Generate random UUID v4 identifiers individually or in batches of up to 100. Copy one ID per line, free and entirely in your browser.
● Your files stay yoursChoose 1–100. Each new batch replaces the previous result.
Copy becomes available when a result is ready. Editing inputs or options clears the previous result.
Choose how many identifiers you need and select Generate UUIDs. Copy result copies the whole batch, with one UUID per line and no extra final newline. Generate again for a new batch. Changing the quantity clears the old result; Clear removes it without changing your quantity.
A UUID is a 128-bit identifier commonly used for records and test data. Version 4 uses random values, rather than a timestamp or name. Output has 36 characters: lowercase hexadecimal digits and hyphens in an 8-4-4-4-12 layout, for example 550e8400-e29b-41d4-a716-446655440000 (illustration only). This tool uses your browser’s secure random UUID generator and requires HTTPS and browser support. IDs are not stored or sent to a server. Random generation makes collisions extremely unlikely but does not guarantee global uniqueness; this tool does not check your existing records. It generates v4 only, not time-ordered v7 or name-based UUIDs.
