About the Random Number Generator

Picking a raffle winner, sampling records or rolling dice for a game all need numbers that nobody can predict or influence. This generator draws whole numbers between a minimum and maximum you set, using the browser's cryptographic random source, and can produce up to 1,000 at once, with or without repeats.

What you can do

• Set a minimum and maximum anywhere from -1,000,000 to 1,000,000.
• Generate between 1 and 1,000 numbers in one draw.
• Turn on Unique to get numbers with no repeats, drawn by shuffling the whole range.
• Copy the results as a list, one number per line.

When it works best

• Drawing winners for a giveaway from numbered entries.
• Choosing a random sample of row IDs to spot-check in a database.
• Rolling dice or picking lottery-style numbers for a board game or class activity.

Things to know

• Numbers are generated in your browser; no record of a draw is kept, so take a screenshot if you need proof.
• Only integers are produced, and both ends of the range can be drawn.
• Unique mode reports an error if you ask for more numbers than the range contains.
• For random identifiers, use the UUID Generator. For random passwords, use the Password Generator.
