Title Case Converter

We support AP Style (Associated Press), APA Style (academic), Chicago Manual of Style, MLA Format, New York Times Style, and Standard Title Case with custom rules.

The smart detection system knows which articles, conjunctions, and prepositions should remain lowercase according to each style guide. It also correctly capitalizes these words when they appear as the first or last word.

Yes, the converter automatically detects and preserves acronyms (NASA, FBI), abbreviations, proper nouns, and special terms like URLs and brand names.

Yes, the batch processing feature lets you paste multiple titles or headlines and convert them all simultaneously with consistent style guide application.

AP Style capitalizes all words of three letters or fewer, while Chicago Manual lowercases all prepositions regardless of length. Each guide has unique rules for articles, conjunctions, and specific word categories.

Articles (a, an, the), coordinating conjunctions (and, but, or), and short prepositions (in, on, at, to, for) stay lowercase unless they start or end the title - the Chicago Manual of Style convention. Every other word is capitalized, including subordinating conjunctions like "because".

Both parts of a hyphenated compound get capitalized ("State-of-the-Art Report"), except when the second part is a lowercase particle like "in" or "of" that would stay lowercase on its own. This follows Chicago rule 8.159, the same standard book publishers and most style checkers apply.

Use title case for book titles, article headlines, and heading levels in formal documents; sentence case (only first word and proper nouns) dominates modern web style - Nielsen Norman Group research finds it is easier to scan and less visually noisy. This tool produces title case; sentence case is a one-word starting point you can keep as-is.
