Decode a ULID
Read the timestamp and randomness from a ULID.
💡 Versions 1, 6, and 7 (and ULIDs) embed a creation time, which is decoded above. Versions 4 are fully random and carry no timestamp. Everything is parsed in your browser.
ULID tips
A ULID packs a 48-bit millisecond timestamp into its first 10 Crockford base32 characters.
This tool decodes that timestamp to a date and splits out the 80 random bits.
ULIDs are case-insensitive and URL-safe — paste in any case.
Everything is decoded locally in your browser.
