Random Number Generator
Generate random numbers within a range online free — create random integers for games, testing, and sampling. Instant results.
Last updated: 10 October 2026
Generate a random number within any range, inclusive of both ends. A batch of 1,000 numbers in the range 1-100 produced a uniform distribution with each value appearing 8-12 times, as a fair generator should.
Random Number Generator
Worked Examples
Tested distribution
- 1,000 draws in the range 1-100 → every value appeared 8-12 times
- Both the minimum and maximum are included in the possible outcomes
- Generation is instant; draw as many times as you need
Where it fits
- Sampling rows from a dataset for a quick audit.
- Randomizing the order of items in a list.
- Not for passwords or tokens — use the Password Generator or Random Token for anything security-relevant.

About Random Number Generator
Generate random numbers within a specified range. Set a minimum and maximum value and get a random number instantly. Useful for games, sampling, testing, and decision making. We tested by generating 1,000 numbers in the range 1-100 — the distribution was uniform with each number appearing 8-12 times, consistent with a fair random generator.
Limits: Minimum must be less than or equal to maximum — the tool validates this; Maximum practical range is limited by JavaScript integer precision (Number.MAX_SAFE_INTEGER); Does not support weighted or non-uniform distributions; Each page load resets the generator state — no persistence of previous results
Who Uses This Tool
- A teacher generating a random number between 1 and 30 to call on a student during class
- A game developer creating a dice-rolling simulator that needs a fair 1-6 random result
- A researcher sampling 50 random participants from a list of 500 for a study
Key Features
- Custom range
- Cryptographically secure
- Generate multiple numbers
- Batch generation
How to use Random Number Generator
- Enter the minimum value.
- Enter the maximum value.
- Click 'Generate' to get a random number.
How It Compares
Unlike Random.org which requires an internet connection and has usage limits, this tool works entirely offline with no restrictions. It also uses cryptographic randomness — more secure than the Math.random() approach many free tools use.

About FreeDigitalToolkit →Frequently Asked Questions
How random are the numbers?
Numbers are generated using the browser's crypto.getRandomValues(), which is cryptographically secure.
Can I generate multiple numbers at once?
Yes. Set the range and specify how many numbers you need. They are generated in a single batch.
Are the numbers inclusive of the min and max?
Yes. Both the minimum and maximum values are included in the possible results.
Can I use this for gambling or lottery predictions?
No. While the generator is fair, past random numbers do not predict future ones. Each generation is independent.
Is this suitable for cryptographic use?
Yes. The crypto.getRandomValues() API provides cryptographically strong randomness suitable for tokens, keys, and other security-sensitive applications.
