Paste a headline (or one per line) and get correct title case instantly, in AP or Chicago style, with sentence case as a third option.
How it works
Type or paste your headline and the converted version renders live below in your chosen style. AP capitalizes words of 4+ letters; Chicago keeps prepositions lowercase regardless of length; Sentence case capitalizes only sentence starts. First and last words are always capitalized in the title styles, a word before a colon forces the next capital, and all-caps acronyms are preserved.

Frequently asked questions
What is title case?
Title case is the headline convention: major words are capitalized while short "minor" words (articles, conjunctions, short prepositions) stay lowercase, as in "The Quick Guide to Title Case". The first and last words are always capitalized.
What is the difference between AP and Chicago title case?
They disagree about prepositions. AP style capitalizes any word of 4 or more letters, so "With", "From", and "Over" are capitalized. Chicago style keeps prepositions lowercase regardless of length ("with", "from", "between"). Pick whichever your publication follows; AP is the common default for blogs and news.
When should I use sentence case instead?
Sentence case ("The quick guide to title case") capitalizes only the first word. Many modern style guides and most European publications prefer it for headlines, and Google's own products use it. This tool offers it as a third style so you can compare.
Can I convert a whole list of headlines at once?
Yes. Each line converts independently, so paste one headline per line and copy the whole converted list in one click.
How are hyphenated words handled?
Each meaningful part of a hyphenated compound is capitalized, while small words inside it stay lowercase: "state-of-the-art" becomes "State-of-the-Art", the Chicago-recommended treatment.
Will acronyms like NASA stay uppercase?
Yes. Words written entirely in capitals are treated as acronyms and preserved, unless nearly all of your text is uppercase, in which case we assume Caps Lock text and normalize everything.
Is my text uploaded anywhere?
No. Everything runs locally in your browser with no signup; your latest text and chosen style are remembered only in your own browser.
