Set how many you want, put any character in the text box (the page will not run on an empty one), and press Generate. They come back one per line, ready to copy or to save as a text file. Each is a version 4 UUID from crypto.randomUUID, the browser cryptographic random source, rather than from Math.random.
This page loads no libraries at all. The work is done by the browser itself. Your file is read on your own machine and never sent anywhere. Open your browser’s network tab and watch while you use it.
They come from crypto.randomUUID, the browser cryptographic random source, rather than from Math.random. A version 4 UUID holds 122 random bits; the other six say which version and variant it is, and those are fixed.
Up to a thousand. Ask for more and you get a thousand; leave the field empty, or put 0 in it, and you get five; a negative number gives one. They arrive as a single list, one UUID per line.
No. Version 4 only, which is random and carries no timestamp. If you want keys that sort by the time they were created, a v4 UUID does not do that, and there is nothing here that produces another version.
Nothing on this page: what you type there is ignored, and the count comes from the How many field. It does have to hold one character that is not a space, though. On an empty box the page answers "Paste something in first" instead of generating.
