Pro Tip: Formatting options apply to the UUID string. Base64/Base64URL are derived from the 16-byte UUID and do not include braces/hyphens.
Tips & How to Use
- 1. Set quantity (1–1000) and choose formatting: hyphens, {} braces, UPPERCASE, quotes, and comma-separated.
- 2. Pick encodings to additionally compute Base64 (raw 16-byte UUID), Base64URL (RFC 7515, no padding), or URL-encode the string form.
- 3. Click Generate. Use Copy for the list or Download as a .txt file.
- 4. Use Share Link to keep your options (quantity & toggles) prefilled.
