Title Case Converter

Title case is a set of rules for capitalizing words in headings and titles. Most words are capitalized, but certain short words like articles (a, an, the), prepositions (in, on, at, to, by, for, of), and conjunctions (and, but, or, nor) are kept lowercase unless they are the first or last word.

For example, "a walk in the park" becomes "A Walk in the Park" in title case. Notice that "in" and "the" remain lowercase because they are short words in the middle of the title, but the first "A" is capitalized because it starts the title.

Title case capitalizes the first word of a title along with all major words. Short prepositions (in, on, at), conjunctions (and, but, or), and articles (a, an, the) are typically left in lowercase unless they are the first word. Style guides differ on the details: which prepositions count as short, which conjunctions stay lowercase, and whether the last word is always capitalized. The core principle is the same in all of them: capitalize the important words so the heading reads clearly. The style tabs above the converter apply each guide's rules, and the table below compares them.

On the General tab, the converter keeps articles (a, an, the), the coordinating conjunctions and, but, for, or, and nor, and the short prepositions as, at, by, in, of, on, per, to, via, and vs lowercase, unless they are the first or last word of the title or come right after a colon. Verbs are always capitalized, however short, so "is" becomes "Is". Words such as up, off, so, and yet are capitalized, because in a title they are usually part of a phrasal verb or an adverb ("Set Up Your Account", "Not Yet"). Both parts of a hyphenated word are capitalized ("Well-Known"), except for short words in the middle of a longer compound ("State-of-the-Art"). Style guides differ on the details: AP and APA capitalize every word of four or more letters, Chicago and MLA lowercase every preposition whatever its length, and APA and Bluebook do not require the last word to be capitalized. Pick a style tab to follow one of them exactly.

Type or paste your text into the left panel and the title-cased version appears in the right panel automatically. Choose a style guide from the tabs above the text, and the rule it follows is shown under the result. The settings under the converter can keep words you typed in all caps, such as an acronym the converter does not know, and turn curly quotes into straight ones. You can then copy or download the result.

This Is a Capitalized Title Example.

The converter recognizes approximately 3,000 proper nouns and abbreviations. After applying standard title case rules, it corrects words like NASA, iPhone, JavaScript, PostgreSQL, and place names like New York and Los Angeles to their canonical casing. This prevents acronyms from being incorrectly formatted as "Nasa" or "Html" in title case output.

The dictionary may not cover every proper noun, especially uncommon personal names or niche terms. If a word is not in the built-in list, it will follow the default title case rules.

Use the style your publisher, school, or field asks for. AP is the usual choice for news, press releases, and many blogs. APA is used in psychology, education, and the social sciences for paper titles, headings, and titles of works named in the text. Titles of articles and books in an APA reference list take sentence case instead. Chicago is common in book publishing and history, MLA in literature and the humanities, AMA in medical journals, and Bluebook in US legal writing. If nobody has set a style, pick one and use it for every heading so they match.

The differences show up in a few words. "A walk through the woods" is "A Walk Through the Woods" in AP and APA, which capitalize words of four or more letters, but "A Walk through the Woods" in Chicago and MLA, which lowercase every preposition. "What are you looking for" ends in "For" in most styles and "for" in APA and Bluebook, which do not require a capital on the last word.

The same word can play different roles. "In" is a preposition in "Life in the City" and stays lowercase, but it is part of the verb in "Log In to Your Account" and every style guide capitalizes it there. The same goes for up ("Set Up"), out ("Find Out"), over ("Take Over"), and by ("Stand By"). Likewise "but" is a conjunction in "Small but Mighty" and a preposition meaning "except" in "All but One", and "a" is an article in "A Day Out" but a noun in "Vitamin A".

The converter goes by the word rather than its role, so a style that lowercases a preposition lowercases it as part of a verb too. The General tab capitalizes up, out, and off, which are more often part of a verb in a title. When a title uses one of these words as part of a verb, check it and capitalize it by hand.

Every style capitalizes the first word, the first word after a colon, and all nouns, pronouns, verbs, adjectives, and adverbs, and keeps the articles a, an, and the lowercase in the middle of a title. They differ in the small words:

Title case capitalizes most words in a heading, giving it a more formal and traditional appearance. Sentence case capitalizes only the first word and proper nouns, creating a more conversational and modern tone. Title case is the standard in most published books, newspapers, and academic papers. Sentence case is popular for blog posts, UI elements, and brands that favor an approachable voice. Choose the style that matches your audience and maintain it consistently across your content.
