About this tool

Generate cryptographically random tokens in your browser using crypto.getRandomValues, in your choice of format and length.

Are these tokens secure?

Yes — they use the browser's cryptographically secure random number generator, and nothing leaves your device.

What do the formats mean?

Hex uses 0-9a-f, base62 uses letters and digits, and base64url uses URL-safe Base64 without padding.
