Generate version 4 UUIDs (Universally Unique Identifiers). Create single or bulk UUIDs and download them as a text file. Perfect for database keys, session identifiers, and distributed systems.
A Universally Unique Identifier is a 128-bit label used for information in computer systems. The generation algorithm ensures uniqueness across space and time.
Generate bulk UUIDs to see them here and download as text file.
Database primary keys, API identifiers, session tokens, transaction IDs, and distributed systems where unique IDs must be generated independently.
Randomly generated UUID. 6 bits are used for version and variant, leaving 122 random bits. Total unique combinations: 2^122 (5.3×10^36).
Bulk generate up to 1000 UUIDs instantly. Each UUID is cryptographically random using PHP's mt_rand() which is sufficient for non-security purposes.
Downloaded .txt file contains one UUID per line. Compatible with Excel, databases, and most programming languages for batch importing.
Probability of collision is extremely low. You can generate UUIDs on different machines without coordination and be confident they are unique.
