What to know
Unicode-aware lowercasing, so accented and non-Latin characters convert properly. Note that a few characters do not round-trip — the German ß uppercases to SS, which does not lowercase back.
Questions
Is anything uploaded to a server?
No. Every tool on this site runs inside your browser using standard web APIs. There is no upload, no account, no logging and no server holding your data afterwards. You can confirm it by opening your browser's developer tools and watching the network tab stay empty while you work.
