Random QR Code Generator

This generates many QR codes at once, each holding a different random value. It exists for the jobs where you need a pile of codes that are guaranteed not to collide — raffle tickets, inventory labels, event passes, one-per-customer vouchers.

Values come from your browser's cryptographic random source, the same one used for generating keys. They are not predictable, and because nothing is generated on a server, nobody has a list of them but you.

What each option produces

Making them point at your own site

Put a URL in the prefix box and every code becomes a unique link — https://example.com/t/ plus the random value. Scanning takes the person to your page with the code in the address, so your site can look up what that ticket or voucher is.

That is how most ticketing and loyalty systems work underneath, and it keeps the codes static: your server decides what each one means, so you can change the behaviour later without reprinting anything.

Printing a batch

The download gives you a single SVG sheet with every code laid out in a grid and its value printed underneath. Being vector, it prints sharply at any size — send it straight to a printer or drop it into a label template.

For sticky labels, measure one cell of your label sheet and scale the SVG to match. Keep at least a few millimetres of white space around each code so the quiet zone survives the cutting.
