Case Converter

Processed locally

Most "title case" buttons just capitalise every word, which is wrong

Title case is not "capitalise each word". Every major style guide lowercases articles, coordinating conjunctions and short prepositions when they fall in the middle of a title. The Old Man and the Sea, not The Old Man And The Sea. A converter that capitalises everything produces the second, and it looks amateurish in a way readers notice without being able to name.

The rules that matter: lowercase a, an, and, as, at, but, by, for, in, nor, of, on, or, the, to, up, via — unless they are the first or last word, which are always capitalised regardless. Chicago and AP differ at the margins (AP capitalises prepositions of four letters or more), but the core list is stable.

This converter applies that list. It will not know that "IT" in your title means information technology rather than the pronoun, because that requires understanding your sentence. Check proper nouns and acronyms by hand.

Frequently asked questions

What is the difference between title case and capitalising every word?
Title case lowercases short words like "of", "the" and "and" when they appear mid-title, and always capitalises the first and last word. Capitalising every word produces "The Old Man And The Sea", which is wrong by every style guide.
Which words stay lowercase in title case?
a, an, and, as, at, but, by, for, in, nor, of, on, or, per, so, the, to, up, via, vs and yet — unless they are the first or last word of the title.
What is the difference between camelCase and PascalCase?
PascalCase capitalises the first letter, camelCase does not. Both remove spaces. JavaScript variables use camelCase; class names use PascalCase.
When would I use CONSTANT_CASE?
For compile-time constants and environment variables in most languages. It is snake_case in uppercase.
Does the converter handle acronyms correctly?
No tool can, without understanding your text. Title case will render "NASA" as "Nasa". Fix acronyms and proper nouns by hand afterwards.
