About the UUID Generator

UUIDs and ULIDs are unique identifiers you can create anywhere without a central database. Generate up to 1,000 at once as random UUID v4, time-ordered UUID v7 or compact ULIDs, with options for uppercase and no dashes.

When to use it

  • Creating primary keys for databases and records
  • Generating test data and fixture IDs
  • Naming files and uploads uniquely
  • Creating idempotency keys for API calls

Tips for the best results

  • UUID v7 and ULID sort by creation time, which keeps database indexes efficient
  • UUID v4 is fully random — best when you don’t want IDs to reveal time
  • ULIDs are shorter and case-insensitive, handy in URLs

How to use the UUID Generator

  1. Paste your input into the UUID Generator.
  2. The output is generated instantly in your browser.
  3. Copy or download the result.
