What is a title case converter?
A title case converter formats headlines and titles using the capitalization convention seen in books, articles and headlines: major words are capitalized, while short "minor" words are kept lowercase unless they open or close the title. Typing "the lord of the rings" produces "The Lord of the Rings" — not "The Lord Of The Rings" — because "of" and "the" are minor words in the middle of the title. This tool runs entirely as JavaScript in your browser, so nothing you type is ever uploaded.
Which words stay lowercase
This converter uses a common minor-word list covering articles (a, an, the), coordinating conjunctions (and, but, or, nor, so, yet), and short prepositions (in, on, at, by, of, to, up, via, with, and similar). These words are lowercased anywhere in the middle of a title. The very first word and the very last word of each line are always capitalized, and so is the first word after a colon, regardless of whether it's on the minor-word list.
Multi-line titles and lists
If you paste multiple lines — a list of blog post titles, for example — each line is treated as its own independent title. That means the first and last word of every single line gets capitalized correctly, rather than only the very first and very last word of the entire pasted block.
Common uses for title case
- Blog & article headlines — most editorial style guides expect proper title case for headlines.
- Book, movie & song titles — title case is the standard convention for creative works.
- Page titles & navigation labels — website menus and page titles commonly use title case for a polished look.
- Email subject lines — title case can make subject lines feel more intentional and professional.
- Presentation slide titles — decks and slide headers frequently use title case for consistency.
