3. Copy the result

Grab it with one click and paste it wherever you need it.

Handy for naming variables and functions (camelCase, PascalCase, snake_case), CSS classes and URL slugs (kebab-case), environment variables and constants (CONSTANT_CASE), or cleaning up headings and titles (Title Case, Sentence case). Word boundaries are detected from spaces, hyphens, underscores and capital letters, so converting text that's already in one case to another just works. Everything runs in your browser, so even proprietary code and identifiers stay private. For more text utilities, try Text Tools or the Word Counter.

Case converter FAQ

What's the difference between camelCase and PascalCase?

camelCase starts lowercase (helloWorld); PascalCase capitalizes every word, including the first (HelloWorld).

Does it work on text that's already camelCase or snake_case?

Yes — word boundaries are detected from spaces, hyphens, underscores and capital letters, so you can convert directly between any supported case.

Is my text uploaded?

No — conversion happens entirely in your browser.
