What does Case Converter do?
Case Converter handles a small, everyday job that would otherwise need a desktop app or a risky online uploader: switch text between upper, lower, title, camel and snake case. Everything is processed locally with standard web APIs, so results appear as fast as you can type.
Why use Case Converter?
Most alternatives ask you to register, queue your file on a server, or bury the result under adverts. Case Converter loads in under a second, keeps your input on your own device, and gives you a clean result you can copy straight away — which matters when you use a utility like this several times a day.
Example
Drop in a real sample, hit the action button and Case Converter returns the finished result immediately. Try it with a small input first to see the format, then reuse it for the real work.
