Title Case Converter
Convert headlines to title case under AP, Chicago, MLA, or APA rules -- the styles disagree about small words like "over," and this converter applies the actual published rules for each -- instantly, in your browser.
A title case converter capitalizes headlines according to a specific style guide — AP, Chicago, MLA, or APA — which disagree about small words like "over" and "with." 99digest’s converter applies the actual published rules for each style, entirely in your browser.
How the four styles differ
AP style capitalizes any word four letters or longer, including prepositions like "over" and "with" — only shorter articles, conjunctions, and prepositions stay lowercase. Chicago and MLA style lowercase articles, prepositions, and coordinating conjunctions regardless of length, so "over" stays lowercase even though it’s four letters. APA style follows AP’s length rule, but also capitalizes both halves of a hyphenated major word and always capitalizes the first word after a colon.
Every style always capitalizes the first and last word of the title, no matter which category that word falls into.
FAQs
Which title case style should I use?
It depends on your field: AP is standard for journalism, Chicago for books and academic publishing, MLA for humanities papers, and APA for social-science papers. If you’re not sure, check your publication or institution’s style guide.
Why is "Over" capitalized in AP but not Chicago?
AP capitalizes any word of four letters or more, including prepositions — "over" is four letters, so it’s capitalized. Chicago and MLA lowercase prepositions regardless of length, so "over" stays lowercase in those styles.
Are verbs like "is" and "be" capitalized?
Yes — verbs are always capitalized in every style, regardless of length, since they’re not articles, prepositions, or coordinating conjunctions.
