UUID generator
Cryptographically random UUIDs.
Output
Output appears here as you type.
What this does
Uses `crypto.randomUUID()`, which draws from the platform CSPRNG. These are suitable for real identifiers, not just placeholders.
Limits
- Version 4 only, which is random rather than time-ordered. If you need sortable ids, you want UUIDv7 or ULID.
Is this private?
Yes, and you can check rather than take our word for it. Open your browser's network tab and run the tool: your file never appears in it, because there is no server to send it to. The whole site is static files.
