UUID Generator

What is a UUID Generator?

A UUID (Universally Unique Identifier) Generator is a tool that creates standardized 128-bit identifiers that are virtually guaranteed to be unique across space and time. UUIDs are used in software development, databases, and distributed systems to uniquely identify information without requiring central coordination.

Key Features:

• Generate RFC 4122 compliant UUIDs (version 4)
• Create multiple UUIDs at once
• Format options (with or without hyphens, uppercase/lowercase)
• Copy results with one click
• Free to use with no registration required
• Works entirely in your browser - no data sent to servers

UUID Versions:

• Version 1: Time-based UUID that uses the current timestamp and MAC address of the computer
• Version 4: Random UUID that uses random or pseudo-random numbers (most commonly used)
• Version 5: Name-based UUID that uses a namespace identifier and name string

Common Use Cases:

• Database primary keys
• Distributed systems where unique IDs are needed
• Session IDs in web applications
• Transaction IDs in financial systems
• File names and document identifiers
• Device identification in IoT systems

UUID Format:

A standard UUID is represented as 32 hexadecimal digits, displayed in 5 groups separated by hyphens in the form 8-4-4-4-12, for a total of 36 characters (including hyphens):

xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

How to Use:

1. Select the UUID version you want to generate
2. Choose how many UUIDs you want to create
3. Select your preferred format options
4. Click the "Generate UUIDs" button
5. Copy the results with the "Copy to Clipboard" button
