Correct capitalization, per style guide

“Title case” sounds like one rule but is actually four competing rulebooks. Whether with, from, or between gets a capital letter depends entirely on whose style you follow — APA says capitalize anything of four letters or more, Chicago says a preposition is lowercase no matter how long it is, and AP splits the difference by word length alone.

Pick the style tab and paste your headline. The converter applies that guide's minor-word rules, always capitalizes the first and last word, capitalizes the first word of a subtitle after a colon, keeps acronyms intact, and handles hyphenated compounds like “State-of-the-Art” part by part.

Title case vs. sentence case

Many publications have moved to sentence case entirely — only the first word and proper nouns capitalized. It reads faster and there are no minor-word judgment calls. If that's your house style, the case converter does sentence case along with UPPERCASE, lowercase, and the developer cases.

Frequently asked questions

Which words are lowercase in a title?
Every major style lowercases 'minor words' — articles (a, an, the), coordinating conjunctions (and, but, or…), and prepositions — unless they're the first or last word. The styles differ on prepositions: APA lowercases only those of 3 letters or fewer, AP capitalizes anything of 4+ letters, Chicago and MLA lowercase all prepositions regardless of length, and Wikipedia lowercases prepositions of 4 letters or fewer.
Which style should I use?
Use the style your publication or field requires: APA for psychology and social sciences, AP for journalism and press releases, Chicago for books and general publishing, MLA for humanities papers. If you have no requirement, APA-style title case is the most common convention for blog posts and headlines.
How does it handle subtitles after a colon?
The first word after a colon is capitalized in every style, which matches all four style guides' treatment of subtitles ('The Long Game: A Study in Patience').
What about acronyms and ALL-CAPS headlines?
Acronyms like NASA or CEO are preserved as-is. If you paste an entire headline in ALL CAPS, the tool detects it, lowercases it first, and then applies the style rules — otherwise every word would be mistaken for an acronym.
Can I convert several headlines at once?
Yes — put one headline per line. Each line is converted independently, with its own first-word and last-word capitalization.
