JPEG Strengths

  • Universal support — every browser, OS, and application handles JPEG
  • Excellent compression for complex photographs with natural color gradients
  • Rich metadata support: EXIF (GPS, camera settings), ICC color profiles
Limitations
  • No transparency — cannot have a transparent background
  • Lossy compression introduces visible artifacts on sharp edges and text
  • No animation support
SVG

SVG Strengths

  • Provides infinite resolution scalability, looking perfectly crisp on high-DPI (Retina) displays without increasing file size
  • Extremely lightweight compared to raster formats for flat graphics, logos, and UI elements
  • Can be manipulated dynamically via the browser's CSS and JavaScript engines (DOM integration)
Limitations
  • Unsuitable for complex photographic images or photorealistic textures
  • Poses critical security vulnerabilities (XSS and XML External Entity attacks) if user-uploaded SVGs are not heavily sanitized
  • Rendering performance degrades significantly if the SVG contains tens of thousands of complex nodes or deeply nested paths
