UUID & GUID Generator

Generate UUID v4 or v7 in your browser. Create up to 1,000 GUIDs at once, copy one ID per line or download the list. No account or server-side generation.

How to generate UUIDs or GUIDs

  1. Choose v4 for random identifiers or v7 for identifiers with a time-ordered prefix.
  2. Set the count from 1 to 1,000 and generate a fresh batch in your browser.
  3. Copy the newline-separated IDs or download the list. Do not reuse the fixed examples shown below.

Working with UUID & GUID Generator

UUID v4 uses cryptographically secure randomness. UUID v7 includes a millisecond timestamp and is useful for time-ordered identifiers. UUID and GUID commonly refer to the same identifier format; neither is a replacement for an access-control secret.

Questions about UUID & GUID Generator

Should I use UUID v4 or v7?

v4 is random and does not encode a creation time. v7 starts with a Unix millisecond timestamp, making it useful for time-oriented ordering. Choose the version supported by your database or application; v7 exposes approximate generation time.

Are GUID and UUID the same thing?

GUID and UUID commonly refer to the same 128-bit identifier. This tool outputs lowercase hexadecimal in the usual 8-4-4-4-12 grouping, with hyphens and no braces. The version digit is 4 or 7.

Can I generate UUIDs in bulk, and are they guaranteed unique?

Generate 1 to 1,000 per batch, one per line, then copy or download them. Proper random generation makes collisions extremely unlikely, not impossible. Keep a uniqueness constraint when identifiers become database keys.

Can I use a UUID as a password or access token?

Treat these as identifiers, not credentials. Knowing an ID must not grant access by itself. v7 also reveals time information. Use a purpose-built secret generator and proper authorization for passwords, sessions and access tokens.

Are my files, tokens or text uploaded?
