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.

Laddar ni upp mina filer till en server?+

Nej — alla verktyg här bearbetar dina filer helt på din enhet, och inget laddas upp till en server. Det enda undantaget är AI-verktygen, som skickar den extraherade texten (inte filen) till Claude för att göra sitt jobb.

Finns det en filstorleksgräns?+

Vi sätter ingen konstgjord gräns, men eftersom bearbetningen sker i din webbläsare begränsas mycket stora filer (500+ MB eller 1 000+ sidor) av din enhets minne, inte av oss.
