SVG vs PNG: Complete Guide
Understanding when to use vector graphics (SVG) versus raster graphics (PNG) is essential for web design and development.
SVG (Vector)
Made of mathematical paths and shapes. Scales infinitely without losing quality.
PNG (Raster)
Made of pixels in a grid. Fixed resolution - becomes pixelated when scaled up.
→Use SVG For:
- Logos and brand marks
- Icons and icon systems
- Simple illustrations
- Charts and graphs
- Animated graphics
- Responsive graphics
→Use PNG For:
- Photos with transparency
- Complex illustrations
- Screenshots
- Detailed artwork
- When vector source isn't available
- Textures and patterns
| Feature | SVG | PNG |
|---|---|---|
| Scalability | Infinite (Vector) | Fixed resolution |
| File Size (Icons) | Usually smaller | Larger |
| Transparency | ||
| Animation | CSS/JS animation | APNG only |
| Editable in Code | Yes (XML) | No |
| Retina Ready | Automatically | Need 2x/3x versions |
| Photo Support | Poor | Excellent |
| Browser Support | 100% | 100% |
🏢 Company Logo
Best: SVG — Scales perfectly on business cards (tiny) to billboards (huge). One file for all sizes.
🎨 App Icons
Best: SVG → export to PNG — Design in vector, export to required PNG sizes (16px, 32px, 192px, 512px).
📸 Product Photo with Transparent Background
Best: PNG — Photos are raster by nature. Use WebP if browser support allows.
📊 Interactive Chart
Best: SVG — Can animate data, add hover effects, and style with CSS.
💡 Performance Tip
For icons, always use inline SVG when possible. It eliminates an HTTP request, allows CSS styling, and enables animation. Icon libraries like Lucide, Heroicons, and Feather provide optimized SVG icons.
