Is the Random Number Generator free?

Yes — the Random Number Generator is completely free, with no account, subscription, signup, or usage limits.

Is my data uploaded or stored?

No. The Random Number Generator processes everything locally in your browser. Your input is never uploaded, saved, or shared with any server.

Does the Random Number Generator work offline?

Yes. Once the page has finished loading, the Random Number Generator works without an internet connection.

Which browsers does the Random Number Generator work in?

The Random Number Generator works in all modern browsers, including Chrome, Firefox, Safari, and Edge — no plugins or extensions needed.

Is the free Random Number Generator truly random?

It uses Math.random() which is a pseudo-random number generator (PRNG) — sufficient for games, simulations, and data generation, but not for cryptographic security. Use the Strong Password Generator for security-critical randomness.

Can I generate the same set of numbers twice?

Not reliably — the generator is stateless and non-seeded. Each click of Generate produces an independently random set.

What is the Random Number Generator?

The free Random Number Generator produces one or more random numbers with full control: set the Min and Max bounds, choose a Count, specify the number of Decimal places, and toggle Unique (no repeats) and Sorted (ascending order). It is faster than rolling dice and more flexible than spreadsheet functions for producing random data.

→ Generate random lottery numbers or raffle picks from a specified range.
→ Create random test data within defined numeric bounds for software testing.
→ Pick a random subset of unique numbers from a large pool.
→ Simulate dice rolls or random events for games or decision-making.
→ Produce random decimal values for statistical sampling or simulations.

How to Use the Random Number Generator

1 Set the Min and Max fields to define the numeric range.
2 Set the Count field to how many random numbers you need.
3 Choose Decimal places (0 for integers, 1–4 for decimal output).
4 Enable Unique to ensure no number appears twice in the results.
5 Enable Sorted to receive the numbers in ascending order.
6 Click Generate — the results appear instantly and can be copied with the Copy button.
