What's the difference between the case styles?
| Style | Example | Rule |
|---|---|---|
| Title Case | The Lord of the Rings | Capitalizes major words; keeps short articles, conjunctions, and prepositions lowercase (except first/last word) |
| Sentence case | The quick brown fox jumps. | Capitalizes only the first letter of each sentence |
| lower case | the quick brown fox | Every letter lowercase |
| UPPER CASE | THE QUICK BROWN FOX | Every letter uppercase |
| Capitalize Each Word | The Lord Of The Rings | Every word's first letter capitalized, no exceptions |
The easiest style to confuse is Title Case with Capitalize Each Word. They look almost identical, but Title Case deliberately lowercases short connecting words like "of," "the," and "and" in the middle of a title, while Capitalize Each Word capitalizes literally everything — compare "The Lord of the Rings" (Title Case) against "The Lord Of The Rings" (Capitalize Each Word) to see the difference.
Which words stay lowercase in Title Case?
Articles (a, an, the), short coordinating conjunctions (and, but, or, nor, for, so, yet), and short prepositions (at, by, in, of, on, to, up, as, if, is, off, out, per, via, vs) all stay lowercase — unless one of them is the first or last word of the title, in which case it's always capitalized regardless. Style guides (AP, Chicago, APA, MLA) disagree slightly on the exact edge cases, so if you're writing for a publication with a specific house style, double-check the rare exceptions; this converter follows the common convention shared by most general-purpose title case tools.
A note on Sentence case
Sentence case capitalizes the first letter after the start of the text and after any period, question mark, or exclamation point followed by a space. It's a plain text pattern, not true grammatical sentence detection — it won't know that "Dr." ends in a period but isn't the end of a sentence, so double-check text with abbreviations before using the result as-is.
