About UUID Generator

Introduction

The UUID Generator is a utility designed to generate random, cryptographically secure UUIDs (v4) in bulk. UUIDs (Universally Unique Identifiers) are standard in database design and software development, used to assign unique keys to records, users, and sessions.

This generator allows you to generate up to 100 UUIDs at once. You can customize formatting by toggling hyphens, uppercase lettering, or braces, running entirely client-side.

Key Features

Generate randomized UUIDs (v4) in bulk with these formatting options:

  • Cryptographically Secure (PRNG): Uses browser-native cryptographic APIs to generate truly random keys.
  • Bulk Key Generation: Generate up to 100 unique UUIDs in a single click.
  • Hyphen Options: Toggle standard hyphens (e.g. f81d4fae-7dec-11d0-a765-00a0c91e6bf6) on or off.
  • Braces and Casing: Wrap UUIDs in curly braces or convert them to uppercase formatting.

How to Use

Generate unique identifiers for your database records by following these simple steps:

  1. Set Quantity: Adjust the slider to set the number of UUIDs you want to generate.
  2. Select Options: Toggle settings to include hyphens, uppercase casing, or curly braces.
  3. Generate Identifiers: Click the "Generate UUIDs" button to generate the list.
  4. Copy to Clipboard: Click the "Copy All" button to copy the list of keys.

Benefits

This tool is perfect for database managers and programmers generating mock data. It works offline and runs client-side, ensuring your keys are never shared online.

Frequently Asked Questions

How do I generate UUIDs in bulk online?

Set the quantity slider in our UUID Generator, choose your formatting options (like uppercase or braces), and click generate to get unique IDs.

What is a UUID v4?

A UUID (Universally Unique Identifier) version 4 is a 128-bit identifier generated using random numbers. It is standard in database design.

Are the generated UUIDs cryptographically secure?

Yes, our tool uses browser-native cryptographic APIs (Crypto.randomUUID) to ensure generated keys are truly random and secure.

Can I generate UUIDs without hyphens?

Yes, you can uncheck the 'Include Hyphens' box to generate a compact 32-character hexadecimal string instead of the standard format.

Is there a limit to how many UUIDs I can generate?

You can generate up to 100 UUIDs in bulk in a single click, which is ideal for testing and database seed scripts.

Is this UUID generator free?

Yes, our UUID Generator is completely free, secure, and runs client-side inside your browser.

What is the probability of a UUID collision?

The probability of a collision in UUID v4 is virtually zero. It is so small that it is practically impossible to happen under normal usage.

Is my generated data secure and private?

Yes, all UUID generation occurs locally on your machine. No identifiers are sent or logged on our servers, protecting your secrets.

Can I generate UUIDs wrapped in curly braces?

Yes, check the 'Wrap in braces' option to generate UUIDs in Registry format (e.g. {f81d4fae-7dec-11d0-a765-00a0c91e6bf6}).

Does this UUID generator work offline?

Yes, once loaded, the tool runs entirely client-side, allowing you to generate identifiers without internet access.

Can I copy all generated UUIDs at once?

Yes, click the 'Copy All' button in the output panel to copy the entire list of generated keys directly to your clipboard.
