USING THE TOOL

Case converter, explained.

  1. Paste text into the input pane.
  2. Choose a case style and convert.
  3. Check names, abbreviations and acronyms before copying.

Capitalization follows English locale rules and recognizes Unicode letters. Capitalize Each Word capitalizes every word rather than following APA, Chicago or another title style. Sentence case lowercases the text and capitalizes letters after a period, question mark, exclamation mark or new line. It does not understand abbreviations or proper nouns.

Will acronyms and brand names stay correct?

Uppercase and lowercase modes transform all letters. Word and sentence modes can change names such as NASA or iPhone, so review the result.
