What this tool does
Converts text to Title Case using an AP/Chicago-style rule: it capitalizes most words but keeps a fixed list of short articles, conjunctions, and prepositions lowercase, unless one of them opens or closes the text.
How to use it
Type or paste text into the box; the Title Case result appears below and updates as you type. Buttons above the box switch to six other case styles — UPPERCASE, lowercase, Capitalized Case, Sentence case, aLtErNaTiNg cAsE, and iNVERSE cASE — without leaving the page.
Worked example
"the quick fox jumps over a lazy dog" becomes "The Quick Fox Jumps Over a Lazy Dog" — "the" is capitalized only because it opens the text, while "a" in the middle stays lowercase since it's one of the minor words. "a tale of two cities" becomes "A Tale of Two Cities": "a" is capitalized here because it's the first word, and "of" stays lowercase in the middle.
Method
The text is lowercased first, then split into words. Every word is capitalized except when it's on a fixed list of 21 short articles, conjunctions, and prepositions (a, an, the, and, but, or, nor, for, so, yet, as, at, by, in, of, off, on, per, to, up, via) and isn't the first or last word of the whole text — matching common AP/Chicago style guide conventions in a simplified form.
Hyphenated and multi-part words
Capitalization is applied to the whole whitespace-delimited token, not to each part of a hyphenated compound — so "well-known" becomes "Well-known" rather than "Well-Known". If you need the second half capitalized too, adjust it manually after converting.
Limitations
The minor-word list is fixed and isn't customizable, and it only recognizes English articles, conjunctions, and prepositions — it isn't designed for other languages' title-casing conventions. It also treats the input as one block of text: the first/last-word exception applies to the very first and last word overall, not to each separate line or sentence within a multi-line title.

Frequently Asked Questions
- Which words stay lowercase in Title Case?
- A fixed list of 21 short articles, conjunctions, and prepositions — a, an, the, and, but, or, nor, for, so, yet, as, at, by, in, of, off, on, per, to, up, via — unless one of them is the first or last word of the text.
- Why is "a" capitalized in one example but not another?
- The first and last word of the text are always capitalized, even if they're on the minor-word list. "a tale of two cities" capitalizes "a" because it opens the title, while "the quick fox... a lazy dog" leaves the middle "a" lowercase.
- Does it capitalize both halves of a hyphenated word?
- No — "well-known" becomes "Well-known", not "Well-Known", since capitalization applies to the whole token rather than each part around the hyphen.
- Can I switch to Sentence case or another style instead?
- Yes — UPPERCASE, lowercase, Capitalized Case, Sentence case, aLtErNaTiNg cAsE, and iNVERSE cASE are all available from the buttons above the text box.
