    Title Case Converter: what it does and an example result

    The free title capitalization tool runs in your browser, needs no sign-up and never sends what you type anywhere.

    Quick answer

    This title capitalization tool converts a headline to AP, APA, Chicago, MLA title case or sentence case. The rule of thumb: capitalize the first and last word and all major words, and lowercase articles, short conjunctions and prepositions. AP and APA lowercase only short ones, Chicago and MLA lowercase every preposition.

    What is a title case converter?

    A title capitalization tool is a converter that applies a style guide's headline rules to your text. It capitalizes the first word, the last word and the word after a colon, then lowercases the minor words that style guide lists, such as a, and, of and to.

    Should SEO titles use title case or sentence case?

    Either is fine for SEO, because Google does not rank pages differently for capitalization. Google displays the title link from your page and may rewrite it, as its title link documentation explains. Pick one style for the whole site and use it in every title tag and H1 for consistency.

    Which words are not capitalized in a title?

    In most styles, articles (a, an, the), coordinating conjunctions (and, but, or, nor) and short prepositions (at, by, in, of, on, to) stay lowercase unless they are the first or last word. AP and APA capitalize any word of four letters or more, while Chicago and MLA lowercase all prepositions, even long ones like between.

    What is the difference between AP and Chicago title case?

    AP capitalizes every word of four or more letters, so With and About are capitalized. Chicago lowercases all prepositions regardless of length, so with and about stay lowercase. For example, AP gives "A Guide to Links With Real Value" while Chicago gives "A Guide to Links with Real Value".

    Worked example

    Example

    Example: the headline "how to get backlinks from news sites in 2026" becomes "How to Get Backlinks From News Sites in 2026" in AP (From has four letters) and "How to Get Backlinks from News Sites in 2026" in Chicago (all prepositions stay lowercase).

    Frequently asked questions

    Does capitalization affect Google rankings?

    No. Google treats title case and lowercase words the same when matching queries. Capitalization only changes how readable and professional your title looks in search results, which can influence whether people click. Choose one style and apply it across all pages.

    Why does the tool keep some of my capital letters?

    Words you type with capitals inside them, such as SEO, iPhone or WordPress, are kept exactly as typed, because they are usually acronyms or brand names. If you paste a headline in all capitals, the tool lowercases it first and then applies the style rules.

    How are hyphenated words capitalized?

    In title case, each part of a hyphenated compound is usually capitalized, for example Long-Term Results or Self-Hosted Sites. Minor words after the hyphen stay lowercase in Chicago and MLA, such as Built-in. Check compounds against your chosen style guide.

    Can the tool tell when up or over is not a preposition?

    No. The tool does not know grammar, so it treats words like up, over or on as prepositions. In phrasal verbs such as Set Up or Log In, capitalize them by hand, because they act as part of the verb, not as prepositions.

    Which style should I use for blog post titles?

    Many news and marketing sites use AP style, and many tech and documentation sites use sentence case, as in the Google developer documentation style guide. Any style works if you use it consistently in titles, headings and social posts.

    Does sentence case keep proper nouns capitalized?

    Only when you typed them with internal capitals, such as SEO or WordPress. Plain proper nouns like Google or London cannot be detected, so sentence case lowercases them. Read the result and recapitalize names before you copy it.
