Is the QR code generated on a server?

No — it’s drawn entirely in your browser, so whatever you encode (links, Wi-Fi passwords, contact details) never leaves your device.

Do these QR codes expire?

Never. The code is the data — there’s no account, no shortener and no service in the middle that could shut down or start charging.

PNG for chats, documents and slides. SVG for print and design work — it scales to any size, from a business card to a billboard, without blurring.

It adds redundancy so the code still scans when partially covered or damaged. Use High if the code will be printed small or might get scuffed.

Type anything, get a scannable code instantly — download it as PNG or print-ready SVG.
