Three rules every tool on this site is built against. No exceptions, no fine print.
Your data sent: 0 B
↓ 0 requests so far
↑ 0 uploads — no request carries your content
The counts come from your browser's own record of every request this page made. For the row-by-row list, open developer tools → Network: the meter reads the same record. Sending your content would need an upload call in tivr's code, and the browser policy refuses one. How this is enforced
Private by design
0 uploadsNothing you type, drop, or paste here ever touches a server. Every tool does its work in your browser. Close the tab and it's gone.
Fast, with nothing in the way
0 waitNo spinners, no sign-ups, no waiting. Open a tool and it's ready.
Free, and staying that way
$0, alwaysGood tools shouldn't sit behind a paywall or an account. Everything here is free to use, and will stay that way.
