PNG is a pixel image
PNG stores the QR as a grid of pixels. It is widely supported by office software, websites, email tools, presentations, and design applications.
A PNG looks sharp at its intended size, but enlarging a small file can soften edges or reveal pixelation.
SVG is vector geometry
SVG describes the QR modules as shapes. It can be enlarged from a business card to a sign without running out of pixels.
This makes SVG a useful production master for professional design, packaging, signage, and layouts whose final dimensions may change.
Choose PNG for common fixed-size uses
PNG is a practical choice for a presentation, document, email, web graphic, or ordinary small print placement when you export enough resolution.
Keep the aspect ratio square and avoid repeatedly resaving through tools that blur or compress the image.
- Easy software compatibility
- Useful for digital graphics
- Simple transparent-background support
- Requires enough pixels for final size
Choose SVG for print and flexible sizing
Use SVG when handing artwork to a designer or printer, placing a code on packaging, or producing posters and signs.
The file can still be damaged by editing. Cropping the quiet zone, stretching the art, changing module geometry, or placing it on a low-contrast background remains risky.
- Scales cleanly
- Editable in vector software
- Strong print handoff format
- Must preserve QR geometry
Keep both when possible
A useful workflow is to archive an SVG master and export PNG copies for routine digital use. Name both files after the destination or campaign.
Regardless of format, test the finished layout rather than assuming a technically valid source guarantees a scannable final product.
