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
canon-cr3
canon-cr3 Strengths
- Maintains 14-bit uncompressed sensor data, offering massive flexibility for recovering shadows and highlights in post-production
- The new C-RAW format offers roughly 40% smaller file sizes than uncompressed raw with virtually indistinguishable quality loss
- Utilizes the modern and extensible ISOBMFF container, moving away from archaic TIFF limitations
Limitations
- Being a proprietary format, it requires frequent software updates to third-party editing tools (like Lightroom or Capture One) every time a new camera model is released
- Completely unsupported in web browsers and standard operating system image viewers without specialized raw codecs
- Larger file sizes than in-camera JPEGs, requiring more storage space and processing power
