Title case converter

Capitalize titles and headlines correctly in AP, Chicago, APA, MLA or New York Times style. Acronyms, brand names and URLs stay as you wrote them.

Worked example

One headline, two style guides. Chicago and MLA lowercase every preposition; AP and APA capitalize prepositions of four letters or more, so "From" and "With" change.

Common mistakes

  • Capitalizing every word

    That is Capitalized Case. Title case keeps short words like "of", "and" and "the" lowercase in the middle of a title.

  • Lowercasing the first or last word

    Every style capitalizes the first and last word, even "a" or "up": "Where Are You From", not "from".

  • Lowercasing long prepositions in AP

    AP and APA capitalize any word of four letters or more, so "Between", "Through" and "With" are capitalized there.

  • Forgetting the word after a colon

    The first word after a colon starts a subtitle and is capitalized: "The End: A Story", not "The End: a Story".

  • Changing brand names and acronyms

    iPhone, eBay and NASA keep their own capitals. The converter leaves words with inner capitals and all-caps words alone.

How it works

  1. 1

    Paste your titles

    One title or many, one per line.

  2. 2

    Choose a style guide

    Each style lowercases different minor words. The rule is shown under the buttons.

  3. 3

    Copy the result

    First and last words, and the word after a colon, are always capitalized.

Questions

Which words stay lowercase in a title?
Usually articles (a, an, the), coordinating conjunctions (and, but, or, nor) and prepositions. Chicago and MLA lowercase prepositions of any length; AP and APA capitalize words of four letters or more, so "Between" and "With" are capitalized.
What about words like iPhone or NASA?
Words that already have capitals inside them, all-caps acronyms and URLs are left exactly as written.
Which style should I use?
AP for news and most blogs, Chicago for books and many publishers, APA for psychology and social sciences, MLA for humanities papers.
