Random Number Generator 1-100 — Free Online RNG

Introduction

A random number generator 1-100 is one of the most useful everyday tools on the internet — and Trencada's free Random Number Generator goes further, letting you pick truly random numbers in any range you choose. Whether you're drawing raffle winners, rolling virtual dice, shuffling teams, or making a tough decision, this free online RNG delivers instant, unbiased results with no signup and no downloads. Everything runs entirely in your browser using your device's built-in random number engine, so your picks are generated locally — nothing is uploaded, stored, or tracked.

How to Use

1. Enter your Min and Max values to define the range (for example, 1 to 100).
2. Set the Quantity — how many random numbers you want (up to 1000 at once).
3. Tick Allow duplicates for repeats, like dice rolls — or untick it for unique picks, like drawing raffle winners.
4. Optionally tick Sort results to list your numbers in ascending order.
5. Press Generate and watch the quick rolling animation, then hit Copy Results to paste your numbers anywhere.

Frequently Asked Questions (FAQ)

• Is the Random Number Generator truly random? It uses your browser's built-in random number engine (Math.random), which is more than random enough for games, raffles, giveaways, and everyday decisions. It is not designed for cryptography or regulated lotteries.
• Can I generate numbers without duplicates? Yes — untick "Allow duplicates" and the tool will only return unique numbers. If your quantity is larger than the range allows, you'll get a clear inline message explaining the fix.
• What is the largest range I can use? Any integer range works, from small (1–6 for dice) up to millions. Quantity is capped at 1000 numbers per generation to keep the page fast.
• Do I need to create an account? No. Like all Trencada tools, it works instantly with no signup or login.
• Is my data private? Yes. The tool runs entirely in your browser — no numbers, settings, or personal data are uploaded anywhere.
