- 100% confidential: your documents, photos, and records never leave your machine.
- No upload wait times: large files are processed at native hardware speed.
- Always free and unrestricted: no paywalls, daily limits, or watermarks — ever.
Open DevTools → Network and confirm: your files never touch a server.
