How to use List Randomizer

Paste a list into the box, one item per line, and this tool shuffles it into a genuinely random order using a Fisher-Yates shuffle driven by the Web Crypto API's cryptographically secure random number generator — not a biased sort-based shuffle. Optionally remove duplicate or empty lines first, or switch to "pick N" mode to draw only a handful of random items, such as picking winners from a list of entries. Copy the result or download it as a .txt file when you're done. Nothing you paste is ever uploaded — the shuffle runs entirely in your browser.

Frequently asked questions

Is this shuffle truly random and fair?
Yes. It uses a proper Fisher-Yates shuffle driven by crypto.getRandomValues(), the Web Crypto API's cryptographically secure random number generator — not Math.random() and not the common but biased array.sort(() => Math.random() - 0.5) trick, which produces a non-uniform, skewed order. Every possible ordering of your list is equally likely.
Can I pick just a few random winners from a list instead of shuffling the whole thing?
Yes. Turn on "Pick N random items" and enter how many you want — the tool shuffles the full list first and then takes the first N, so picking 3 winners from a list of raffle or giveaway entries is fully fair and unbiased.
Can I remove duplicates before shuffling?
Yes. Check "Remove duplicate lines before shuffling" to drop repeated entries before the shuffle runs, so no item can be picked or appear more than once.
Does this upload my list anywhere?
No. Your list is never sent to a server — the entire shuffle happens locally in your browser's JavaScript engine, and nothing you paste is stored or transmitted.
