How to use this tool

  1. Enter your text, convert to.
  2. Select Update result to view the result.
  3. Check the method and assumptions below before using the result.

The method, explained

Uppercase and lowercase use JavaScript Unicode case conversion. Simple title case lowercases the text and capitalizes ASCII letters at word boundaries.

A WORKED EXAMPLE

“hello WORLD” becomes “HELLO WORLD”, “hello world”, or “Hello World”, depending on the selected style.

What to keep in mind

Simple title case is not an editorial style guide and will capitalize small words. It is designed for English; proper nouns and acronyms may need manual correction.

Common questions

Will it preserve acronyms?

Uppercase preserves their uppercase appearance. Lowercase and simple title case may alter acronyms, so review the output.

Is the original text replaced?

No. The input stays visible while the converted result appears separately.
