About the Title Case Converter

Title case is not simply "capitalise every word". Every style guide keeps certain short words lowercase, and they disagree about which ones. AP style lowercases prepositions of three letters or fewer; Chicago lowercases them regardless of length; APA capitalises any word of four letters or more. Doing this by eye is how inconsistent headlines happen.

This converter implements four real style guides rather than one generic rule. It always capitalises the first and last word whatever their length, handles hyphenated compounds so that "State-of-the-Art" comes out correctly, keeps recognised acronyms in capitals, and capitalises after a colon where the style requires it. Words you always want left alone — brand names such as "iPhone" or "eBay" — can be added to a protected list.

Key features of the Title Case Converter

Four real style guides

AP, Chicago, APA and MLA each apply their own rule for which short words stay lowercase, rather than one generic approximation.

First and last word always capitalised

The rule every style shares, and the one most hand-written headlines break.

Hyphenated compounds handled

"State-of-the-Art" comes out as an editor would write it, not as "State-Of-The-Art".

Protected words list

Add brand names such as iPhone or eBay and their own capitalisation survives the conversion.

Batch mode

Paste a list of headlines one per line and every one is converted independently.

Articles (a, an, the), coordinating conjunctions (and, but, or, nor, for, yet, so) and short prepositions. The exact list depends on the style: AP lowercases prepositions of three letters or fewer, Chicago lowercases them regardless of length.
