About UUIDs (Version 4)
A Universally Unique Identifier (UUID) or Globally Unique Identifier (GUID) is a 128-bit number used to identify information in computer systems. The UUIDs generated above are Version 4, meaning they are randomly generated.
How it works
- Consists of 32 hexadecimal digits separated by hyphens (e.g.,
xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx). - In Version 4 UUIDs, the 13th character is always
4, and the 17th character is8,9,A, orB. - With 122 random bits, the probability of generating a duplicate UUID is astronomically small (practically zero).

Frequently Asked Questions
The UUID/GUID Generator is a utility designed to automate, format, encode, or decode technical data, speeding up the global software development workflow and reducing manual errors.
Yes. Security is critical for developers. The UUID/GUID Generator processes everything locally in your browser via JavaScript. We never transmit your code, tokens, or strings to external servers.
The UUID/GUID Generator is optimized for standard use cases. While it handles large strings efficiently, extremely massive datasets (gigabytes in size) might slow down your browser as the processing is client-side.
Yes, the UUID/GUID Generator adheres to globally accepted programming standards and best practices (like standard JSON specifications or common encoding algorithms) to ensure compatibility across all systems.
Because the logic executes entirely on the client side, once the UUID/GUID Generator page is loaded, it generally remains functional even if you lose your internet connection.
The UUID/GUID Generator requires zero installation, configuration, or system resources. It is globally accessible instantly from any device, making it perfect for quick tasks without launching a heavy IDE.
No! Because the computations happen on your own machine, there are no artificial API rate limits. You can use the UUID/GUID Generator as frequently as you need.
