Random Number Generator
Generate highly secure random numbers instantly. Define your range, generate in bulk, and sort your results with a single click.
How to Use
- Enter your desired Minimum and Maximum range (e.g., 1 to 100).
- If you need multiple numbers, change the Quantity field.
- Choose whether to allow duplicates and how you want the results sorted.
- Click Generate Numbers. The result will appear instantly.
Features
Crypto-Secure

Use Cases
- Lotteries & Giveaways: Pick a truly random winning ticket number.

- Passwords & Security: Generate random PIN codes or numeric tokens.
How It Works (Security)
Unlike basic random number generators that rely on the predictable Math.random() function, this tool utilizes the modern browser crypto.getRandomValues() API. This provides cryptographically secure pseudorandom number generation (CSPRNG), making it impossible to predict the outcome and perfectly safe for sensitive use cases like cryptographic key generation or high-stakes giveaways.
Complete Your Toolkit
If you need alphabetic strings instead of numbers, use the Random String Generator. For generating secure login credentials, try the Password Generator. Or, if you are looking for globally unique identifiers, use our UUID Generator.
Frequently Asked Questions
Can I generate negative numbers?
Yes! You can enter negative values in the Minimum or Maximum fields (e.g., -50 to 50).
What happens if I disable duplicates?
The tool will ensure every number in the output list is unique. Note that you cannot request more unique numbers than the range allows (e.g., you can't ask for 15 unique numbers between 1 and 10).
Is this truly random?
It uses Cryptographically Secure Pseudorandom Number Generation (CSPRNG) via your browser's Web Crypto API, which is as close to "true random" as a standard computer can achieve without specialized hardware.
Are the generated numbers saved anywhere?
No. Generation happens 100% locally in your web browser. Nothing is sent to our servers.
Is it free?
Yes, 100% free with no limits.
