QR code as PNG or SVG: which should you download?
A QR code contains the text or URL you encode. PNG and SVG can represent the same data, but they behave differently when you resize or print the artwork.
PNG for ordinary documents
PNG is a pixel image that works well in presentations, messages, and websites. If it is enlarged far beyond its original size, edges may become fuzzy.
SVG for sharp printing
SVG describes the QR modules as scalable shapes, so the code stays sharp for flyers, posters, and other print sizes. Check whether your printer or design tool supports SVG before relying on it.
Keep the quiet zone clear
Leave a clear margin around the QR code. Avoid cropping the modules, placing text across the pattern, or using colors with weak contrast.
Test the actual destination
Scan the exported code with a phone before printing or distributing it. If it links to a website, verify the URL and destination. A QR code does not make a link safe; never include passwords or private credentials in a public code.
