FAQ

FAQ

Does Title Case keep acronyms like NASA?

Yes. Words written in all caps or mixed case, like NASA, iPhone and JavaScript, are left as they are. If the whole line is in caps, it's lowercased first so HELLO WORLD becomes Hello World.

How are camelCase and snake_case words split?

Words are split on spaces, symbols and existing case boundaries, so XMLHttpRequest becomes xml_http_request and user-profile image becomes userProfileImage.

Is my text sent anywhere?

No. Everything is converted in your browser, and only your last input and options are remembered on this device.
