A privacy-first toolbox
Thirty-one beautiful tools.
Zero data leaves your device.
Converters, generators, formatters and calculators — every one runs entirely in your browser. Nothing is uploaded, tracked, or stored on a server. Works offline once loaded.
Runs in your browser
Every tool is plain JavaScript on your device. There's no server to send your data to.
Nothing uploaded
No accounts, no cookies, no analytics, no trackers. What you type stays with you.
Works offline
Install it once and every tool keeps working with no connection. Read the privacy policy →
