UUVID4 Generator

UUIDv4 Generator – Generate Unique Identifiers Instantly | WebOfTools

WebOfTools offers a fast, secure, and developer-friendly UUIDv4 Generator that allows you to create universally unique identifiers (UUIDs) compliant with version 4 standards. Whether you’re working on software development, database indexing, distributed systems, or need a unique identifier for any use case, our UUIDv4 generator delivers collision-resistant results instantly – all in your browser.

What Is UUIDv4?

UUID stands for Universally Unique Identifier, and UUID version 4 (UUIDv4) is a specific format that uses random numbers to generate a 128-bit identifier. UUIDv4 ensures that the probability of duplicate identifiers is extremely low, making it ideal for modern applications requiring unique keys without centralized coordination. A typical UUIDv4 looks like this: e4eaaaf2-d142-11e1-b3e4-080027620cdd.

Why Use WebOfTools’ UUIDv4 Generator?

  • Completely Free: Generate UUIDv4 strings without registration or limits.
  • Secure & Random: Uses strong cryptographic random number generation in supported browsers.
  • One-Click Generation: Instantly create UUIDs with a single click.
  • Multiple UUIDs at Once: Generate bulk UUIDs for batch processing and development tasks.
  • Developer-Friendly: Ideal for APIs, software dev, databases, and distributed systems.
  • Privacy-First: No data is stored or transmitted – all generation happens client-side.

Common Use Cases for UUIDv4

The UUIDv4 standard is widely used across many industries and platforms. Some common applications include:

  • Database Keys: Use UUIDs as primary keys in relational and NoSQL databases.
  • Session Tokens: Securely identify user sessions in web applications.
  • API Resource Identifiers: Assign unique identifiers to resources in RESTful APIs.
  • Device Identifiers: Identify devices uniquely in IoT systems or hardware tracking.
  • File Naming: Avoid name collisions by using UUIDs for naming files or uploads.
  • Transaction IDs: Track orders, transactions, and logs with guaranteed uniqueness.

  • Standard Format: Universally recognized and supported across programming languages and platforms.

UUIDv4 Format and Structure

A UUIDv4 consists of 32 hexadecimal characters, displayed in five groups separated by hyphens, in the form:xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx

The “4” indicates version 4, and “y” represents a value in the range 8–b. This format ensures compliance with the UUID version 4 specification defined in RFC 4122.
