Title Case Converter — AP & Chicago Style

Capitalize headlines the way editors do. Real title case keeps small words small ("the", "and", "of") and capitalizes the words that carry the headline — in AP, Chicago, or simple style.

What makes title case different from "capitalize everything"?

Compare "The Best Way To Clean A List" with "The Best Way to Clean a List". The second is real title case: grammar words stay lowercase unless they open or close the headline, so the important words stand taller. Newsrooms codified this in style guides — AP style (used by most news sites) and Chicago style (used by most book publishers) agree on almost everything, differing mainly on longer prepositions: AP capitalizes words of four or more letters ("With", "Between"), Chicago keeps all prepositions lowercase however long they are.

How to use it

  1. Type or paste your headline in any case.
  2. Pick the style your publication uses — AP for news and blogs is the common default.
  3. Copy the converted headline.

Frequently asked questions

How is this different from the Case Converter?
The Case Converter applies mechanical case rules to whole texts (including a basic title case). This dedicated tool applies editorial rules — small-word handling, first/last word rules, and the AP/Chicago difference — which is what headline keywords actually get searched for.

What about the word after a colon?
Capitalized in all three styles, because it starts the subtitle: "Lists: A Complete Guide".
