Title Case Converter — Free Online Tool

The Title Case Converter applies the actual capitalisation rules of a named style guide — APA, MLA, or Chicago — rather than mechanically capitalising every word, which is what most converters do and what produces headings that read subtly wrong to anyone who edits for a living.

The rules genuinely differ. All three lowercase short prepositions, articles, and coordinating conjunctions unless they begin or end the title, but they disagree on where the cutoff sits. APA capitalises words of four letters or more, so "With" and "From" are capitalised; Chicago lowercases all prepositions regardless of length, so "Through the Looking Glass" keeps "through" capitalised only because it starts the title. MLA sits close to Chicago but handles hyphenated compounds differently. These are not trivia — an academic style guide is enforced by the person marking your work.

Beyond academia, the same rules are what make a headline look professionally set. "How To Write A Good Headline" reads as amateur; "How to Write a Good Headline" reads as edited. The difference is entirely in the small words.

The tool also handles the cases that mechanical conversion breaks: words after a colon start a new capitalised segment, hyphenated compounds capitalise both parts under most guides, and acronyms already in caps should be left alone rather than title-cased into something unrecognisable.
