What is

Title Case

Title case is the capitalization style used for headlines and titles, in which the principal words are capitalized and minor words — short articles, coordinating conjunctions and (depending on the style guide) short prepositions — are left lowercase, while the first and last words are always capitalized.

Frequently Asked Questions

In AP style a preposition like “with” or “about” is capitalized because it has four or more letters, whereas Chicago (the Chicago Manual of Style) keeps every preposition lowercase regardless of length. Both styles always capitalize the first and last word, lowercase articles such as “a”, “an” and “the”, and lowercase coordinating conjunctions like “and”, “but” and “or”. The tool shows both styles side by side so you can compare.

AP capitalizes prepositions of four or more letters, while Chicago lowercases all prepositions no matter how long they are.

All six guides in the tool — APA, AP, Chicago, MLA, NYT and Wikipedia — capitalize the first and last word of a headline even if it is a short article or preposition, and they capitalize the first word of a subtitle after a colon. The per-word explanation labels exactly which words were forced to capital for this reason.

Yes — every major style guide capitalizes the first and last word of a title, plus the first word after a colon.

Every transform is computed locally in JavaScript, so your headlines never leave your device, there is no tracking, and the page works offline after the first load. It is completely free with no account required, so you can safely title-case confidential headlines, article titles or book chapters.

Yes. All capitalization runs in your browser, nothing is uploaded, and the tool is free with no signup.

Search engines typically display roughly the first 55 to 60 characters of a page title before truncating it with an ellipsis. The tool shows a live character and word count for your capitalized headline and flags it when it runs long, so you can trim it to a search-friendly length while keeping the title-case formatting.

Aim for about 60 characters or fewer so the title is not truncated in Google search results.

Detailed Explanation

Methodology

How the Headline Capitalizer Works

AnyTool Headline Capitalization title-cases a headline entirely in the browser. It splits the text into words, always capitalizes the first word, the last word and the first word after a colon, and capitalizes major words (nouns, verbs, adjectives, adverbs and pronouns). Minor words — articles, coordinating conjunctions and prepositions — are lowercased according to the rules of the selected style guide, while acronyms, Roman numerals and mixed-case brand names are preserved as typed.

First word, last word and the word after a colon are always capitalized
Hyphenated compounds are title-cased part by part
Acronyms (NASA, API), Roman numerals (IV, XII) and brands (iPhone) are kept
All capitalization is client-side JavaScript — no server round-trip

How It Works

How the Style Guides Differ

The guides agree on capitalizing the first and last word and lowercasing articles and short coordinating conjunctions, but they diverge on prepositions. APA, AP and the New York Times lowercase prepositions of three letters or fewer and capitalize longer ones, so “With” and “About” are capitalized. Chicago and MLA lowercase all prepositions regardless of length, so the same words become “with” and “about”. Wikipedia lowercases prepositions of four letters or fewer. The tool labels every word so the reason for each decision is visible.

APA / AP / NYT: capitalize prepositions of four or more letters
Chicago and MLA: lowercase all prepositions regardless of length
Wikipedia: lowercase prepositions of four letters or fewer
The four-letter preposition “with” is the classic point of disagreement
A per-word explanation states why each word was capitalized or lowercased

Privacy & Security

Batch Mode, SEO Length and Privacy

A batch mode title-cases a whole list of headlines, one per line, in the chosen style, and each result can be copied individually or together. A live length check reports the character and word count and flags titles longer than about sixty characters, the point at which search engines often truncate page titles. Because everything runs in the browser, no headline is ever uploaded and the tool works offline after the first load.
