SVG vs PNG vs PDF: QR Code Export Formats

Choosing the right file format for your QR code affects print quality, file size, and editing flexibility. Each format serves different use cases.

SVG (Scalable Vector Graphics)

Best for: Print design, large-format output, any scenario requiring scaling.

SVG files describe the QR code as mathematical shapes (rectangles), making them resolution-independent. They scale from a postage stamp to a billboard without quality loss.

Advantages: - Infinite scalability with perfect sharpness - Small file size (typically 5-50 KB) - Editable in vector tools (Illustrator, Figma, Inkscape) - Perfect for custom colours and design modifications

Disadvantages: - Not directly embeddable in all applications - May render differently across software

PNG (Portable Network Graphics)

Best for: Web display, email, social media, and applications requiring raster images.

PNG files are pixel-based with lossless compression. They preserve sharp module edges without JPEG artefacts.

Advantages: - Universal compatibility across all platforms - Lossless compression preserves module sharpness - Transparency support for non-white backgrounds - Direct use in web pages, emails, and documents

Disadvantages: - Fixed resolution — quality degrades when enlarged - Larger file size at high resolution

Resolution guidance: - Web display: 200-400 pixels wide - Print: 300 DPI at the target physical size (e.g., 3 cm = 354 px) - Large format: Generate from SVG at the target resolution

PDF (Portable Document Format)

Best for: Professional print workflows, document embedding.

PDF can contain either vector or raster QR code data. Vector-based PDFs behave like SVGs with universal print compatibility.

Advantages: - Standard format for print production - Can embed vector data for scalability - CMYK colour space support for professional printing

EPS (Encapsulated PostScript)

Best for: Legacy print workflows, professional prepress.

EPS is an older vector format still used in some print production pipelines. Modern workflows typically prefer SVG or PDF.

Format Selection Guide

Use Case	Recommended Format
Website or app	PNG (or inline SVG)
Business card printing	SVG or PDF
Large format (poster, banner)	SVG
Email attachment	PNG
Professional prepress	PDF or EPS

Key Takeaways

SVG for print and scaling — vector, resolution-independent
PNG for web and digital — universal, lossless, fixed resolution
PDF for professional print — combines vector quality with print standards
Never use JPEG for QR codes — compression artefacts destroy module edges
Generate at the highest quality needed and convert down as required
