🔒 Everything runs 100% in your browser. Your files and input are never uploaded to any server.
This tool lets you roll dice, flip coins, and draw random numbers within a range right in your browser. Every value is generated with a cryptographic random number generator for even results, and nothing is ever sent to a server.
How to use
- Choose the feature you want — dice, coin, or range random — from the tabs at the top.
- For dice, enter the count and number of sides; for coins, the count; for range random, the minimum, maximum, and how many to draw.
- Press Roll / Flip / Draw to see each result along with the sum, average, and ratio.
- Use the Copy Result button to copy the drawn values and share them as-is.
FAQ
- Are the results really fair?
- We use the browser's built-in crypto.getRandomValues cryptographic randomness, evened out with rejection sampling so no value is favored. It's less biased than the usual Math.random.
- Can I draw without duplicates?
- Turn on 'Draw without duplicates' in the Range Random tab to get non-overlapping values, just like a lottery or number draw. If you request more numbers than the range allows, only as many as the range size are drawn.
- Are the results sent anywhere?
- No. All random generation and calculation happen entirely within your browser and are never sent to or stored on a server. That said, don't use this for official draws or anything with legal weight — treat the results as a reference only.
