean, high-resolution scans work best.
