Your text is nobody's business but yours.
Most online text utilities quietly POST everything you paste to a server you'll never see. Snapastr was built as the opposite.
- 01
Nothing is uploaded
Every transform runs in your browser with JavaScript. Your text is never sent to a server, logged, or stored anywhere but your own device.
- 02
Instant, offline-ready
No network round-trips means results appear as you type — and Snapastr keeps working even with no connection.
- 03
Yours to share
Share links carry your input in the URL fragment, which browsers never transmit. Private by construction.
Free for you.
