YOUR TEXT

What this tool does

A case converter changes the capitalization pattern of text you paste in — flipping between ALL CAPS, all lowercase, Title Case, Sentence case, or aLtErNaTiNg case — without changing the words themselves.

How it works

  1. Paste or type your text.
  2. Pick a case style from the tabs above.
  3. Copy the converted result.
Example: Paste "the quick brown fox" and switch styles to see "THE QUICK BROWN FOX", "The Quick Brown Fox", and "tHe QuIcK bRoWn FoX" — all from the same original text.
