About this tool
Randomness comes from your browser's cryptographic random generator (crypto.getRandomValues), with a method that avoids bias, so each number has exactly the same chance. This makes it suitable for giveaways and fair draws.
Good to know: Results are not saved. For official prize draws, check the rules in your area, and consider recording the draw for transparency.
Free to use. Your inputs are processed in your browser and are not sent to our servers. Results are for general information; see the disclaimer.
Frequently asked questions
Is it truly random?
It uses your device's secure random generator, which is much better than the simple generators used in basic programs. Each value is equally likely.
How do I pick numbers with no repeats?
Tick No repeats. The generator will give each number only once, and tell you if the range is too small.
Can I use it for a giveaway?
Yes. Paste the entrants on separate lines in Pick from a list and choose how many winners you need.
