About this tool
Handy for fixing text typed with Caps Lock on, formatting headlines, and converting identifiers between programming conventions. Title Case keeps short words (a, an, the, of, and…) in lowercase unless they start the title, following common style guides.
Frequently asked questions
What is the difference between Title Case and Capitalized Case?
Capitalized Case capitalises every word. Title Case leaves small connecting words (of, the, and, in…) lowercase, as in book and article titles.
What is camelCase vs PascalCase?
Both join words without spaces and capitalise each word; camelCase starts with a lowercase letter (userName) and PascalCase with uppercase (UserName).
Does it work with accented characters and other languages?
Yes — conversion uses Unicode-aware upper/lowercasing, so é, ß, Ω and so on are handled correctly.
