Random Number Generator

What it does

The Random Number Generator produces one or many random integers or decimal numbers between a minimum and maximum you choose. Use a seed to reproduce the exact same numbers later, or leave the seed blank for a fresh draw every time.

Common use cases

• Generating test data for QA scripts and demos.
• Lottery-style picks and raffles.
• Sampling for simulations, statistics, or games.
• Teaching probability and basic statistics in a classroom.

Settings

• Type — integer or float. Floats respect the chosen decimal places.
• Minimum / Maximum — the inclusive range numbers are drawn from.
• How many — how many numbers to generate in one go.
• Unique values — when checked, no number repeats in the output.
• Sort — leave unsorted, or sort ascending/descending.
• Seed — type one, generate a random one, or leave it blank. The same seed and settings always produce the same numbers.

Privacy note

Everything runs in your browser. Numbers are never uploaded, logged, or sent to a server — this page works the same with your network disconnected.

FAQ

Are these numbers cryptographically secure? No — this generator uses seeded, reproducible randomness, which is the point: it lets you regenerate the same numbers later. For passwords, PINs, or other secrets, use a generator in the Security section instead, which always uses your browser’s cryptographic random number source and has no seed.

Can I generate the same numbers again later? Yes — reuse the same seed and the same settings (range, count, type, sort) and you’ll get an identical result every time.

Is there a limit on how many numbers I can generate at once? Yes, to keep the page responsive. Very large counts show a warning before you generate, and the on-page preview shows only the first rows — the full output is still available via download.

Examples

• Minimum 1, maximum 100, count 10 → ten random integers between 1 and 100.
• Minimum 0, maximum 1, decimals 4, mode float → ten random decimals like 0.4821.
