What does this title case converter do?
A title case converter automates a surprisingly fiddly task: deciding which words in a heading should be capitalized and which should stay lowercase. The rules are not intuitive — "is" is capitalized but "in" usually is not, and "with" is capitalized in APA yet lowercase in Chicago. Rather than memorizing five style guides, paste your text and let the tool apply the exact rule set you need. The first and last words are always capitalized, the first word after a colon is capitalized, and hyphenated compounds are handled part-by-part.
When should you use title case?
- Book and chapter titles — publishers expect Chicago or MLA title case.
- Academic papers — headings and the title page typically follow APA or AMA.
- News headlines — newsrooms follow AP style for crisp, consistent headers.
- Blog posts and email subject lines — title case reads as more polished and professional.
How the rules differ
All five styles capitalize nouns, pronouns, verbs, adjectives and adverbs, and all five lowercase short articles and coordinating conjunctions. The disagreement is about prepositions. APA, AP and AMA use a length test — prepositions of three letters or fewer stay lowercase, longer ones are capitalized. Chicago and MLA lowercase prepositions of any length. Switch styles above and watch how a word like "Between" changes.
FAQ
- Does it capitalize the first word after a colon?
- Yes. Subtitles begin with a capital letter in every major style, and the converter handles this automatically.
- Will it lowercase a word I want capitalized?
- Minor words are only lowercased in the middle of the title. The first and last words are always capitalized.
- Can I convert a whole paragraph?
- Yes, but title case is meant for short titles. For body text use sentence case instead.
