UUID Generator

Generate random UUIDs (v4 and v7) in bulk. Copy individual IDs or entire lists with one click.

Loading...
1. Select the UUID version you need - v4 (random) or v7 (time-ordered). 2. Choose between single generation or bulk mode for up to 1000 UUIDs at once. 3. Optionally select uppercase or lowercase formatting for the output. 4. Click "Generate" to create the UUIDs instantly. 5. Copy individual UUIDs by clicking the copy icon, or copy the entire list with the "Copy All" button.

About This Tool

The UUID Generator creates universally unique identifiers in both v4 (random) and v7 (time-ordered) formats. Whether you need a single ID for a database record or a batch of 1000 UUIDs for a data migration, this tool generates them instantly and lets you copy them with a single click.

UUID v4 uses 122 bits of cryptographically secure randomness, producing IDs that are practically guaranteed to be unique across all systems worldwide without any coordination. UUID v7 embeds a Unix timestamp in the most significant bits, creating IDs that are both unique and naturally sortable by creation time - a significant advantage for database indexing and distributed systems.

Generate individual UUIDs or switch to bulk mode to create up to 1000 at once. Copy the entire list or individual IDs to your clipboard. The tool formats output with one UUID per line, ready to paste into code, configuration files, or database scripts. Both uppercase and lowercase formatting options are available.

Frequently Asked Questions

A UUID (Universally Unique Identifier) is a 128-bit label used to uniquely identify information in computer systems. The format is a 36-character string like "550e8400-e29b-41d4-a716-446655440000". UUIDs are designed to be unique without requiring a central authority.
UUID v4 is generated entirely from random numbers, making each ID completely unpredictable. UUID v7 is time-ordered, embedding a timestamp so that IDs generated later are lexicographically greater - this makes v7 ideal for database primary keys where sort order matters.
Yes. You can generate up to 1000 UUIDs at once in bulk mode. Copy the entire list to your clipboard with a single click, or copy individual UUIDs as needed.
Practically yes. UUID v4 has 122 bits of randomness, giving over 5 undecillion possible values. The probability of generating a duplicate is astronomically small - you would need to generate a billion UUIDs per second for about 85 years before a 50% chance of one collision.
Both tools generate UUIDs using the same underlying algorithms. This version is in the Generators category for quick access alongside other randomizer tools. The Developer Tools version includes additional features like UUID validation and parsing.
