Generate random integers or decimals in any range, optionally without repeats and sorted; shuffle a pasted list to run a draw or pick names; or roll any number of dice with any number of sides. Every value comes from the browser’s cryptographic random source.

## How to use

1. Choose integers, decimals, shuffle or dice
2. Set the range and how many you need, or paste a list
3. Press “Generate again” for a new draw and copy the result

## Features

- crypto.getRandomValues, more uniform than Math.random
- Optional no-repeat integers for raffles and draws
- Decimals with a chosen number of places
- Shuffle a list and keep the first n for picking names or teams
- Dice with any count and any number of sides, plus the total

## FAQ

### How random are the results?

They come from the browser’s cryptographic generator, crypto.getRandomValues, which is uniformly distributed and unpredictable — fine for raffles and draws.

### How do I get numbers without repeats?

Tick “No repeats” under random integers. The range must contain at least as many integers as you asked for.

### Can I use it to pick names?

Yes. Switch to “Shuffle a list”, paste one name per line, set how many to keep and press Generate again for each new draw.

### Are the results stored anywhere?

No. Everything is generated locally and disappears when you reload the page.
