this is fine

could become

tHIs iS FiNe

or THis is fInE the next time. Every run is different.

Ways people use it

Randomness comes from your browser's secure random number generator, so the pattern cannot be predicted. For a neat, regular pattern instead, try the alternating case generator.

Keep it readable

Random case is fun in small doses but tiring to read in long passages, and screen readers may struggle with it. Keep it for short jokes and captions, not for information people need.

Frequently asked questions

How is random case different from alternating case?

Alternating case follows a strict pattern: lower, upper, lower, upper. Random case has no pattern at all, so it looks messier and more chaotic, like rAnDOm CasE.

Can I get a different result?

Yes. Click the "rAnDOm CasE" button again, or type another letter. Each time the letters are mixed in a new way.

Do numbers and emoji change?

No. Only letters are affected. Numbers, spaces, punctuation and emoji stay as they are.

Why would developers use random case?

It is a quick way to check that a search box, login form or database lookup ignores capital letters. If "eMaIL@ExaMple.cOm" still finds the right account, case handling works.
