What this tool does

Changes letter casing while keeping your spacing and punctuation. Title Case keeps common small words lowercase; Capitalize Each Word capitalizes every word. Alternating case starts lowercase and alternates letters only.

Sentence case capitalizes letters after sentence-ending punctuation and line breaks. It does not detect proper names or acronyms.
