UUID Generator

UUID Generator creates random version 4 universally unique identifiers in the standard 8-4-4-4-12 text form. Version and variant bits occupy fixed positions; the remaining random bits make accidental collisions extraordinarily unlikely, though not mathematically impossible.

Why use UUID Generator?

  • Work directly in your browser without uploading files for processing
  • Use clear controls to shape the result for the task at hand
  • Inspect independent lowercase UUID v4 strings before using or downloading it
  • Keep the source input unchanged while working on a new result

How to use UUID Generator

  1. Add the input: Choose how many UUID v4 values to generate.
  2. Set the options: Set the requested count within the interface limit and choose whether to copy one value or the full list.
  3. Run UUID Generator: Start the operation and review independent lowercase UUID v4 strings.
  4. Verify the result: Check the output against the intended destination before copying or downloading it.

Frequently Asked Questions

What does the 4 mean?

The version nibble identifies a randomly generated UUID.

Can UUID v4 collide?

It is theoretically possible but extraordinarily unlikely with proper randomness.

Can I decode a creation time?

No; version 4 does not embed one.
