Raster vs Vector for Web — Which Format to Use

For logos and icons: SVG vector. For photos and complex images: WebP raster. For decorative illustrations: depends on complexity. Here's the decision framework.

When to Use SVG (Vector) on the Web

SVG is the right choice for specific types of web graphics.

  • Logos: SVG looks sharp at any screen resolution — retina, 4K, mobile
  • Icons and UI elements: SVG icons scale perfectly and support CSS theming
  • Simple illustrations: flat-design illustrations, charts, diagrams
  • Animations: CSS-animated SVG is smooth and lightweight
  • Interactive graphics: SVG supports JavaScript interaction natively

When to Use Raster (PNG/WebP/JPEG) on the Web

Raster formats are better for complex visual content.

  • Photography: WebP at 80% quality is 30–50% smaller than JPEG with same visual quality
  • Complex illustrations with many colors: WebP may be smaller than detailed SVG
  • Product images: WebP for e-commerce product photos
  • Screenshots and UI mockups: PNG or WebP (SVG conversion adds no value)
  • Social media images: WebP or JPEG — SVG not accepted by most social platforms

Frequently Asked Questions

Should my website logo be SVG or PNG?

SVG — always for logos. SVG logos look sharp on retina displays, scale to any size without a separate 2x file, and are typically 5–20KB vs 50–200KB for equivalent PNG. Use inline SVG or <img src='logo.svg'> with a PNG fallback for older browsers.

When should I convert a PNG to SVG for web use?

Convert to SVG when: it's a logo, icon, or simple illustration; it needs to scale across device sizes; you want CSS color control. Don't convert to SVG when: it's a photo; it has complex textures; the SVG would be larger than the optimized WebP.

Does SVG hurt Core Web Vitals?

Large inline SVG can increase HTML document size and delay LCP. Best practice: externalize SVG files larger than 10KB (<img src='logo.svg'>), optimize SVGs with SVGOMG, and use <link rel='preload'> for above-the-fold SVG images.

Is WebP better than SVG for a website background image?

For photographic or complex pattern backgrounds: WebP is better. For simple geometric or flat-color pattern backgrounds: SVG is better — an SVG pattern tile scales without loss and is often a few KB. The right format depends on the specific background design.
