A seed makes the draw repeatable: the same seed, range and settings give the same numbers every time, on any device. Leave it empty and the browser's cryptographic source is used instead, which nobody can reproduce.
Every draw is truly random and cannot be predicted or repeated. Nothing you enter is recorded.
How to Use the Random Number Generator Online
Set a lowest and a highest value and press for one number between them, with both ends included. Whole numbers by default, or up to six decimal places if you need them. You can list values that must never come up, and add a seed when a draw has to be repeatable for a demonstration or an audit.
Draws a number between two values with every value equally likely, including both endpoints. Whether the range is inclusive matters more than it sounds: an off-by-one at the boundary is the classic bug in a prize draw, and it is the sort that is only noticed by whoever lost.

-
It draws numbers, not names. Paste a list into Random Winner Picker for that.
Frequently Asked Questions
Answers to common questions about this tool.
Do I need to install anything to use the Random Number Generator?
No. Random Number Generator runs entirely in your browser — there is nothing to download, no extension and no desktop program. It works the same on Windows, macOS, Linux, Android and iPhone.
Is it safe to use the Random Number Generator online?
Safer than the usual alternative, yes. Most online tools upload your file to a server you know nothing about, where it sits until someone deletes it. Here the file never leaves your device — the processing happens in the page itself, so there is no server copy to leak, retain or sell.
Is my text sent anywhere when I use Random Number Generator?
No. The text you paste is handled in your browser and never leaves the page. That makes it safe for drafts, customer lists and anything else you would rather keep to yourself.
Is there a limit on how much text I can paste?
The site sets none. Long documents are handled by your own device, so a whole book may be slow on an older phone. Articles, essays and long lists are no trouble.
Can I use Random Number Generator without making an account?
Yes. There is no login, no email to hand over and no daily limit. Open the page, paste or type, and copy or download the result when it is ready.
Why does my word count differ from Microsoft Word?
Programs treat hyphenated words, numbers and symbols a little differently. The gap is usually a few words in a long piece. If a teacher or portal sets a limit, stay a little under it to be safe.
Do the QR codes made here expire?
No. The information is stored directly in the pattern, with no redirect through our servers, so the code keeps working for as long as the link or text inside it stays valid.
