How long do these QR codes last?

They last forever. The generated QR codes are standard static matrix symbols. They embed the content directly, meaning they do not expire and do not require any redirect servers or hosting to scan.

Why use SVG format?

SVG is a vector graphic format. Unlike PNG which gets blurry when resized, SVG can be scaled up to billboard size without losing any crispness. It is perfect for graphic designers, printing shops, and marketing flyers.
