About the Random Number Generator

Pick random numbers from any range — with no repeats, sorting, and instant statistics

What is it?

Our Random Number Generator instantly picks random numbers from any range you set, whether that's a classic 1-100, a quick 1-10 or 1-6, or anything up to 1000 and beyond. Use it for lottery and raffle draws, dice rolls and games, math practice, statistical sampling, coding test data, or any time you need to make a fair, random choice. You control the minimum, maximum, and how many numbers to draw, and you can switch off duplicates so every result comes out unique with no repeats. It works like an instant random number wheel — there's no list to type and nothing to install.

How it works?

Set your Minimum and Maximum to define the range, choose how many numbers to generate, and pick a format: Decimal, Binary, or Hexadecimal. Turn off Allow Duplicates for unique numbers with no repeats, or switch on Sort Results to order them from lowest to highest. Every draw uses a cryptographically secure random algorithm, so the numbers are unbiased, unpredictable, and impossible to rig. The tool also shows live statistics — average, minimum, maximum, and total sum — and lets you copy the results or download them as a text file.

Frequently Asked Questions

Everything you need to know about our random number generator

A random number generator (RNG) is a free online tool that instantly produces random numbers within a range you choose. Instead of guessing or rolling dice, you set a minimum and maximum and click once to get fair, unpredictable numbers. Ours picks each number with a cryptographically secure algorithm, so every value in your range has an equal chance of appearing.

Set the Minimum and Maximum fields to your range — enter 1 and 100 for a 1-100 draw, or use values like 1-10, 1-13, 1-24, 1-50, or 1-1000 just as easily. Then choose how many numbers you want and click Generate. The range accepts any whole numbers, including negatives, so you're never limited to fixed presets.

Yes. Turn off Allow Duplicates and every number in the batch will be unique, with no repeats — perfect for raffles, team draws, and lottery picks. Keep in mind the most unique numbers you can draw equals the size of your range (max − min + 1), so a 1-10 range returns at most 10 different numbers.

It works just like a random number wheel or picker — each click randomly selects a number, or a whole batch of numbers, for you. The difference is there's nothing to spin or set up first: type your range, hit Generate, and you get an instant, unbiased result every time.

In Excel or Google Sheets you can use =RANDBETWEEN(min, max); in Python use random.randint(min, max); in Java use the Random class or ThreadLocalRandom; and in JavaScript, Math.random(). Those work but mean writing a formula or code each time. Our free tool does the same job instantly in your browser — no spreadsheet and no scripts — and adds no-repeats, sorting, and live statistics.

Google's built-in random number generator gives you a quick single number between two values. Our tool does that too, but adds batch generation, a no-repeats mode, sorting, decimal/binary/hexadecimal formats, and instant statistics like average and sum — all on one page and free to use online.

Yes. Use the Number Format option to switch between Decimal (10), Binary (1010), and Hexadecimal (A). Binary is base-2 and hexadecimal is base-16, both widely used in programming, computer science, and digital electronics.

Set the Minimum to 1000 and the Maximum to 9999, then click Generate for a random 4-digit number. Adjust the range for other lengths — 100-999 for 3 digits, or 10000-99999 for 5 — and turn off Allow Duplicates if you need several unique codes at once.

Every number is produced with a cryptographically secure random algorithm using the browser's Web Crypto API, so results are genuinely unpredictable and can't be rigged or biased toward any value. That makes it fair for lotteries, raffles, giveaways, and any draw where impartiality matters.

Yes. Switch on Sort Results to order your numbers from lowest to highest, then copy the full list to your clipboard or download it as a text file. Each batch also shows live statistics — average, minimum, maximum, and total sum — so you can review the spread at a glance.
// Pro Tips

Tips & Best Practices

Pro tips to get the most out of this generator

Set the exact range

Use the Minimum and Maximum fields for any range — 1-100, 1-10, 1-1000, even negatives — instead of hunting for a preset.

Draw without repeats

Turn off Allow Duplicates for unique numbers — ideal for raffles, team draws, and lottery picks (capped at the size of your range).

Sort and read the spread

Enable Sort Results to order low-to-high, then check the live average, min, max, and sum before you copy or download.
