12 toolsWhy everything runs in your browser
Your data stays yours
A password generated on a server is a password that server has seen. Here the work happens on your device, and the page never sends a request containing what you typed.
No waiting, no limits
There is no upload, no queue and no size cap set by someone else. Compressing twenty images is as fast as your machine, not as fast as a shared server.
Fast pages
Every page here is static HTML. The interactive part loads only where it is needed, which is why tools open immediately rather than after a spinner.
