Decode a ULID

Read the timestamp and randomness from a ULID.

ログイン不要

💡 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.
