How It Works

The tOGGLE cASE converter inverts the case of every letter in your text. Each uppercase letter becomes lowercase and each lowercase letter becomes uppercase, while numbers, symbols, and whitespace remain unchanged.

Examples of toggle case conversion:

• Hello World becomes hELLO wORLD
• UPPERCASE becomes uppercase
• lowercase becomes LOWERCASE
• Mixed Case Text becomes mIXED cASE tEXT

Toggle case is useful for quickly inverting text that was accidentally typed with Caps Lock enabled. Instead of retyping the entire passage, simply paste it here to swap all cases instantly. It is also used for creative text styling in social media posts and messaging.

Applying toggle case twice returns the original text, making this a perfectly reversible transformation. All processing runs entirely in your browser using JavaScript. No text is transmitted to any server.
