Frequently Asked Questions
What is OCR and how does it work?
OCR (Optical Character Recognition) reads text from scanned images or image-based PDFs and converts it into actual selectable, searchable, and copyable text. This tool uses Tesseract.js — a WASM-based OCR engine — running entirely in your browser.
Does it support Hindi PDFs?
Yes! This is one of the very few tools that supports Hindi OCR in the browser. Select "हिन्दी" or "English + हिन्दी" for bilingual documents like Aadhaar cards, government forms, and bank passbooks.
Will my file be uploaded anywhere?
No. Everything runs locally in your browser using WebAssembly (WASM). Your PDF never leaves your device. You can even disconnect from the internet after loading the page and it will still work.
What types of PDFs benefit from OCR?
Scanned physical documents, photographed papers, old bank passbooks, property papers, government certificates, and any PDF where you cannot select or copy text.
What is the output format?
The output is a standard PDF with an invisible text layer added. It looks identical to the original but is now fully searchable (Ctrl+F) and you can select/copy text from it. Compatible with Adobe Acrobat, Chrome, Edge, and all major PDF viewers.
How accurate is the OCR?
Accuracy depends on the quality of the scanned image. Clear, high-resolution scans with standard fonts typically achieve 95%+ accuracy. Handwriting is not supported.
