Title Case Converter

Target: Book Publishing, Longform Nonfiction, Academic Monographs

Capitalizes first and last words, all nouns, pronouns, adjectives, verbs, and adverbs. Prepositions of 4 or fewer letters ('with', 'from', 'into', 'over') remain lowercase; prepositions of 5 or more letters ('through', 'between', 'without') are capitalized.

Target: Journalism, Newspapers, Wire Services, PR & Press Releases

Capitalizes all words of 4 or more letters regardless of part of speech. Lowercases articles ('a', 'an', 'the'), conjunctions of 3 or fewer letters, and prepositions of 3 or fewer letters ('in', 'on', 'at', 'by', 'for', 'of', 'to').

Target: Psychology, Behavioral Sciences, Education, Academic Research

Capitalizes major words of 4 letters or more, plus both words in a hyphenated compound ('High-Converting', 'Peer-Reviewed'). Subtitles after colons always begin with a capital letter regardless of word length.

Target: Humanities, English Literature, Cultural Studies, Scholarly Essays

Lowercases all prepositions regardless of character length—including 5-letter, 7-letter, and 8-letter prepositions like 'through', 'between', 'against', and 'without'—unless they occur as the first or final word.

Target: Medical Journals, Clinical Research, Health Sciences (JAMA)

Capitalizes all major words and prepositions of 4 or more letters. Specifically requires capitalizing two-letter coordinating or linking verbs ('Is', 'Be', 'Do') while lowercasing prepositions of 3 or fewer letters.

Target: Electrical Engineering, Computer Science, Technical Transactions

Follows standard technical headline capitalization: prepositions and conjunctions of 3 or fewer letters are lowercased; words of 4 or more letters and subordinating conjunctions are capitalized.

Target: Legal Briefs, Law Reviews, Judicial Opinions, Court Filings

Rule 8 requires lowercasing articles, conjunctions of 4 or fewer letters, and prepositions of 4 or fewer letters ('with', 'from', 'into'). Prepositions of 5+ letters are capitalized.

Target: Investigative Journalism, Literary Reviews, Features

Capitalizes all words of 4+ letters, plus short words functioning as adverbs or phrasal particles: 'No', 'Nor', 'Not', 'Off', 'Out', 'So', and 'Up'. Lowercases short articles and prepositions.

Words like 'up', 'in', 'off', 'out', and 'on' are lowercased when they function as simple prepositions ('Walking up a Hill'). However, when paired with a verb as an adverbial particle in a phrasal verb ('How to Set Up a Server', 'Log In to Your Account', 'Turn Off Notifications'), Chicago (§8.160), APA, AP, MLA, and NYT require capitalizing the particle.

Across Chicago, APA 7th (§6.17), MLA 9th (§2.90), and AP style, the first word of a subtitle following a colon (:), em dash (—), en dash (–), question mark (?), or exclamation mark (!) is always capitalized—even if it is an article ('A', 'An', 'The') or short preposition. Likewise, the final word before the colon is capitalized as the end of the main title.

The first and last elements of a hyphenated compound ('Self-Report', 'State-of-the-Art', 'Up-to-Date', 'E-Commerce') are capitalized across major style guides. Internal elements follow the selected style guide's minor-word rules (articles and short prepositions remain lowercase inside multi-word compounds).

Naive title-case scripts treat apostrophes as word boundaries, turning "don't" into "Don'T" and "rock 'n' roll" into "Rock 'N' Roll". Our tokenizer keeps internal apostrophes lowercase, preserves mid-title elisions ('n'), and protects 220+ unambiguous brand names and scientific terms (iPhone, macOS, Next.js, OpenAI, mRNA, COVID-19).
