Online Number Randomizer
The number randomizer is a professional tool for conducting fair prize draws, lotteries, and contests. The algorithm uses the cryptographically secure random number generator Crypto.getRandomValues() to produce truly random results, eliminating any possibility of manipulation.
You can set any numeric range: from a simple 1–100 to complex step-based combinations. The randomizer is perfect for social media giveaways, subscriber contests, New Year lotteries, and corporate events.
Each participant gets equal chances of winning. Generation happens on the client side — the result cannot be predicted or faked. Free, no registration, no limits.
Features
- Number range: from 1 to 9,999,999
- Number step: configure the interval between values
- Number of results: from 1 to 100 at a time
- Zero-knowledge: data never leaves your device
- Cryptographically secure API — true randomness
- Instant copy and clear of results

Frequently Asked Questions
About the Number Randomizer
Are the generated numbers truly random?
Yes. We use Crypto.getRandomValues() — a cryptographically secure API that provides true randomness. No pseudo-random algorithms.
Can the results be manipulated?
No. Generation is performed on your device. The server does not participate in the process and cannot affect the result.
What is the maximum number range?
From 1 to 9,999,999. You can also set a step to get, for example, only even numbers.
How many numbers can be generated at once?
From 1 to 100 numbers per click. Each number is unique within a single generation.
