Convert Case's answer
Convert Case started in 2006 as a simple text case converter and grew organically into a full toolkit as users asked for more utilities. The goal has always been the same: give people fast, reliable tools without the friction of sign-ups, paywalls, or bloated interfaces.
Convert Case's answer
Convert Case is built with PHP and modern web technologies, with all processing handled client-side in the browser where possible to keep things fast and private.
