Can I randomize a list with duplicate items?

Yes, all three tools process duplicate entries as separate items unless a 'remove duplicates' option is explicitly provided. 10015.io and PineTools will keep duplicates in the shuffled output, while RANDOM.ORG's behavior depends on the specific list configuration.

Do these tools store my list data after I submit it?

10015.io processes lists entirely in the browser, so nothing is sent to their servers. PineTools and RANDOM.ORG also operate client-side for typical list randomization, but RANDOM.ORG's broader site includes other services that may handle data differently, so check their privacy policy for sensitive inputs.

What is the maximum list size these tools can handle?

The material does not specify upper limits for list length. All three tools accept multi-line text input, but very large lists may cause performance slowdowns depending on your browser and device.

Can I get a specific number of random items from my list, rather than shuffling the whole thing?

10015.io includes a 'Number of Selection' field that lets you choose how many items to draw randomly. PineTools and RANDOM.ORG primarily shuffle the entire list, though RANDOM.ORG's broader platform offers additional drawing and sampling utilities beyond the basic list randomizer.

Is the randomization truly random, or just pseudo-random?

10015.io and PineTools use standard pseudo-random algorithms built into web browsers. RANDOM.ORG explicitly uses certified physical randomness derived from atmospheric noise, making it the only tool in this group with verifiable true randomness for critical selections.

Buyer's guide

How to choose a list randomizer

When you need to randomize a short list of names or items quickly and want results stay on your device, choose a browser-only tool like 10015.io. If you value a polished interface with clear copy and download buttons and don't mind a simpler feature set, PineTools offers a more refined experience. For situations where genuine cryptographic randomness matters — such as raffles, scientific sampling, or anything requiring verifiable unpredictability — RANDOM.ORG is the only option that uses certified physical randomness rather than a pseudo-random algorithm.
