Case Converter — frequently asked questions

What is Title Case vs Capitalize Each Word?+

Capitalize Each Word capitalises every word. Title Case follows style rules — small words like 'and', 'the', 'of' stay lowercase unless they are first or last.

Does camelCase / snake_case strip punctuation?+

Yes — programmer cases remove spaces and punctuation and join the words, since that is how identifiers are written.

Can I undo a conversion?+

Your original text stays in the top box, so you can re-run a different case at any time.

Pugeu els meus fitxers a un servidor?+

No: cada eina aquí processa els teus fitxers totalment al teu dispositiu, i no es puja res a un servidor. L'única excepció són les eines d'IA, que envien el text extret (no el fitxer) a Claude per fer la seva feina.

Hi ha un límit de mida de fitxer?+

No imposem cap límit artificial, però com que el processament passa al teu navegador, els fitxers molt grans (500+ MB o 1.000+ pàgines) estan limitats per la memòria del teu dispositiu, no per nosaltres.
