SVG vs PNG: When to Use Each Format

Published on March 1, 2026

SVG is best for logos, icons, and graphics that need to scale to any size without losing sharpness. PNG is best for photos, screenshots, and images with complex colors. The key difference: SVG uses math (vectors) to draw shapes, while PNG stores individual pixels.

Key Differences at a Glance

  • Scalability: SVG scales infinitely without blur. PNG gets pixelated when enlarged beyond its original resolution.
  • File size: A simple SVG icon might be 2KB. The same icon as a high-res PNG could be 50KB+. But a complex SVG with thousands of paths can exceed a PNG equivalent.
  • Transparency: Both support transparency. PNG uses an alpha channel. SVG supports transparency natively.
  • Editability: SVG files are XML text - you can edit colors, shapes, and sizes with code or a vector editor. PNG edits require image editing software.
  • Browser support: All modern browsers render both formats. SVG support has been universal since 2015.

When to Use SVG

Use SVG for logos, icons, illustrations, charts, and any graphic that appears at different sizes across your site. SVGs look crisp on retina displays without needing 2x or 3x image versions. They also load faster for simple graphics because the file sizes are tiny. Most design tools (Figma, Illustrator, Inkscape) export SVG natively.

When to Use PNG

Use PNG for photographs, screenshots, and images with complex color gradients where you need lossless quality. PNG handles millions of colors and preserves every pixel exactly as captured. If you need smaller file sizes for photos, consider converting PNG to JPG for lossy compression, or converting to WebP for better compression with similar quality.

What About Web Performance?

For web use, the ideal setup is SVG for UI elements and WebP or AVIF for photos. PNG works as a fallback where WebP is not supported. If your site has heavy PNG images, try compressing them or switching to a more efficient format. Our WebP vs PNG comparison covers this in detail.
