Convert to Title Case — correct headlines, book titles, and section headings

Title Case capitalization is the standard format for article headlines, book titles, section headings, and product page titles. Getting Title Case right requires knowing which words to capitalize and which to keep lowercase — a nuanced editorial decision governed by style guides including the AP Stylebook, Chicago Manual of Style, APA Style, and MLA Style. ToolJiffy Title Case Converter applies correct AP/Chicago Title Case rules to any text instantly in your browser.

AP Stylebook and Chicago Manual of Style Title Case rules

Despite their differences in other areas, AP Stylebook and Chicago Manual of Style agree on the core Title Case rules that ToolJiffy applies:

Always capitalize:

  • All "major" words — nouns, verbs, adjectives, adverbs, pronouns, interjections
  • Any word 4 or more letters in length, regardless of part of speech (e.g., "From" is capitalized because it's 4 letters, even though it's a preposition)
  • The first and last word of the title, regardless of part of speech
  • Words following a colon (:) — these begin a new conceptual unit
  • Proper nouns and proper adjectives

Do not capitalize (unless first or last):

  • Short prepositions (3 letters or fewer): at, by, for, in, of, on, or, to, up, via
  • Coordinating conjunctions: and, but, for, nor, or, so, yet
  • Articles: a, an, the

Browser-native Title Case tokenization engine

ToolJiffy's Title Case converter tokenizes the input into words using whitespace and punctuation boundaries. For each word, it checks: (1) Is it the first or last word? (2) Is its length ≥ 4? (3) Is it in the function-word exclusion list? The function-word list includes all articles, coordinating conjunctions, and short prepositions per AP/Chicago rules. Hyphenated compounds are split on hyphens and each component evaluated independently. Post-colon words trigger forced capitalization. All processing runs synchronously in browser memory.
