How random is it?
This generator uses your browser's built-in random number functions, which are perfectly suitable for giveaways, lucky draws, classroom picks, games and raffles — anywhere the goal is unpredictability to humans.
For cryptographic uses such as passwords and encryption keys, use a dedicated password generator with a cryptographic random source instead — general browser randomness is not certified for that purpose.
Popular ways people use it
Giveaways and lucky draws: number your participants, generate the winning number live — fair and transparent.
Games and classrooms: dice alternative, bingo caller, random student picker, random team assignment.
Sampling and audits: pick which invoice numbers or rows to check from a numbered list.
Decisions: settle “you pick / no you pick” debates with a number between 1 and 2.
Frequently asked questions
Can the same number appear twice?
Yes — each number is drawn independently, like rolling a die repeatedly. For unique draws, generate one at a time and skip repeats, or rerun.
How do I pick a giveaway winner fairly?
Number the entries, set the range to match, and generate one number live on stream or in front of witnesses. Transparency beats trust.
Does this work like a lottery machine?
It approximates one for casual purposes. Lotteries use certified hardware draws; for office raffles this is plenty.
What is the biggest range I can use?
Anything from very large negatives to very large numbers — JavaScript handles integers up to 9,007,199,254,740,991 safely.
Is this random number generator free?
Yes — free, unlimited, and no data is sent anywhere.
