Frequently Asked Questions

How accurate is the OCR?

Very high on clean, high-contrast scans. Accuracy drops on handwriting, blurry images, or very small fonts.

How long does it take?

Typically 1–10 seconds per page depending on device and image complexity.

Is my PDF uploaded?

No. Tesseract runs in your browser via WebAssembly — nothing is uploaded.

Can I OCR in multiple languages at once?

Yes. Select all relevant languages — Tesseract will attempt to match all of them.

What's the difference between searchable PDF and plain text output?

Searchable PDF keeps the original scan visually and overlays an invisible text layer so search/copy work. Plain text exports just the recognized words.
