How it works
Every conversion runs directly in your browser by splitting your text into words and rejoining them. Nothing is sent to a server, so it works even offline once the page has loaded.
Frequently asked questions
Is this free to use?
Yes. There's no sign-up and no limit on how much text you convert.
Do you store what I type?
No. Every conversion happens entirely client-side in your browser. See the privacy policy for details.
What's the difference between camelCase and PascalCase?
Both join words with no spaces and capitalize each word's first letter, except camelCase leaves the very first letter lowercase (myVariableName) while PascalCase capitalizes it too (MyVariableName), camelCase is the common convention for variables in JavaScript, PascalCase for class and component names.
How does word splitting work for mixed input?
Input is split into words on spaces, hyphens, underscores, and camelCase/PascalCase boundaries, so pasting already-formatted text (like a snake_case variable or a camelCase one) still converts correctly to any other case.
