About this title case converter
Title case capitalizes the important words of a title and leaves short function words such as "of", "the", and "and" in lowercase. Style guides disagree on which words count as minor, so this converter follows six sets of rules: a smart default for blogs and web pages, APA for psychology and social sciences, Chicago for books and publishing, MLA for the humanities, AP for news, and a simple mode that capitalizes every word. The first word, the last word, and the first word after a colon are always capitalized, acronyms such as NASA are kept, and brand spellings such as iPhone are left alone.
How to use this converter
- Add your title. Type or paste a title, or press an example. For several titles, put each one on its own line and turn on multi-line mode.
- Choose a style. Pick Smart for general use, or the style guide your school, publisher, or newsroom asks for.
- Press Convert to title case. The converted title appears with changed words highlighted, plus the same title in every other style.
- Copy the result. Press Copy title to paste it into your document or CMS.
Frequently asked questions
Which words stay lowercase in each style?
Smart keeps articles (a, an, the), coordinating conjunctions (and, but, or, nor, for, so, yet), and prepositions of four letters or fewer in lowercase. APA and AP lowercase only minor words of three letters or fewer, so words such as "Over" and "With" are capitalized. Chicago and MLA lowercase every preposition, however long, such as "between" and "through".
Are the first and last words always capitalized?
Yes, in every style. The first word after a colon, a dash, a question mark, or an exclamation mark is also capitalized, because it starts a subtitle.
What does Preserve acronyms do?
A word written in capitals with at least two letters, such as NASA, HTML, or FBI, stays in capitals. Turn it off to convert text that was typed entirely in capitals, such as "NASA LAUNCHES NEW ROCKET".
How are hyphenated words handled?
Each part follows the same rule as a separate word, so "state-of-the-art" becomes State-of-the-Art. The first part is always capitalized when the hyphenated word starts the title.
Why did a word like iPhone not change?
Words that already have a capital letter after the first letter, such as iPhone, eBay, or McDonald, are treated as deliberate spellings and kept exactly as typed.
What does multi-line mode change?
With it on, each line is a separate title, so the first and last word of every line are capitalized. With it off, the whole text is one title and only its very first and last words get that rule.
