Why Rasterization Size Matters

  • Platform asset requirements specify exact pixel dimensions — not percentages
  • Rasterizing too small loses sub-pixel detail that SVG math preserves
  • Rasterizing at 2× generates true retina assets for HiDPI screens
  • Favicon sizes (16px) need special attention to hinting and pixel snapping

SVG Rasterization Best Practices

  • Always keep the SVG master for future re-exports at any new size
  • Export at largest size first; downscale PNG for smaller sizes rather than re-rasterizing
  • For very small sizes (16px favicon), convert text to paths in the SVG first
  • Use 2× dimensions for any PNG destined for Retina or HiDPI screens
  • Verify SVG filter and font rendering in the output at small sizes
