Convert text to title case in 8 styles — AP, Chicago, MLA, APA, NY Times, Wikipedia, sentence case. Free online title case converter for headlines, papers, blog posts, and books.
A free title case converter that implements all major capitalization style guides correctly. Pick from AP (Associated Press, news/journalism), Chicago Manual of Style (books, academic, US publishing), MLA (humanities papers), APA (social sciences), NY Times (in-house style), Wikipedia (sentence case), classic Sentence case, or ALL UPPERCASE. Each style has its own rules for capitalizing prepositions, conjunctions, and hyphenated compounds. Compare all 8 styles side-by-side on the same input to pick the right one for your context. Preserves acronyms, Roman numerals, and brand-style mid-word caps.
AP (Associated Press Stylebook) — the standard for newspaper, magazine, and online news writing. Aggressive lowercase: prepositions and articles always stay lowercase regardless of length. Used by AP wire stories and most online news outlets that follow AP. Chicago Manual of Style (CMOS) — the standard for book publishing, academic writing, and most US trade publications. More balanced: capitalizes principal words and longer prepositions / conjunctions (4+ letters). MLA (Modern Language Association) — humanities and English-major paper standard. Similar to Chicago but explicit on hyphenated compounds. APA (American Psychological Association) — social sciences. Capitalizes major words and any word 4+ letters. Closer to Chicago than to AP. Wikipedia — sentence case for article titles (only the first word + proper nouns capitalized). Easy on the eye, distinctive, accessibility-friendly.
Capitalization style is one of the smallest editorial decisions and one of the most consistent — if you're inconsistent, readers notice immediately even if they can't articulate why. A book that uses AP-style headlines and chapter titles in different chapters reads as poorly edited. A blog with mixed AP / Chicago / sentence-case across posts looks sloppy. A research paper with the wrong style for the discipline (using AP for an APA-formatted paper) signals the author isn't familiar with the style guide. Title case is invisible when done right and glaringly wrong when done inconsistently. Pick the style your context demands and apply it everywhere — the tool here makes that one click.
Depends on your context. <strong>News article or blog headline</strong>: AP (most concise capitalization). <strong>Book, academic paper, US publishing</strong>: Chicago Manual of Style (most widely recognized). <strong>Humanities paper</strong>: MLA. <strong>Psychology / social sciences</strong>: APA. <strong>Wikipedia article</strong>: sentence case (Wikipedia's house style). When in doubt, pick Chicago — it's the closest to the "default" academic / publishing standard.
AP keeps prepositions and conjunctions of any length lowercase ("Of", "With", "By", "From" all stay lowercase). Chicago only lowercases short words (under 4 letters) — so "Among", "Between", "Through" get capitalized in Chicago but not AP. AP also takes a lighter approach in general; Chicago is more capitalization-heavy. For a 60-word headline, AP and Chicago might differ on 5-10 words.
MLA style requires both parts of hyphenated compounds to be capitalized in titles ("Self-Aware", "Co-Worker", "Up-to-Date"). Chicago and APA generally only capitalize the first part unless the second is a proper noun. AP follows Chicago. The reasoning in MLA: hyphenated compounds in titles are "title-significant" and the second part contributes meaning that should be visually emphasized. Worth picking the style that matches your style guide; mixing creates inconsistency reviewers flag.
Yes. The tool detects sequences of two or more capital letters and treats them as acronyms, preserving the original case. So "NASA Launches Webb" stays "NASA Launches Webb" in any style — never "Nasa". Same for HTML, FBI, USA, NATO, CEO, etc. Single-character "A" or "I" don't trigger this rule because they're too easily mistaken for the article and pronoun.
Preserved in their original case. "World War II" stays "World War II" — never "World War Ii" or "World War ii". The detection regex looks for sequences of I, V, X, L, C, D, M (in that case) and treats them as untouchable. Mixed-case "iv" or "ix" would not be detected as Roman numerals; only ALL-CAPS Roman numerals get this treatment.
