Decoded locally in your browser by parsing the 64-bit value with BigInt. Nothing is generated or sent anywhere — your Snowflake ID stays only on this page.

Read a Snowflake's embedded timestamp and bits

A Snowflake packs a millisecond timestamp into its top 42 bits (id >> 22), followed by a 10-bit machine field and a 12-bit sequence. Because the timestamp is relative to a service epoch, pick Discord (1420070400000), Twitter/X (1288834974657), or a custom epoch. Discord further splits the machine field into a 5-bit worker and 5-bit process ID. This tool only reads the bits already in the identifier; to create one, use the Snowflake ID generator.
