A QR code that looks crisp on screen can turn into an unscannable blur on a billboard, or a fuzzy smudge on a business card, if you export it in the wrong format. Choosing between SVG and PNG is the difference between a code that scans flawlessly at any size and one that fails in print.
Understanding Raster vs Vector Graphics
A PNG is a raster image made of a fixed grid of pixels, so enlarging it past its native size makes the edges soft and blocky. An SVG is a vector image defined by math, so it stays perfectly sharp at any size, from a stamp to a stadium banner. That single difference drives every format decision below.
When to Use PNG (Digital Marketing, Emails, Web)
For screens, PNG is ideal: it's universally supported and renders instantly in emails, social posts, and web pages where the display size is fixed and modest. Export a standard PNG QR at the size you'll actually display it and it'll look clean.
When to Use SVG (Billboards, Print Merch, Professional Design)
For anything printed large or that a designer will resize, SVG is the right call. Billboards, posters, packaging, and merchandise all benefit from a vector code that scales without losing sharpness. A custom vector SVG code can be dropped into professional design tools and enlarged freely.
How Our Rendering Engine Ensures Flawless Scaling
A good generator produces clean geometry with crisp module edges and proper quiet zones, so the code scans reliably whether it's an inch wide or ten feet wide. Starting from a high-quality export is the simplest way to avoid scanning failures in the field.
