Type a headline or title to convert it to proper AP/Chicago-style title case, or switch to a simple capitalize-every-word mode, then copy the result.
Consistent title case makes headlines, book titles and document headers look professional and easy to scan.
Follows the same minor-word conventions used by AP and Chicago style guides for headlines.
Automatically capitalizes the first word of a subtitle after a colon, like a real editor would.
Switch to Every Word mode instantly for a simpler, rule-free capitalization style.
Title case looks simple — capitalize the important words — but the actual rule set that AP style and Chicago style both converge on is more specific than "capitalize everything." Both capitalize the first and last word of a title no matter what those words are, and both capitalize every noun, pronoun, verb, adjective and adverb in between. The words that get skipped are a short, closed list: articles (a, an, the), coordinating conjunctions (and, but, or, for, nor) and short prepositions of four letters or fewer (as, at, by, in, of, on, per, to, up, via). Those minor words are lowercased only when they fall in the middle of a title; the moment one of them opens the title, closes it, or starts a subtitle right after a colon, it gets capitalized like any other word. That colon rule trips up a lot of manual formatting, since "a tale of persistence" becomes "A Tale of Persistence" once it follows a colon, even though "a" and "of" would normally stay lowercase mid-title. This converter applies both rules automatically, which is exactly the kind of small, easy-to-miss detail that's tedious to track by hand across a long list of headlines or document titles but takes no time at all for a script to get right consistently.
Always capitalized, regardless of whether they're minor words.
Articles, coordinating conjunctions and short prepositions stay lowercase mid-title.
The word right after a colon is treated like the start of a new title.
It's a headline capitalization style where major words are capitalized and short minor words like a, the, and, of and to are lowercased, except when they're the first or last word of the title.
Articles (a, an, the), coordinating conjunctions (and, but, or, for, nor) and short prepositions (as, at, by, in, of, on, per, to, up, via) are lowercased unless they open or close the title or follow a colon.
It switches off the minor-word rules entirely and simply capitalizes the first letter of every word, which some style guides and headline formats prefer.
Standard title case rules treat the text after a colon as the start of a subtitle, so that word is capitalized the same way the very first word of the title is.
