GUID Generator

What is a GUID Generator?

A GUID Generator (also known as UUID Generator) is a tool that creates globally unique identifiers (GUIDs) used in software development, databases, and systems that require distinct identifiers. These IDs are typically 128-bit numbers formatted as strings and are nearly impossible to duplicate.

Why Use This GUID Generator?

• Ensure uniqueness across databases, files, tokens, and logs.
• Generate one or multiple UUIDs (v4) instantly, directly in your browser.
• Choose between regular randomness or secure UUID generation using crypto.randomUUID().
• Enable Uppercase formatting for better visual alignment or code consistency.

Secure UUID Option

By enabling the "Use secure UUID" option, this tool leverages the built-in crypto.randomUUID() method provided by modern browsers. This method generates cryptographically strong UUIDs with higher entropy and lower risk of collisions, ideal for security-sensitive applications. If your browser does not support it, a fallback UUID function based on Math.random() will be used.

Use Cases

• Assigning unique identifiers to users, sessions, or devices
• Generating primary keys for NoSQL or distributed databases
• Naming files or directories with guaranteed uniqueness
• Creating test data with bulk UUID generation
