UUID Generator Generate cryptographically secure UUID v4 identifiers.

A UUID generator creates version 4 UUIDs — 128-bit identifiers that are practically unique across all systems without requiring a central registry. Developers and programmers use it to assign unique IDs to objects or records in their applications, solving the problem of ensuring data integrity by preventing duplicate identifiers. For instance, when generating multiple IDs at once, a specific challenge arises: creating a large number of unique identifiers quickly.

This tool solves that problem by allowing users to generate up to 1000 UUIDs at a time, with options to customize the output format. What makes it different is its ability to generate UUIDs in various formats, such as uppercase or without dashes, using features like the `uppercase` and `noDashes` checkboxes. It uses your browser's crypto.randomUUID() API for maximum security, ensuring that each generated UUID v4 has an astronomically low collision probability of 1 in 2^122.

It also provides a quantity input field, enabling users to specify the exact number of random UUIDs they need, making it a convenient GUID generator for those who want to generate UUID v4 online. By using this tool, developers can create unique identifiers quickly and easily, which is especially useful when working on projects that require generating multiple IDs at once, such as when creating test data or populating a database with sample records.
