Are these numbers truly random?

Yes, for everyday use. The generator uses your browser's cryptographically secure random source (Web Crypto API, crypto.getRandomValues), which provides excellent statistical distribution and unbiased results suitable for raffles, giveaways, statistical sampling, QA test data and games. It is the same standard used by serious password managers.

What is the maximum range I can use?

You can use any safe integer range. The tool supports values up to JavaScript's safe-integer ceiling (2^53 − 1, or about 9 quadrillion), which is more than enough for any practical need from raffles to scientific sampling. Just make sure the minimum is always lower than the maximum.

What does no duplicates mean?

When the No duplicates option is checked, every number in the generated batch is unique. Example: generating 10 numbers from 1 to 10 with no duplicates returns every number from 1 to 10 in random order, with no repeats. This is exactly what you want for raffle draws and random sampling without replacement.

Can I generate decimals or floating-point numbers?

This tool is optimized for whole numbers (integers). For decimal output, generate an integer in a wider range (e.g. 0 to 1,000,000) and divide manually (e.g. by 1,000,000 to get 0.000000-1.000000), or let us know via the Contact page and we will add a decimal mode.

Is this suitable for cryptography or security keys?

For games, raffles, sampling and general-purpose randomness, the tool is perfect. For production cryptographic key generation, security tokens or sensitive protocols, you should use a dedicated server-side cryptography library (Node crypto, OpenSSL, libsodium) inside a controlled environment.

Why are my generated numbers not what I expected?

True randomness sometimes produces clusters or runs (like getting 7, 8, 9 in a row), which feel non-random but are actually a sign that the generator is unbiased. If you want every number to be unique, enable No duplicates. Also double-check that your minimum is lower than your maximum and that the range is wide enough for the quantity you requested.

What can I use random numbers for?

Plenty of use cases: giveaways and raffles (assign a number per entrant), tabletop and D&D-style games (digital dice), classrooms (randomly call on students or generate practice problems), QA and software testing (random data sets and edge cases), tie-breaking decisions (where to eat, who goes first) and statistical sampling for research and surveys.

Minimum

Maximum

How many

No duplicates

Set your range: enter the Minimum (starting) and Maximum (ending) numbers that define the pool you want to draw from.
Quantity: in the How many field, type how many random numbers you need to generate at once (one for a quick coin-flip, many for a sample or raffle).
Unique results: tick the No duplicates checkbox if you want every generated number to be different, which is the right setting for raffles and survey samples.
Generate: click Generate to see the results appear instantly in the result box, regenerate as many times as you like.
Copy: hit the Copy button to send the full batch to your clipboard for use in Excel, Google Sheets, scripts, presentations or chat.
