Frequently Asked Questions
Does OCR change how my document looks?
No — OCR adds an invisible, searchable text layer behind the original scanned image; the visible page looks exactly the same.
Is my file uploaded to a server?
No. This tool runs entirely in your browser — your file is never uploaded anywhere, so nothing ever leaves your device.
