Does this handle punctuation correctly?

Yes, camelCase, PascalCase, and similar styles strip punctuation and join words automatically.

Can I convert code identifiers?

Yes, snake_case, kebab-case, and CONSTANT_CASE are popular for variable and file naming.

Is my text uploaded anywhere?

No, conversion happens instantly in your browser with no network requests.

Does it work offline and on mobile?

Yes. Once the page has loaded it keeps working without a network connection, and the layout is responsive so it stays usable on phones and tablets.

Do I need an account or an API key?
