Conversor de mayúsculas
MAYÚS, camelCase, snake_case
Sobre esta herramienta
Convert text between common letter cases - UPPERCASE, lowercase, Title Case, Sentence case - and developer cases like camelCase, PascalCase, snake_case, kebab-case and CONSTANT_CASE.
Useful for renaming variables, reformatting copy, normalizing imported data, or making a heading consistent. Privvert is Unicode-aware so non-English letters (æ, ß, å, ñ) work correctly. Runs locally in your browser.

Preguntas frecuentes
Yes - Unicode-aware uppercase/lowercase rules apply, including German ß → SS and Turkish dotless i.
Title Case capitalises every major word ('The Quick Brown Fox'). Sentence case capitalises only the first word ('The quick brown fox').
Acronym handling varies between conventions. Privvert produces standard camelCase ('parseHttpUrl' → 'parseHttpUrl'); custom acronym preservation is a developer-preference setting.

Yes - the converter uses the browser's Unicode-aware case mapping, so Danish ÆØÅ, German ß, Turkish dotted/dotless I, and accented characters in French, Spanish or Portuguese all convert correctly. The one classical edge case is Turkish I, where the lowercase of "I" is "ı" rather than "i"; the tool follows the locale-independent Unicode rule.
No. Case conversion runs entirely in JavaScript in your browser tab. You can paste an entire contract or codebase and nothing leaves the page.
