UUID 產生器

使用方法

1. Choose v4 (random) or v7 (time-ordered, sortable) from the version toggle。
2. Set the count between 1 and 20。
3. Click "Generate" to produce fresh UUIDs using the browser's Web Crypto API。
4. Copy all generated UUIDs at once with the copy button。

範例

• Selecting v4 and count 5 produces five random UUIDs like 3f2504e0-4f89-41d3-9a0c-0305e82c3301 — no two runs produce the same set。
• Selecting v7 and count 3 produces time-ordered UUIDs whose first 12 hex digits encode the current millisecond timestamp, making them naturally sortable。
