What case modes are available?

UPPERCASE, lowercase, Title Case, Sentence case, alternating case (aLtErNaTiNg), camelCase, snake_case and kebab-case — all in one tool.

What is the difference between Title Case and Sentence case?

Title Case capitalizes every significant word. Sentence case capitalizes only the first letter of each sentence and lowercases the rest.

Does it convert already-mixed text correctly?

Yes. Words are split on spaces, hyphens, underscores and case boundaries, so input like 'product_name' or 'ProductName' converts correctly.

Is my text uploaded anywhere?

No. All conversion runs locally in your browser; your text is never transmitted or stored.
