Title Case Converter
Capitalise a heading the way style guides do, keeping short words lowercase.
This converter rewrites a heading in title case — the capitalisation style used for article titles and headlines, where the important words are capitalised and short connecting words stay lowercase. Type or paste your title and the result updates live; pick a style label and press Copy Output when it looks right. It normalises whatever you paste, so an all-caps or all-lowercase heading comes out consistently cased. Everything happens in your browser.
The rule it applies
The first and last word of the title are always capitalised, no matter what they are. In between, the tool capitalises every word except a fixed list of 16 short ones, which it keeps lowercase: a, an, the, and, but, or, nor, for, of, in, on, at, to, from, by, as. Before doing any of this it lowercases the entire input, which is why a heading pasted in BLOCK CAPITALS or messy mixed case still comes out cleanly and consistently capitalised.
About the APA, MLA, Chicago and AP buttons
The four style buttons let you label the convention you are writing for, and in this tool they apply the same shared core rule described above. Bear in mind that the real style guides differ on finer points: AP capitalises prepositions of four or more letters, Chicago lowercases most prepositions regardless of length, and they handle hyphenated compounds differently. So for strict compliance with a specific guide, treat the output as a strong first pass and check those edge cases by hand.
What it cannot know
Because the tool lowercases everything first and works purely from its word list, it has no idea about proper nouns, brand names or acronyms. Words like iPhone, NASA or PDF come out as "Iphone", "Nasa" and "Pdf", and a listed word such as "of" is lowercased even inside a name like "Bank of America" (which is usually correct, but not always). Fix those specific words manually after copying — the tool gets the bulk of the capitalisation right so you only touch the exceptions.
Frequently Asked Questions
Which words are kept lowercase?
A fixed list of 16: a, an, the, and, but, or, nor, for, of, in, on, at, to, from, by and as. They are only lowercased in the middle of the title — the first and last word are always capitalised.
Do the four style buttons give different results?
In this tool they apply the same core rule. Actual style guides diverge on details such as how AP treats longer prepositions, so double-check those cases against your chosen guide.
Will it preserve acronyms like NASA or names like iPhone?
No. The input is lowercased first, so acronyms and internal capitals are flattened (NASA becomes Nasa, iPhone becomes Iphone). Restore those by hand after copying.
Does it update as I type?
Yes. The output refreshes on every keystroke and whenever you switch style, and Copy Output copies the current heading to your clipboard. Nothing is uploaded.
