Invert Text Case Converter

About Invert Text Case Tool

This Invert Text Case tool instantly flips the case of every letter in your text. Uppercase letters become lowercase and lowercase letters become uppercase. For example: “This is An Example” becomes “tHIS IS aN eXAMPLE”.

It’s handy when you’ve typed with Caps Lock on by mistake, need a fun mixed-case style for social media, or want to quickly experiment with different capitalization styles without manually editing your text.

How to Use

• Type or paste your text in the input box.
• By default, the text is auto-converted as you type.
• Use the Invert Text Case button to re-run the conversion anytime.
• Choose a mode:
  • Swap ALL letters – flips case for every character.
  • Only first letter of each word – inverts just the starting letter of each word.
• Copy the output with one click or use “Swap Output → Input” to continue editing the converted text.
