Frequently asked questions
Is OCR free?
You can load any file for free. Extracting and downloading the text is included with the $6.99 Day Pass — 24 hours of unlimited use, no subscription.
What does OCR do?
OCR (optical character recognition) reads the text inside a scanned image or photo and turns it into real, selectable text you can copy, search and reuse.
How accurate is it?
If your PDF already contains real text, we use it directly — perfect accuracy, instantly. For scanned pages, photos and images, OCR is very good on clear printed text; handwriting, low-resolution scans or unusual fonts may produce some errors.
Is my document private?
Completely. OCR runs entirely inside your browser using WebAssembly — your file is never uploaded to a server.
