About Alternating Case Converter
An alternating case converter swaps between small and capital letters one letter at a time, starting with a small one, which gives the "mocking" style you see in memes. Paste hello world and you get hElLo WoRlD. It is free, needs no sign-up and runs in your browser, so nothing you enter is uploaded.
The alternation counts letters only, so spaces, digits and punctuation do not break the rhythm. Because the pattern follows the letters, the same text always gives the same result.
It is for fun, not for anything you want people to read quickly. Screen readers and many people find alternating text hard to follow, so avoid it for real content.
