Good to know
- AP and APA lowercase short minor words (3 letters or fewer, such as a, an, the, and, but, or, for, nor, on, at, to, by, of, in, up, as; APA adds so, yet, off, out, per, via). Longer words, including long prepositions, are capitalized.
- Chicago and MLA lowercase articles, coordinating conjunctions and prepositions of any length. The tool uses one list for both, and cannot tell when a preposition acts as an adverb (as in “Look Up”) or a verb, so check edge cases by hand.
- Words with capitals after the first letter (NASA, iPhone, eBay) are kept as typed when the option is on. If your whole text is in capitals, that rule is skipped so it can be converted.
Title Case Converter FAQ
Which words are not capitalized in title case?
Under AP style, the short words a, an, the, and, but, or, for, nor, on, at, to, by, of, in, up and as stay lowercase unless they are the first or last word. Other styles use slightly different lists, shown in the notes above.
What is the difference between AP, APA, Chicago and MLA title case?
AP and APA capitalize words of four letters or more, including prepositions such as “with” or “from”. Chicago and MLA lowercase all prepositions regardless of length, so “through” stays lowercase. Capitalizing the first and last word is common to all.
Why is the last word always capitalized?
Most style guides require the first and last word of a title to be capitalized, even when it would normally be a small word, so “What Are You Waiting For” ends with a capital.
Will it change NASA or iPhone?
Not when “Keep acronyms and brand names” is on, which is the default. Turn it off to apply the style to every word.
Can I convert several titles at once?
Yes. Put one title on each line. The first and last word of every line are capitalized separately.
