About this tool

List Shuffler randomizes any list of items in your browser using an unbiased Fisher-Yates (Knuth) shuffle. Two modes are available. Crypto-strong mode draws each random pick from crypto.getRandomValues, the same source modern browsers expose for security work, so every press of Shuffle gives a fresh order that no one can predict in advance. Seeded mode uses a deterministic PRNG (xmur3 string hash feeding an sfc32 generator), which means the same seed plus the same list always produces the same order: anyone with the seed can reproduce a raffle, a draft pick, or a question order and verify the result. Items can be separated by new lines, commas, semicolons, spaces, or a custom separator, with optional trim, remove blank lines, and remove duplicates filters that apply before the shuffle. Up to 10 independent shuffles can be generated in one batch (useful for tournament rounds or multi-stage draws). Every shuffle has a copy button for the single result and an aggregate copy button for the whole batch. The shuffle, the seed, and the list never leave your browser.
