Why SVG QR Codes Are Better Than PNG

The Format Dilemma

When downloading a QR code, you're typically offered two formats: PNG (raster) or SVG (vector). While both work, SVG offers significant advantages for most use cases.

What's the Difference?

PNG (Portable Network Graphics)

PNG is a raster format that stores images as a grid of pixels. When you zoom in or scale up, the image becomes pixelated and blurry.

SVG (Scalable Vector Graphics)

SVG stores images as mathematical paths and shapes. This means they can be scaled to any size without losing quality.

Why SVG Wins for QR Codes

1. Infinite Scalability

Need your QR code on a business card AND a billboard? With SVG, you use the same file for both. The QR code remains crisp and scannable at any size.

2. Smaller File Sizes

For simple graphics like QR codes, SVG files are typically much smaller than high-resolution PNGs. This means faster loading times on websites.

3. Easy Customization

SVG files are essentially XML text. You can:

• Change colors with CSS
• Add animations
• Modify shapes programmatically
• Integrate seamlessly with web applications

4. Better Print Quality

Print shops prefer vector formats because they produce the sharpest possible output. No more worrying about DPI or resolution.

5. Accessibility

SVG supports metadata and can be made more accessible to screen readers and other assistive technologies.

When to Use PNG

PNG still has its place:

• Social Media - Some platforms don't support SVG uploads
• Email - Better email client compatibility
• Quick Sharing - Universal support across all devices

Best Practices

1. Generate at SVG first - You can always convert to PNG later
2. Use high error correction - Ensures scannability at any size
3. Test at target sizes - Verify the code scans correctly
4. Keep backups - Store your original SVG files

The Bottom Line

For professional use, especially print materials and websites, SVG is the superior choice. Snapkit creates high-quality QR codes that you can download in your preferred format.
