Generate cryptographically secure RFC 4122 Version 4 UUIDs. Generate single or bulk (up to 100 at a time), with uppercase or hyphen toggles.
The interactive UUID / GUID Generator workspace loads in your browser. Read the practical guide and processing details below.
No software installation or registration needed. Works smoothly on all devices.
Choose how many UUIDs you need.
Toggle hyphens or uppercase.
Copy all generated UUIDs at once.
Generate identifiers for test records, mock data or an application workflow that needs a random UUID.
Developer utilities help inspect and transform data during development. Always distinguish readable output from validated or trusted output: formatting JSON does not validate a business schema, decoding a token does not verify a signature, and a generated snippet still needs to be tested in the receiving application.
Choose the count and formatting, then copy the generated values. Confirm whether the receiving application expects hyphens or uppercase characters.
Use UUID / GUID Generator on ToolBexa as one step in your workflow, then inspect the exported result before uploading or sharing it. If a receiving website gives a format, dimension or input rule, use that requirement rather than a convenient default.
Random identifiers are not passwords, authorization tokens or a replacement for an application’s data-integrity checks. Use the format your system requires.
The core operation runs in your browser. Downloaded results remain on your device, and page preferences may be saved in browser storage. Check the Privacy Policy for server logs, external resources and other site features.
The probability of a collision in v4 UUID is virtually zero.
