What is UUID / GUID Generator?
Whether you're building a database, an app, or an API, you eventually need IDs that are guaranteed to be unique. That’s what a UUID (Universally Unique Identifier) does. It creates a string of characters that is so random, the chance of generating the same one twice is practically zero. This tool lets you generate secure, standard-compliant IDs instantly in your browser.
Best For
Fast browser-based workflows that do not require uploading files to a server.
Privacy
Your data stays on your device because processing happens locally in the browser.
Access
Free to use, no account required, and available at https://www.filemint.dev/tools/uuid-generator.

UUID Versions Explained: Choosing the Right Identifier for Your System
Not all UUIDs are created equal. Understand the technical differences between versions 1, 4, and 7 to optimize your database performance and uniqueness.
Privacy Architecture
This tool uses client-side WebAssembly to ensure your data never touches a server. Secure, fast, and privacy-focused by design.
Core Capabilities
- Generate v4 (Random), v1 (Time-based), or v5 (Name-based) UUIDs
- Bulk generation for up to 1,000 IDs at once
- Hyphenated or compact formatting options
- Uppercase or lowercase styling
- Built-in validator to check if an ID is valid
- High-security randomness using the Web Crypto API
- 100% Private — IDs are generated on your device
- Export your list as a clean text file
Why It Matters
- Unique Every Time: The math ensures you'll never run into a duplicate ID.
- Privacy: Since the IDs are generated locally, they never touch our servers.
- Standard Ready: Fully follows the official RFC 4122 specifications.
- Developer Approved: Perfect for primary keys, API tokens, and session IDs.
Quick Start Guide
Choose the version you need (v4 is the most common for apps).
Pick your formatting (hyphens usually make them easier to read).
Enter how many you need (1 to 1,000).
Hit 'Generate' and watch them appear instantly.
