Title case converter
Paste one title or a list, one per line, and capitalize it with headline-style rules or every word.
Each line is a separate title. The converter lowercases everything first, so check acronyms like NASA and brand names like iPhone. It all runs in your browser: your text is never uploaded.

Headline style or capitalize every word
Pick a mode in “Mode” to set how the title case converter works. “Headline style” is the default: it capitalizes the main words and keeps short articles, conjunctions, and prepositions lowercase unless they open or close the title. “Capitalize every word” puts a capital on every word, small ones included. The same three titles come out like this in each mode:
- a tale of two cities: “A Tale of Two Cities” in headline style, “A Tale Of Two Cities” with every word
- how to set up a blog in one day: “How to Set up a Blog in One Day” and “How To Set Up A Blog In One Day”
- where are you from: “Where Are You From” in both modes, because the last word always gets a capital
Which words stay lowercase in headline style
Headline style keeps a fixed list of short words lowercase in the middle of a title. Anything not on the list gets a capital, short verbs like “Is” and “Be” included. The first and last word of each line always get a capital, and so does the word right after a colon, a question mark, or an exclamation mark:
- Articles: a, an, the
- Conjunctions: and, but, or, nor, for, so, yet
- Prepositions: as, at, by, in, of, on, per, to, up, via, with, from, into, over, than
- After a colon: “star wars: a new hope” becomes “Star Wars: A New Hope”
Title case rules differ between AP, APA, and Chicago
Style guides don't agree on every word. AP and APA capitalize words of four letters or more, so they write “With” and “From” in a title, while this converter keeps both lowercase, as Chicago style does with prepositions. Check which guide your teacher, journal, or editor follows, and fix those words by hand when it differs.
The converter also treats “up” as a preposition every time, so “how to set up a blog” comes out as “How to Set up a Blog”. Chicago style capitalizes words like “up” when they belong to a verb, as in “Set Up” or “Look Up”, so change those yourself after converting.
Where title case gets names and acronyms wrong
The converter lowercases each line before it capitalizes anything. That cleans up titles typed in all caps, like “BREAKING NEWS ABOUT THE ELECTION”, which comes back as “Breaking News About the Election”, but it also flattens words that should stay mixed. Read the result once before you paste it into a paper or a video title, and watch for these:
- Acronyms: NASA becomes Nasa
- Brand names: iPhone becomes Iphone
- Names with an apostrophe: o'brien becomes O'brien, not O'Brien
- Names like McDonald: mcdonald becomes Mcdonald
- Long titles split across lines: each line gets its own first and last capital
Frequently asked questions
What is title case?
Title case is a way of capitalizing titles and headlines where the main words start with a capital letter. In headline style, short articles, conjunctions, and prepositions stay lowercase unless they come first or last, as in “The Lord of the Rings”.
Which words should not be capitalized in a title?
In this converter's headline style: a, an, the, and, but, or, nor, for, so, yet, and short prepositions such as at, by, in, of, on, to, with, and from. They stay lowercase in the middle of a title and get a capital at the start or end.
Can I convert several titles at once?
Yes. Put each title on its own line and the converter handles them one by one, giving every line its own capital at the start and end. That works well for a list of chapter names or slide headings.
Why did NASA turn into Nasa?
The converter lowercases every line before it adds capitals, so it can fix text typed in all caps. The downside is that acronyms and brand names lose their mixed case. Retype NASA, iPhone, or any similar word by hand after converting.
Does it follow APA, AP, or Chicago style?
Not any one of them in full. Its headline style lowercases a fixed list of short words, which matches Chicago on prepositions but differs from AP and APA, which capitalize words of four letters or more, such as With and From. Adjust those words to your guide.
