Little tools 🧰
Everything runs in your browser. What you type is never sent anywhere.

Frequently asked questions
Is the password generator safe?
Passwords come from the browser’s cryptographic random number generator and never leave your device. You choose the length and character types; the longer, the stronger.
Does a QR code expire?
No. The QR code contains your link or text directly, does not depend on an intermediary service and works forever.
Is what I type saved?
No. All tools run in your browser; what you type is not sent to a server or stored.
What does the JSON formatter do?
It pretty-prints JSON, minifies it and checks whether it is valid, telling you where the error is if there is one.
