What is the Title Case?

The Title Case Converter applies professional title case rules to any text, capitalising the appropriate words according to different style guide standards. Different publications and academic institutions follow different rules for which words in a title should be capitalised - this tool supports AP, Chicago, APA, MLA, and general title case conventions.

The core principle of title case is to capitalise "major" words (nouns, verbs, adjectives, adverbs) and keep "minor" words lowercase (short prepositions, articles, conjunctions) - unless they appear at the start of the title. The specifics vary by style guide: AP capitalises prepositions of 4+ letters; Chicago does not capitalise prepositions at all regardless of length.

How to use the Title Case

Paste or type your text in the input. Select the style guide you need (AP, Chicago, APA, MLA, or General), and the title case output updates instantly. Multi-line input processes each line as a separate title. Click Copy to copy the converted text.
