PNG vs SVG for QR Codes
Choose between PNG and SVG QR code downloads. Covers scaling, print workflows, editing, file size, and compatibility.
When to use PNG
PNG is a raster image with a fixed pixel size. It is easy to preview, upload, and use in documents, slides, and social posts. Choose PNG when the final display size is known and you want predictable rendering.
For print, choose a PNG size that matches the final dimensions at the printer's resolution. A 512 px PNG is not enough for a large poster, while a 2048 px PNG may be unnecessarily large for a small label.
When to use SVG
SVG is a vector format. It scales without losing sharpness and is usually smaller for simple black-and-white QR codes. Choose SVG for logos, packaging, signage, and any design that may be resized later.
SVG files can be edited in design tools, but avoid changing module shapes or removing the quiet zone. The QR pattern must remain intact.
Practical recommendation
Use PNG for screens and everyday documents. Use SVG for print, signage, and design workflows. When in doubt, download both and test the exact final size.

This guide is based on QRKit's practical testing, public platform documentation, and common failure modes reported by users. Recommendations are conservative and should be tested on the exact devices, materials and print conditions you plan to use.
