- Uniqueness： Theoretically very low probability of duplication worldwide. -Standardised Standardised： Compliant with RFC 4122, compatible with many systems and programming languages. -Standardised Centralised Generation： Generate unique IDs without relying on a central server. How to use this tool?
1. Generate a single GUID： Click the "Generate" button to get a standard formatted GUID. 2. Batch Generation： Enter the number of GUIDs to be generated (e.g. 10, 100, etc.) and the system will quickly output a list. 3. Copy Result： Support one-click copy single or all GUIDs, easy to use directly in code or database. Application Scenarios
- Database primary key or unique identification fields - Distributed system node identification - Software licence key generation - Log tracking and event IDs Frequently Asked Questions
Q：Will the GUID be duplicated? A: Theoretically possible, but the actual probability is very low (about 1 in 2^122) and can be considered unique. Q: Do I need to be connected to the Internet to use it? A: The tool is generated based on the browser's local algorithm, no network request is required and data privacy is guaranteed.
