Title Case Converter
Title case is a capitalization style for titles and headlines in which the major words start with a capital letter and short articles, conjunctions, and prepositions stay lowercase. This title case converter follows the AP Stylebook rules, keeps acronyms such as NASA, and treats each line as a separate title.

Title Case Converter rules
The rules, sources, known limits, and test cases behind this converter are on Title Case Rules by Style Guide.
- Capitalize the first and last words of the title, and the words on both sides of a colon.
- Capitalize every other word unless it is on the short-word list, including short verbs and pronouns such as Is, Be, It, and We.
- Lowercase the articles a, an, and the; conjunctions of three letters or fewer (and, as, but, for, if, nor, or, so, yet); and prepositions of three letters or fewer (at, by, in, of, off, on, per, to, up, via).
- In a two-part hyphenated compound, capitalize both parts (Follow-Up). In longer compounds, short words stay lowercase (Mother-in-Law).
- Words with a capital after the first letter (NASA, iPhone, eBay) keep their capitals. A title typed entirely in capitals is converted as if it were lowercase.
- The abbreviations e.g., i.e., a.m., p.m., etc., vs., et al., and cf. stay lowercase; initialisms such as u.s. become U.S.; Ph.D. keeps its spelling.
- Each line is a separate title, and line breaks are kept.
- The converter works from word lists and does not detect parts of speech, so "up" is lowercased even when it is an adverb (Pick up the Pace).

How title case differs from sentence case
Title case capitalizes every major word ("How to Write Better Headlines for Your Blog"). Sentence case capitalizes only the first word of each sentence ("How to write better headlines for your blog") and leaves the rest lowercase, apart from words already written in capitals.

FAQ
In the AP rules this converter uses, the articles a, an, and the, and conjunctions and prepositions of three letters or fewer (such as and, but, or, in, of, on, to) stay lowercase, unless they are the first or last word or sit next to a colon.
AP style. The Chicago, APA, and MLA converters apply those guides, which differ mainly in how they treat prepositions, short conjunctions, and the last word.
In AP and APA style, yes, because it has four letters. In Chicago and MLA style, no: Chicago lowercases prepositions of four letters or fewer, and MLA lowercases prepositions of any length.
Both parts of a two-part compound are capitalized (Follow-Up, Self-Report). In longer compounds, short words stay lowercase (Mother-in-Law, State-of-the-Art).
Yes. Put each title on its own line. Every line is treated as a separate title, so each one gets its own first and last word.
