Troubleshooting

List parsing issues? If your items contain both commas and new lines, the tool prioritizes new lines for splitting. Ensure a consistent separator for the best result.
Duplicate results appearing? Make sure the 'Remove Duplicates' toggle is active if you suspect your source data has repeated entries.
Slow performance? For lists larger than 20,000 lines, close other browser tabs to free up memory for the randomization process.

Pro Tips for Creators

Use the 'Pick a Winner' mode for giveaways to avoid cluttering the screen with the rest of the non-winning entries.
If you're using this for a classroom or office team-up, shuffle the list first, then group every N items to create perfectly random teams.
Combine this with our 'Case Converter' if you need to clean up messy text data before performing a professional draw.

Frequently Asked Questions

Is the randomization truly unbiased?

Yes. We use the Fisher-Yates shuffle with 'Math.random()', which leverages browser-level entropy. This is the mathematical gold standard for generating random permutations.

How many items can I randomize at once?

The tool can handle thousands of lines. While performance depends on your device's RAM, most lists up to 10,000 items shuffle in under a second.

Is my list data private and secure?

100%. Unlike other online pickers, we do not store or transmit your list to any server. Your data only exists in your temporary browser session.

Can I pick more than one winner at a time?

Yes! You can toggle the 'Pick Winner' mode and set the desired number of results to extract multiple winners from a single pool.

How do I ensure a fair giveaway for my followers?

We recommend recording your screen while using the 'Randomize' button to provide transparent proof of the draw process to your audience.
