Frequently asked questions

Which languages are supported?

The OCR engine covers major Latin-script languages out of the box; accuracy is best on clean 300-DPI scans.

Why is OCR slow on big files?

Recognition is compute-heavy and runs on your own device — that's the privacy trade-off. Pages process one by one.

Will OCR change how my PDF looks?

No — the text layer is invisible; the scan looks identical but becomes searchable.
