Random Number Generator
About this tool
From raffle draws and classroom pickers to sampling test data and deciding who goes first, a decent random number generator is one of those tools you reach for more often than you expect. Set your minimum and maximum, choose how many numbers you want, and decide whether duplicates are allowed — then hit generate. Numbers are drawn with your browser’s cryptographic random number generator (the same source behind secure tokens), not the weaker Math.random(), so the output is suitable for anything short of actual cryptography.
Two options deserve a note. Disabling duplicates turns the tool into a sampler: ask for 6 numbers between 1 and 49 and you have a lottery ticket picker; the tool will warn you if you ask for more unique numbers than the range contains. Sorting the output ascending is handy for bingo-style draws and for pasting into spreadsheets. Results can be copied with one click, comma-separated, ready to drop into a document or a group chat. Nothing is sent anywhere — every draw happens on your device.
