How toggle case works

Toggle case alternates letter case starting with uppercase: hello world becomes HeLlO WoRlD. Like alternating case, only letters advance the pattern; spaces and punctuation are copied as-is.

Toggle vs alternating vs inverse

Toggle case starts uppercase (HeLlO), alternating case starts lowercase (hElLo), and inverse case swaps each letter individually (hELLO). Pick the pattern that matches the look you want.

Toggle Case FAQs

What is toggle case?
A stylized pattern where letters alternate between upper and lower case, starting with uppercase: HeLlO WoRlD. It is used for playful captions and meme text.
How is it different from alternating case?
Only the starting letter differs. Toggle case starts uppercase (AlTeRnAtInG); alternating case starts lowercase (aLtErNaTiNg).
How is it different from inverse case?
Inverse case swaps each letter's existing case (Hello becomes hELLO). Toggle case ignores the original case and forces the alternating pattern.
Does punctuation break the pattern?
No. Punctuation, spaces, and numbers are copied unchanged and the alternation continues across them, keeping the rhythm consistent.
Is my text sent to a server?
No. The conversion runs entirely in your browser with JavaScript. Nothing you paste ever leaves your device.
