Frequently Asked Questions
Why can regular PDF tools not extract text from scanned documents?
Scanned PDFs contain raster images rather than selectable digital font characters. OCR transforms those image shapes back into editable digital text.
What languages are supported?
We support English, Simplified & Traditional Chinese, Japanese, Korean, French, German, Spanish, Russian, and Arabic.
Is my document private?
100% private. All OCR recognition runs inside your browser using Tesseract WebAssembly with zero server transmission.
