AVIF

AVIF Strengths

  • Best-in-class compression — typically 20–50% smaller than WebP at equivalent quality
  • Native HDR and wide color gamut (BT.2020) support
  • Supports 8, 10, and 12-bit color depth
Limitations
  • Encoding is highly CPU-intensive — significantly slower than JPEG or WebP
  • Requires Edge 121+ (not supported in earlier Edge versions)
  • Limited support in native desktop image viewers
DXF

DXF Strengths

  • Universally supported by almost every CAD program, 3D modeler, and vector graphics editor in existence
  • ASCII structure is human-readable and can be parsed or generated programmatically with relative ease
  • The de facto standard for sending 2D cutting paths to CNC routers, plasma cutters, and laser engravers
Limitations
  • ASCII DXF files can be enormously large and inefficient compared to binary DWG files
  • The format relies heavily on legacy AutoCAD data structures, making complex 3D entity parsing extremely difficult for third-party developers
  • Lacks native web browser rendering capabilities
