Random case generator

aLtErNaTiNg or random capitals, and a seed to get the same one again.

It runs entirely in this browser tab: what you type is never uploaded, and the tool makes no network request while it works. Open your browser's network panel and try it — nothing leaves the page. There is no sign-up and no limit beyond what your own browser can hold.

How to use it

  2. Adjust the settings beside it until the result is what you wanted.
  3. Copy the result, or save it as a file. The result updates as you type.

Questions

Is what I type uploaded anywhere?
No. This page carries the whole tool as WebAssembly and runs it on your own device. Nothing you type is sent anywhere.
Why does the result show as boxes on this page?
The two typefaces this interface ships do not have these characters — very few typefaces do. The result is correct and copying it gives the real characters; the tool says so whenever that is the case.
How long will the result be?
Longer than it looks, and the tool shows all three numbers: characters, letters as a person would count them, and bytes. A field's limit is in one of those three and never says which, which is why all three are here.
Can I get this result again later?
The settings travel in the page's address, after the #, so a link reproduces them exactly — and the fragment of an address is never sent to a server. Anything random takes a seed, so the same seed gives the same result every time.
