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. Everything runs in your browser — no files are uploaded to any server.
