Key Features

RFC 4122 Compliant

UUID v4 uses crypto.randomUUID() per the spec. v7 is the new time-sortable standard.

Bulk Generation

Generate up to 100 UUIDs at once. Export as plain list, JSON array, or SQL VALUES.

Instant & Free

No sign-up, no limits. Regenerate as many times as needed.

How to Use

  1. 1

    Choose UUID version

    Select v4 (fully random) or v7 (time-sortable, recommended for database primary keys).

  2. 2

    Set quantity

    Enter how many UUIDs to generate, from 1 to 100.

  3. 3

    Choose output format

    Select List (one per line), JSON array, or SQL VALUES format.

  4. 4

    Click Generate

    UUIDs are generated instantly using the browser's crypto API.

  5. 5

    Copy all

    Click the copy button to copy all generated UUIDs to your clipboard.

Frequently Asked Questions

Is the UUID generator free?+
Yes, completely free with no sign-up and no limits on how many UUIDs you generate.
What is the difference between UUID v4 and v7?+
UUID v4 is fully random — great for general use. UUID v7 embeds a Unix timestamp in the first 48 bits, making them monotonically sortable by creation time. v7 is better for database primary keys because sequential IDs reduce index fragmentation.
Are these UUIDs truly unique?+
UUID v4 uses 122 bits of randomness, giving approximately 5.3×10³⁶ possible values. The probability of two random UUIDs being identical is astronomically small — for practical purposes, they are guaranteed unique.
