Writing a heading, a book title or an article title? This free title case converter capitalises it the way editors do, following AP style: major words get capitals, small words such as “of” and “the” stay lowercase, and the first and last words are always capitalised. Type or paste your title and the corrected version appears live.

The conversion runs entirely in your browser, so your titles are never uploaded. For ordinary sentences use the Sentence Case Converter instead, and check the length of a finished title with the Word Counter.

Why use Toolsvine

Title capitalisation looks simple until an editor marks it wrong. Toolsvine applies the AP rules automatically, on your own device, so draft titles, unpublished headlines and client headings never leave your computer. It is free, needs no account, and works offline once the page has loaded.

The AP title-case rules this tool follows

AP style capitalises the first and last words of a title, and every major word in between: nouns, pronouns, verbs, adjectives and adverbs. Minor words — articles and short prepositions and conjunctions — stay lowercase unless they are the first or last word. This tool also capitalises the first word after a colon, because a colon introduces a subtitle, and it capitalises both parts of a hyphenated word, so “well-known” becomes “Well-Known”.

Minor words that stay lowercase

Word type	Words kept lowercase (mid-title)
Articles	a, an, the
Conjunctions	and, but, or, for, nor
Short prepositions	on, at, to, from, by, in, of, up, as

So “the lord of the rings” becomes “The Lord of the Rings”: “The” is capitalised because it is first, “Lord” and “Rings” are major words, and “of” and “the” stay lowercase in the middle. Note that style guides disagree on details — Chicago capitalises prepositions of four letters or more, while AP keeps them lowercase — so if a publisher specifies a different guide, check its list of minor words.

What this tool does not do

It does not know proper nouns, so a name you type in lowercase, such as “london”, becomes “London” only because it is a major word, not because the tool recognises the city. Acronyms you type in capitals, such as NASA, are lowercased and re-capitalised as “Nasa”, so type acronyms back in capitals afterwards if you need them preserved.

Frequently asked questions

Is my text uploaded anywhere?

No. The conversion runs entirely in your browser with JavaScript. Your text never leaves your device, and the tool keeps working if you go offline after the page loads.

Which words stay lowercase in title case?

Minor words stay lowercase in the middle of a title: a, an, the, and, but, or, for, nor, on, at, to, from, by, in, of, up and as. The first and last words are always capitalised, even if they are minor words.

What happens after a colon?

The first word after a colon is capitalised, even if it is a minor word, because a colon introduces a subtitle. For example, “cooking: the basics” becomes “Cooking: The Basics”.

How are hyphenated words handled?

Both parts are capitalised, so “well-known” becomes “Well-Known” and “follow-up” becomes “Follow-Up”. That matches AP style for hyphenated words in titles.

Is this the same as APA or Chicago style?

Mostly, but not exactly. All three capitalise major words and lowercase short minor words, but Chicago capitalises prepositions of four letters or more, such as “from” and “with”. This tool follows AP, which keeps those lowercase. Check your publisher's guide when it matters.

Will it preserve acronyms like NASA?

No — acronyms typed in capitals are re-capitalised as ordinary words, so NASA becomes Nasa. Type acronyms back in capitals after converting, or convert only the words around them.
