The short version

What is PDF OCR — Text Recognition?

PDF OCR is a free online optical character recognition tool that extracts text from scanned and image-based PDF documents.

Upload a PDF, select your language (13 supported including English, Urdu, Hindi, Arabic, Chinese), and the tool renders each page at high resolution and runs Tesseract.js WASM-based OCR to recognize text. Results include per-page confidence scores, and you can copy or download all extracted text. The recognition runs in your browser and your PDF is never uploaded. The language model itself is downloaded on first use for the language you pick — that is a public model file, not your document.
