UUID Generator
About Our UUID Generator
A UUID (Universally Unique Identifier) is a 128-bit number used to identify information in computer systems. Our generator provides a reliable way to create various versions of UUIDs for your development needs, from database keys to unique session identifiers. All generation is performed securely in your browser.
Core Features
- Multiple Versions: Generate Version 1 (timestamp-based), Version 4 (random), and the new Version 7 (Unix Epoch) UUIDs.
- GUID Support: Instantly create GUIDs (Globally Unique Identifiers) formatted for use in Microsoft applications.
- Bulk Generation: Create up to 1,000 UUIDs at once for testing or database seeding.
- Secure & Local: All UUIDs are generated on your device. Nothing is ever sent to a server.
Frequently Asked Questions (FAQ)
What is the difference between UUID and GUID?
Functionally, they are the same. GUID is Microsoft`s implementation of the UUID standard. The only practical difference is that GUIDs are sometimes displayed with curly braces `{}`.
Which version should I use?
Version 4 is the most common and is ideal for most use cases where randomness is key. Version 1 is based on a timestamp and MAC address, making it predictable. Version 7 is a new standard that combines a timestamp with random data, making it sortable and ideal for database primary keys.
