How to use the Title Case Converter
Capitalising a headline sounds easy until you meet words like “of”, “with” or “between”. Different style guides have different rules, and publications, universities and journals usually require one of them. This converter applies the rules for you.
In every style, the first and last words are capitalised, as are nouns, verbs, adjectives, adverbs and pronouns. The differences are in the small words. Chicago lowercases articles, coordinating conjunctions and all prepositions, whatever their length. MLA is similar but also lowercases “so” and “yet”. AP, used by many newspapers, capitalises any word of four letters or more, so “With” and “Over” get capitals. APA also capitalises words of four or more letters and lowercases short conjunctions, articles and prepositions. A word after a colon is capitalised too.
Sentence case capitalises only the first word and proper nouns, a style many websites and scientific papers prefer. The converter keeps acronyms such as NASA and FBI, brand names with unusual capitals like iPhone and eBay, and words containing numbers. All-caps input is converted properly.
Automatic rules cannot recognise every proper noun, so check names of people and places. The comparison table shows every style at once.
