Open toolWhy these tools exist
Most online tool sites are wrapped in ads, popups, and accounts. We wanted something simpler — small utilities that load fast, work offline-ish, and don't send the text you paste to a server.
Every tool here is 100% in-browser JavaScript. Nothing you type leaves your device. They're free and will stay free.
