Random Number Generator
Generate up to 500 random integers per run, enforce unique draws, sort the results, and copy an audit-ready summary with this private random number generator.
What is the Random Number Generator?
The Random Number Generator is a browser-based range picker for marketing ops teams, QA leads, teachers, and analysts who must show that a draw was fair. It normalizes inputs, enforces uniqueness when needed, and produces shareable summaries that explain the range, quantity, and ordering of every run.
How Random Number Generator Works
Random Number Generator runs directly in your browser and applies deterministic logic to transform the input into the final output. The tool validates your input, processes it instantly, and returns consistent results based on the selected options. This keeps generate up to 500 random integers per run, enforce unique draws, sort the results, and copy an audit-ready summary with this private random number generator. fast, private, and repeatable without sending data to a server.

How to Use the Random Number Generator
Enter the smallest whole number you want to allow in the Minimum field.
Enter the largest whole number you need in Maximum; the range is inclusive.
Set Quantity (1-500), decide if Unique values only should be enabled, and choose the Order that best matches your documentation needs.
Run the tool and review the status, generated list, and summary card before sharing or exporting the numbers.

FAQ
Is this randomness strong enough for giveaways?
The tool relies on the browser's cryptographic random source when available and falls back to Math.random otherwise. It is ideal for marketing giveaways, seating charts, and sampling. For regulated gambling or compliance-grade drawings, use a certified hardware RNG and keep this tool for planning.
Can I generate decimal or floating-point numbers?
No. The generator only outputs whole numbers so results can be referenced easily. If you need decimal values, generate integers and divide them manually afterward.
How many numbers can I generate at once?
You can request between 1 and 500 numbers per run. This limit keeps the interface fast and prevents browsers from freezing.
Are any of the numbers stored or sent to a server?
Nothing leaves your browser. Inputs, results, and summaries stay local, so contest IDs or internal task numbers remain private.
Can I reproduce the exact same sequence later?
The generator does not expose seeding or history, so it cannot recreate a past list automatically. Capture the status summary or export the numbers if you need an audit trail.
What does the Order setting change?
Order only affects how the generated numbers are displayed. The draw always occurs randomly; sorting just reorganizes the list for easier reading.
