Frequently asked questions

How do I change all caps to lowercase?

Paste the text and choose lowercase, or Sentence case to keep a capital at the start of each sentence.

Can I convert to camelCase or snake_case for code?

Yes. camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE are one click each, and existing camelCase input is split correctly.

Does Title Case keep small words lowercase?

Yes. Articles and short prepositions (a, of, the, in…) stay lowercase unless they start the title.

Is anything I enter sent to a server?

No. Case Converter runs entirely in your browser, so the text and details you enter never leave your device.

Is Case Converter free?

Yes. It is completely free, with no sign-up and no watermarks.
