Complete Guide: Bulk UUID / GUID Batch Generator
A UUID (Universally Unique Identifier) or GUID (Globally Unique Identifier) is a 128-bit time-ordered or random identifier used to identify database records, API tokens, user sessions, and microservices in distributed systems. Because UUIDs are globally unique without requiring a centralized database coordinator, they prevent primary key conflicts in modern cloud architectures.
💡 Version 4 (Random)
UUID v4 relies on 122 bits of pure cryptographic randomness. It is the most widely used UUID format for user IDs, transaction tokens, and random session keys.
🚀 Version 7 (Time-Ordered)
UUID v7 encodes a 48-bit Unix timestamp at the beginning of the ID, followed by random bits. This allows database B-tree indexes to insert records sequentially without page fragmentation.
Standard RFC 4122 & RFC 9562 Compliance
This online tool generates cryptographically secure v4 (random), time-sortable v7, and traditional v1 identifiers. Using the browser's native Web Cryptography API (crypto.getRandomValues), PakTools ensures all data is processed completely client-side in your local browser environment — guaranteeing 100% data privacy since no IDs are transmitted to external servers.
How to Use This Tool
- Set desired batch quantity (from 1 to 500 UUIDs).
- Select UUID version: v4 (Random), v1 (Timestamp), or v7 (Time-Ordered).
- Configure formatting options: Uppercase, Hyphens, Quotes, or JSON Array.
- Click Regenerate Batch to fetch fresh cryptographically secure UUIDs.
- Use 1-Click Copy or Export to TXT/JSON/CSV for developer workflows.

Frequently Asked Questions
What is a UUID / GUID?
UUID (Universally Unique Identifier) or GUID (Globally Unique Identifier) is a 128-bit number used to identify information in computer systems with virtually zero probability of duplication.
What is the difference between UUID v4 and v1?
UUID v4 is generated using pure cryptographic random numbers. UUID v1 is generated using a combination of system timestamp and MAC address to create time-sequential IDs.
What is UUID v7?
UUID v7 is the new RFC standard that combines a 48-bit Unix timestamp with random bits, producing time-sortable unique IDs ideal for database primary keys.
