About This Tool
The UUID Generator creates version 4 UUIDs for development, testing, records, and distributed workflows. A UUID is useful when an identifier should be very unlikely to collide across systems. This tool can generate one UUID or a batch of many values, then copy a single item or the whole list.
ToolPool runs this utility in your browser, so your input stays on your device and is not uploaded to our server.
How To Use This Tool
- 1Choose whether you need one UUID or a batch.
- 2Set a quantity for multiple UUIDs.
- 3Copy one value or copy all generated values as newline-separated text.
Benefits
Common Use Cases

- Generating request IDs for debugging samples.
- Preparing unique keys for mock JSON objects.
- Creating identifiers for local scripts and prototypes.
Workflow Tips
UUID Generator is designed for quick browser work, but it is still worth reviewing the result before you use it in a live project, client document, public page, or production workflow. Keep an original copy of important source material, compare the output with what you expected, and repeat the task with slightly different settings when quality, formatting, or accuracy matters.
For larger workflows, pair this page with Random Data Generator, JSON Formatter, URL Encoder / Decoder, Base64 Encoder, JSON Validator. Moving between related utilities can save time when you need to clean source data, prepare web assets, create supporting IDs, check calculations, or package output for another system. Internal links also make it easier to stay in one private workspace instead of jumping between several single-purpose sites.
The local processing model helps protect sensitive content because ToolPool does not need to receive your files, text, or form values to complete the task. Good privacy habits still matter after the result leaves the page: avoid pasting unnecessary secrets, check downloaded files before sharing them, and clear the workspace when you are finished on a shared computer.
