Scanned documents are just flat images that cannot be searched or copied. OCR recognizes text glyphs and injects an invisible text layer so you can search and copy words easily.

Client-Side Performance & Privacy

Optical Character Recognition (OCR) for PDF executes 100% inside your local browser memory sandbox using WebAssembly. Your files are never transmitted across the network or stored on external servers. For multi-gigabyte or heavily nested files, splitting into smaller sections ensures instant responsiveness on low-memory mobile devices.
