FAQ
Can I use this for event tickets?
Yes, but the codes are unauthenticated static values, not signed tickets.
How are files named?
Sequentially, qr-001.png and so on, in input order.
Is there a limit on the number of codes?
Only browser memory and patience; a few hundred is comfortable.
Files never leave your device
Processing happens in your browser using the File API, WebAssembly and Web Workers. There is no upload endpoint.
