Random Number Generator Online — Free
Runs 100% in your browser — your files never leave your device.
Raffles, A/B choices, sampling, classroom picks, game nights — a fair random draw comes up more often than you think. Set a minimum and maximum, choose how many numbers to draw and whether repeats are allowed, and generate. The results stay on the page so you can copy them all at once.
How it works
- 1
Set the bounds
Enter the minimum and maximum — negative numbers work too.
- 2
Choose count and repeats
Pick how many numbers to draw, and whether duplicates are allowed.
- 3
Generate and copy
One click draws the numbers; another copies them all, comma-separated.
About this tool
What it generates
Random integers within any range you set — one at a time or in batches, with duplicates allowed or excluded. The randomness comes from your browser's generator, computed locally, with nothing logged or counted.
The uses
Draw winners from numbered entries, pick sample items for review, generate test values, roll for games, assign random orders, and any decision where a fair, unpredictable number is the requirement.
Fair means uniform
Every number in your range is equally likely — no weighting, no memory of previous draws. If you need non-uniform odds, that is a different mechanism; if you need fairness, uniformity is exactly what you get.
Frequently asked questions
Can it avoid repeating numbers in a batch?
Yes — enable unique draws and the batch excludes values it has already produced, sampling without replacement.
How fair is the randomness?
The browser's random generator provides uniform distribution across your range — every value equally likely, suitable for draws and games.
Can I use decimal ranges?
The generator produces integers within whole-number bounds; for decimals, generate a wider integer range and divide.
