Choose UUID version 1, 4, 6 or 7 and a quantity from 1 to 1,000, then generate your identifiers locally. Use lowercase or uppercase, include or remove hyphens, and optionally add braces. Formatting preserves the generated identifiers. Copy individual UUIDs or the whole batch, or download TXT and CSV files.
