Questions people ask
Is Case Converter free?
Yes. It is a free extension with no account requirement and no paid upgrade.
Does my text leave the browser?
No. Conversion, cleanup and slugify all run inside the popup. The only permission it requests is local storage, for your preferences.
What does Slugify do?
It turns a title into a URL-ready slug with the separator you choose, transliterating accented characters to ASCII.
