UUID Inspector

Paste any UUID to decode its internal structure. The inspector shows the version, variant, raw bytes, and extracts timestamps for time-based UUIDs.

v1 / v6 — timestamp (100-ns intervals since 1582), clock sequence, and MAC address. v7 — Unix timestamp in milliseconds.

v3 / v5 — hash-based, the version and variant are detected but no embedded data can be extracted. v4 — random, no embedded information.
