FAQ

Frequently asked questions

No. We never store, share or look at your images — every file is discarded the moment processing finishes and nothing is saved. That makes it safe even for sensitive documents like passports, ID cards and bank statements.

Yes. There is no cost, no watermark and no account needed. Anonymous users get a generous daily limit, which is plenty for everyday use.
