Does this change my original text?

No. Your input stays on the left and the converted text appears on the right, updating live as you switch styles.

Is there a length limit?

No practical limit — conversion happens instantly in your browser, even for long text.

How does it decide word boundaries when converting from camelCase or snake_case?

It splits on spaces, punctuation, underscores and hyphens, at lowercase-to-uppercase changes, and between an acronym and the next word, so getHTTPResponse becomes get, HTTP, Response.

Does it preserve acronyms when converting case?

In identifier styles an acronym is treated as a word, so HTTP becomes http in snake_case and Http in PascalCase. UPPER CASE and CONSTANT_CASE keep it uppercase.

Can I convert multiple lines at once?

Yes. Identifier styles (camelCase, snake_case and so on) convert each line separately, and you can tick Each line separately for the other styles too.

Does it work with accented and non-Latin letters?

Yes. Case changes use full Unicode rules, so é, ñ, ü and Cyrillic or Greek letters convert correctly.
