DNG

DNG Strengths

  • Openly documented specification guarantees long-term archival accessibility, freeing photographers from proprietary manufacturer lock-in
  • Lossless compression algorithms often result in files 15-20% smaller than uncompressed proprietary raw formats
  • Natively supported by modern smartphone operating systems (iOS and Android) for high-end mobile photography
Limitations
  • Conversion from proprietary raw to DNG takes processing time and can strip specific, proprietary manufacturer metadata (like active D-Lighting or in-camera lens corrections)
  • File sizes are massive compared to standard JPEGs or HEIC files
  • Cannot be rendered natively in web browsers without server-side processing or WebAssembly decoders
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

When to choose which format

DNG
Use DNG when…
  • Digital Photography Archival
  • Mobile Raw Capture (iOS ProRAW / Android Camera2 API)
  • Cross-Platform Raw Editing Workflows
SVG
Use SVG when…
  • Web Logos & UI Icons
  • Responsive Web Design Elements
  • Interactive Data Visualizations (D3.js)
  • CSS and SMIL Web Animations
