About this tool
The PixelForge UUID Generator creates universally unique identifiers (UUIDs) in versions 1 (time-based), 4 (random), and 5 (namespace-name hash) according to RFC 4122. UUIDs are widely used as primary keys in databases, session tokens, file names, API resource identifiers, and any context where a globally unique identifier is needed without centralised coordination. Generate single or bulk UUIDs with a single click.
Frequently Asked Questions
UUID v1 is time-based and incorporates the MAC address and timestamp. UUID v4 is randomly generated. UUID v5 is deterministically generated from a namespace and name using SHA-1 hashing — the same inputs always produce the same UUID.
UUID v4 uses cryptographically secure random bits from window.crypto.getRandomValues. The probability of two v4 UUIDs colliding is astronomically small.
Yes. Toggle the 'Remove hyphens' option for compact UUID output (32 hex characters without dashes).
Yes. Set the batch count to generate up to 1000 UUIDs in one operation. Copy all or download as a text file.
