Title Case Converter (APA, Chicago, AP, MLA)
Capitalize a title correctly for APA 7, Chicago, AP, MLA 9, AMA, New York Times, Bluebook or sentence case, with every style compared side by side.
Short words such as up, out, down and over are treated as prepositions. When they belong to a verb (“Set Up”, “Log Out”) capitalize them by hand; proper nouns in sentence case need the same check.
| Style | Title |
|---|---|
| APA 7 | The Man With the Golden Gun: A Story of Up-to-Date Spies |
| Chicago | The Man with the Golden Gun: A Story of Up-to-Date Spies |
| AP | The Man With the Golden Gun: A Story of Up-to-Date Spies |
| MLA 9 | The Man with the Golden Gun: A Story of Up-to-Date Spies |
| AMA 11 | The Man With the Golden Gun: A Story of Up-to-Date Spies |
| New York Times | The Man With the Golden Gun: A Story of Up-to-Date Spies |
| Bluebook | The Man with the Golden Gun: A Story of Up-to-Date Spies |
| Sentence case | The man with the golden gun: A story of up-to-date spies |
Title case is not one rule but several. Chicago and MLA lowercase every preposition, AP and APA capitalize any word of four letters or more, and the New York Times has its own short list. This converter applies the style guide you choose, keeps acronyms such as NASA and brand names such as iPhone untouched, and shows the same title in all eight styles so you can see where they differ.
How to use this tool
- Paste one title per line; titles in ALL CAPS are fine.
- Choose your style guide, such as APA for a psychology paper or AP for a news headline.
- Copy the converted title, or compare the styles in the table.
- Check phrasal verbs and proper nouns, which no rule list can recognise.
Formula
First word (and first after a colon) → capitalized; listed minor words → lowercase; every other word → capitalized
APA 7 lowercases articles, short conjunctions and prepositions of three letters or fewer, and capitalizes both parts of hyphenated major words. Chicago lowercases articles, and, but, for, or, nor, every preposition, and to and as. AP and AMA lowercase articles, short conjunctions and prepositions up to three letters. MLA lowercases articles, every preposition and coordinating conjunctions. Chicago, AP, MLA, AMA and the NYT always capitalize the last word; APA and Bluebook have no last-word rule. Bluebook lowercases articles, conjunctions and prepositions of four letters or fewer. Sentence case capitalizes only the first word and the first word after a colon.
Example
The sample “the man with the golden gun: a story of up-to-date spies” becomes The Man with the Golden Gun: A Story of Up-to-Date Spies in Chicago, and The Man With the Golden Gun: A Story of Up-to-Date Spies in AP, because AP capitalizes the four-letter preposition “with”.
Frequently asked questions
Which words are lowercase in title case?
Articles (a, an, the) are always lowercase unless they come first. Most styles also lowercase coordinating conjunctions such as and, but and or. Prepositions are the big difference: Chicago and MLA lowercase all of them, while AP and APA lowercase only those of three letters or fewer.
Do I capitalize the word after a colon?
Yes in all the title-case styles here: the first word of a subtitle is capitalized, even if it is “a” or “the”.
Why does “Set up” come out as “Set up”?
The converter cannot tell a preposition from the second part of a phrasal verb. In “Set Up Your Account”, up belongs to the verb, so capitalize it by hand.
What should I use for headings on a website?
Either is fine if you are consistent. Many sites, including Wikipedia and most software companies, now use sentence case because it is easier to read and to apply.
