Random Generator
Random numbers, strings, bytes, dice and coins
How it works
Pick a mode — integers, decimals, strings, raw bytes, dice (NdM) or coin flips — set the parameters, and generate. All randomness comes from the browser's cryptographically secure generator, so results are unpredictable. Copy individual results or the whole batch.
Frequently asked
Is the randomness secure?
Yes — it uses crypto.getRandomValues, the browser's cryptographically secure random source, not Math.random.
Can I generate unique numbers?
Yes. In integer mode, enable ‘unique’ to draw without repetition within the requested range.
