Generate random numbers with custom ranges, unique value options, and sorting. Perfect for classrooms, raffles, test data, and more.
Set any min and max values
Generate multiple numbers at once
No duplicates option available
Paste your list above to sort, clean, and transform. All processing happens in your browser — your data never leaves your device.
Everything you need to generate random numbers for classrooms, raffles, testing, and data generation.
Set any minimum and maximum values for your random numbers. Generate dice rolls (1-6), lottery numbers (1-49), or any custom range you need.
Generate hundreds or thousands of random numbers at once. Perfect for creating test datasets, simulation inputs, or bulk random selections.
Enable unique-only mode to ensure no duplicates in your generated set. Essential for raffles, random sampling without replacement, and fair selections.
Sort generated numbers in ascending or descending order, or keep them randomly ordered. Makes results easier to read and analyze.
Uses the Web Crypto API for cryptographically strong random numbers when available, ensuring high-quality randomness for your applications.
All generation happens locally in your browser. No numbers are sent to any server, ensuring complete privacy for your random data.

Randomly select students for participation, create group assignments, or generate quiz question orders for fair assessments.
Generate winner numbers for contests, door prizes, or promotional giveaways with guaranteed unique selections.
Create random events, loot drops, enemy spawns, or any game mechanic requiring unpredictable number generation.
Populate databases, test forms, or stress-test applications with large quantities of random numerical data.
Select random samples from numbered populations for surveys, quality control, or research studies.
Fairly distribute team members, assign locker numbers, or allocate resources using random number selection.
Computer-generated random numbers are technically "pseudorandom" - they're produced by algorithms that create sequences appearing random but are actually deterministic given the same starting conditions (seed). However, modern browsers provide access to the Web Crypto API, which uses hardware entropy sources to generate cryptographically secure random values.
For everyday applications like games, classroom activities, and test data, pseudorandom numbers are more than adequate. They pass statistical randomness tests and are suitable for most practical purposes. Our generator leverages the strongest randomness source available in your browser.
The uniform distribution ensures each number in your specified range has an equal probability of being selected. When you enable unique-only mode, the generator uses rejection sampling to eliminate duplicates while maintaining uniform distribution across remaining possibilities.
Our random number generator uses your browser's built-in cryptographically secure random number generator (crypto.getRandomValues) when available, falling back to Math.random() for basic randomness. This ensures high-quality random numbers suitable for most applications. You specify a minimum and maximum value, and the generator produces numbers within that range.
Yes! You can generate any quantity of random numbers in a single batch. Simply specify how many numbers you need, set your range, and choose whether you want unique numbers only. This is perfect for creating test data, raffle picks, or classroom assignments.
When you enable 'unique numbers only', each generated number will be different from all others in the batch. This is essential for raffles, random selection without replacement, or any scenario where you can't have duplicates. Note that you can't generate more unique numbers than the range allows (e.g., you can't generate 20 unique numbers from a 1-10 range).
Yes, the generator includes sorting options. You can display numbers in ascending order, descending order, or keep them in random order. Sorting is helpful when you need to organize the results for easier reading or when the order matters for your use case.
For most practical purposes, yes. We use the Web Crypto API's getRandomValues() when available, which provides cryptographically strong random numbers. For applications requiring true randomness (like cryptographic keys or scientific simulations), specialized hardware random number generators may be more appropriate.
You can use any range within JavaScript's safe integer limits. For practical purposes, this means ranges from -9,007,199,254,740,991 to 9,007,199,254,740,991. Most common use cases like dice rolls (1-6), raffle numbers (1-1000), or test data generation work perfectly.
