A CamScanner alternative that respects your documents
CamScanner popularized mobile scanning — along with accounts, subscriptions, watermarks and cloud processing. ScanDocument.app takes the opposite approach: a free scanner that runs entirely in your browser, where your files stay on your device.

What you give up
Honesty matters: we don't do OCR text extraction, cloud sync between devices, or fax. If you need those, a subscription app may fit better. If you need clean, private, PDF-ready scans in ten seconds — this is the faster tool.
