How do I generate a random number?

Enter the lowest and highest number you want, choose how many numbers to generate, then press Generate. For a quick one, use a preset such as 1 to 10 or 1 to 100.

How do I get a random number between 1 and 100?

Press the “1 to 100” preset and then Generate. Both 1 and 100 can come up, and every number in between has the same chance.

Can I generate numbers without repeats?

Yes. Tick “No repeats” and choose how many numbers you want. Each number appears at most once, which suits raffles, lottery-style picks and assigning turns. The count cannot be larger than the range.

Is this a true random number generator?

It uses your browser’s cryptographically secure random generator, which is seeded from your device’s unpredictable system entropy. That is far better than a simple formula and is fine for games, giveaways and decisions. A hardware source is only needed for specialised security work.

What is the difference between pseudo-random and true random?

Pseudo-random numbers come from a formula that starts from a seed, so the sequence is repeatable. Cryptographic generators like the one in your browser are unpredictable in practice. True random numbers come from physical noise such as radioactive decay or atmospheric noise.

Can it make decimal numbers?

Yes. Choose 1 to 6 decimal places and it generates numbers like 0.37 or 12.845 between your minimum and maximum.

Can I use it to pick a giveaway winner?

Yes. Number your entries from 1 to the total, then generate one number with no repeats for each prize. For picking from a list of names, the Random Name Picker is easier.

Can I use it for the lottery?

You can generate numbers for fun, but a lottery draw is random, so generated numbers are no more likely to win than any others. Never spend money you cannot afford to lose.

How many numbers can I generate at once?

Up to 1,000 numbers, in a range between -1,000,000,000 and 1,000,000,000. You can sort the list and copy it in one click.

Is it free? Are my numbers stored?

It is free with no sign-up. Numbers are generated in your browser and are not stored or sent anywhere.
