Random Number Generator
Generate random numbers in any range — one at a time or in batches of up to 1,000, with or without duplicates. Perfect for sampling, games, raffles, and picking winners.
Range
Options
Numbers are produced with your browser's built-in Math.random — great for games, sampling, and raffles, but not suitable for passwords, keys, or any cryptographic use.
Frequently Asked Questions
- How do I generate random numbers?
- Enter a minimum and maximum value, choose how many numbers you want (1 to 1,000), and click Generate. The numbers appear instantly as chips you can copy all at once.
- Can the same number appear more than once?
- That is up to you. Leave "Allow duplicates" checked and each number is drawn independently, so repeats are possible. Uncheck it and every number in the batch is unique — which means the range must contain at least as many numbers as you ask for.
- Can I sort the generated numbers?
- Yes. Check "Sort results" and the batch is returned in ascending order instead of the random order it was drawn in.
- Are these numbers safe for passwords or cryptography?
- No. The tool uses your browser's Math.random, which is fine for games, sampling, raffles, and classroom exercises but is not cryptographically secure. For passwords or security keys, use a dedicated cryptographic generator.
- Is the random number generator free?
- Yes. It is completely free, requires no sign-up, and runs entirely in your browser — nothing you generate is sent to a server.
