UUID Generator
ReadyGenerate a standard UUID v4 identifier. Every button press creates a new unique value. It uses the browser cryptographic number generator and sends no request to a server.
All tools are free to use. File size and processing limits may vary by tool.
How to generate?
Press the button and copy the value; use it for database keys, file names and request traces. Collision odds are negligible, yet verify primary key uniqueness on critical tables.
Browser tools keep files on your device. Advanced document tools upload files for temporary server processing; the tool shows this before upload. Web lookups send queries to the server and public lookup services.
UUID Generator
Database rows need unique identifiers that never collide. This tool creates version 4 UUIDs with one click entirely in your browser. Label test values so they never mix with real identifiers.
