What does Case Converter do?
It converts text between UPPERCASE, lowercase, Title Case, Sentence case, and a few other common casing styles.
How do I use it?
Paste your text, then click the casing style you want — the converted result appears instantly and can be copied.
Is there a limit on how much text I can enter?
No hard limit is enforced — very large blocks of text just take a little longer to process, since everything runs in your browser.
Is my text sent anywhere?
Everything runs in your browser — nothing you type or paste is sent to a server.
