Do these QR codes ever expire?

No. These are standard static QR codes where the information is encoded directly into the pixel matrix. They work indefinitely and will never expire, require subscription renewals, or redirect through third-party servers.

Why is SVG format recommended for printing?

SVG (Scalable Vector Graphics) is resolution-independent. You can scale an SVG QR code to any size—from a business card to a highway billboard—without any pixelation or loss of sharpness.

How does the WiFi QR code work on smartphones?

When an iOS or Android smartphone camera scans the WiFi QR code, it recognizes the standardized WIFI:S: protocol and prompts the user with a 'Join Network' notification, connecting automatically without typing the password.

Which Error Correction Level should I use?

Level M (15%) is ideal for digital screens and general flyers. If you plan to print the code on rough textures, curved bottles, or outdoor banners exposed to weather, use Level H (30%) so the code remains scannable even if partially damaged.

Why Designers Use Vector SVG for QR Code Printing

Standard image files (like JPG and low-resolution PNG) are rasterized grids of pixels. If you stretch a 300x300 PNG onto a restaurant banner or poster, the edges blur and your customers' phone cameras struggle to scan it.

Vector SVG files are defined by geometric XML code. They scale from a tiny 1-inch business card sticker to a 20-foot outdoor billboard with zero loss of crispness. KitWharf exports pure SVG vector files with no watermarks or accounts required.
