Generate UUIDs

Generate as many version 4 UUIDs as you need and copy them one by one or all together. They come from the browser's cryptographic random number generator, and the version and variant bits are set by the platform rather than assembled by hand — which is what hand-rolled generators tend to get wrong, producing strings that look like v4 UUIDs and are not.

This tool runs entirely on your device. Nothing you type here is uploaded, logged or stored.
