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
EDMICS-RLC

EDMICS-RLC Strengths

  • Simple, computationally inexpensive Run-Length Coding enabled rapid compression and decompression on low-power legacy hardware
  • Deeply integrated into Fuji Xerox enterprise hardware for seamless, automated scan-to-archive workflows
Limitations
  • Completely proprietary and closed-source, making modern archival extraction and migration extremely difficult
  • No support in modern image processing libraries like ImageMagick, libvips, or standard viewers without bespoke decoding tools
  • RLC compression is far less efficient than modern algorithms like PNG (Deflate) for complex documents
