Frequently asked questions
How accurate is OCR?
Clean 300 DPI scans usually reach 95–99% accuracy. Blurry photos, handwriting and unusual fonts reduce accuracy.
Why is it slow?
Recognition runs on your device (Tesseract OCR in WebAssembly). Expect a few seconds per page.
Is my document uploaded?
No — only the OCR engine and language data are downloaded from a CDN; your file stays on your device.
