Why rebuild instead of upscaling?
Enlarging a small raster image makes it bigger, not sharper: edges get soft and printers turn the blur into grey fringes that confuse scanners. Because a QR code is a grid of modules, we can do better. The converter decodes the content and draws a brand-new code with perfectly square edges, in vector formats that stay crisp at billboard size.
Things to know
- The rebuilt code carries identical content but may not look pixel-identical: the original generator might have used a different mask pattern or error-correction level. Both scan to the same result.
- You can restyle it at the same time: colours, patterns, a logo, and SVG, PDF, EPS or PNG output.
- If the original points to a dynamic QR service, the new code points to that same service. Check that it's still active before you reprint.
