How it works

Paste text, then Copy the version you need or press Apply to replace your text with it and chain conversions.

Title Case keeps short words like “a”, “of” and “the” lower, as style guides prefer. Sentence case capitalizes after a full stop, question mark or exclamation mark.

Questions

Does it handle accented letters and other scripts?

Yes. Conversion uses Unicode rules, so é, ü, Turkish İ and Cyrillic letters change case correctly.
