What Is Toggle Case?

Toggle case flips the capitalization of each letter in your text: uppercase letters become lowercase, and lowercase letters become uppercase. It's especially useful when you've typed something in the wrong case — like accidentally leaving Caps Lock on — and want to correct it without retyping.

Input:
tOGGLE cASE IS vERY hANDY

Output:
Toggle Case Is Very Handy

When Should You Use Toggle Case?

  • ✔️ To fix text typed in the wrong case (e.g., Caps Lock mistakes)
  • ✔️ To reverse capitalization without retyping
  • ✔️ For stylistic or creative text effects
  • ✔️ When quickly experimenting with different formatting

Why Use This Tool?

  • ✔️ Instantly reverses text capitalization with one click
  • ✔️ Helps correct formatting errors fast
  • ✔️ Works across all devices — no installation needed
  • ✔️ Supports accented characters and multilingual text

How Is It Different from Alternating Case?

Toggle Case simply flips the current state of each letter. Alternating Case applies a fixed pattern (e.g., lowercase → uppercase → lowercase → ...), regardless of the input.

Toggle Case: tHiS iS A TeSt → ThIs Is a tEsT
Alternating Case: tHiS Is A TeSt

Pro Tip 💡

Toggle case is a lifesaver for recovering large blocks of text accidentally typed with Caps Lock on — especially when copying content from other sources.
