When generating a QR code for a flyer, business card, or billboard, the file format you choose matters tremendously.
Raster (PNG/JPG) vs. Vector (SVG)
Raster images (PNG/JPG) are made of a fixed grid of pixels. If you generate a 200x200 pixel QR code and try to stretch it onto a large poster, the pixels stretch, resulting in a blurry, pixelated image. Blurry QR codes are notoriously difficult for smartphone cameras to read.
Vector images (SVG) use mathematical equations to define lines and shapes. An SVG QR code is essentially a set of instructions: "Draw a black square here, draw a white square there."
The Benefits of SVG
- Infinite Scalability: You can scale an SVG QR code to the size of a skyscraper or shrink it down to a postage stamp, and it will remain razor-sharp.
- Smaller File Size: Because it uses math instead of storing individual pixel data, SVG files are often smaller in byte size.
- Easy Recoloring: Vector graphics can be easily manipulated in design software like Adobe Illustrator or Figma without losing quality.
