Frequently Asked Questions
How are Version 4 UUIDs generated in this tool?
When supported by your browser, this tool calls the native Web Crypto API method crypto.randomUUID() (with a standard v4 pattern fallback) locally in your browser.
Is there any difference between a UUID and a GUID?
They are 128-bit identifiers displayed as 32 hexadecimal digits in 8-4-4-4-12 format. 'UUID' is the IETF/RFC term, while 'GUID' (Globally Unique Identifier) is commonly used in Microsoft tools (which often wrap the value in curly braces {}).
How many UUIDs can I generate and export at once?
You can generate between 1 and 100 UUIDs per batch and either copy them to your clipboard or download them as a newline-separated .txt file.
