UUID generator (version 4)
Generate cryptographically random version-4 UUIDs, one at a time or in batches, with one-tap copy.
What this does
Press Generate for fresh version-4 UUIDs — 128-bit identifiers drawn from your browser's cryptographic random source (crypto.getRandomValues), the proper way, not Math.random. Choose a batch of 1, 5 or 10, and Copy puts the whole list on your clipboard.
Notes
Version 4 is the random flavour: 122 of its 128 bits are random, which is why two generated UUIDs are, for practical purposes, never the same — the reasoning (and when not to use a random UUID) is in the UUID guide. Generated on your device, transmitted nowhere.
