How OCR works in ConvertiZen

OCR analyzes the pixels in your image and recognizes the characters. ConvertiZen uses Tesseract.js — the leading open-source OCR engine, compiled to WebAssembly — so recognition happens locally on your device at high speed without any server-side processing.

FAQ

What languages does the OCR support?

English, French, Spanish, German, and 50+ other languages.

Best results with clear, high-contrast scans. Poor quality reduces accuracy.

Are my images sent to a server for OCR?
