Compression trade-offs
Each line shows what a higher encoder effort buys at the same visual distance.
The outlined line and point match your current effort. The vertical guide compares every effort at the selected distance.
Distance quantifies visual distortion using the psychovisually robust Butteraugli metric, where zero represents mathematically lossless compression.
Effort controls the amount of computing power (CPU and memory) used to optimize compression efficiency while maintaining the target distance.
Encoding Time: Images were compressed using libjxl 0.12 on a 12-Core (8 Performance & 4 Efficiency), 96GB, M2 Max MacBook Pro on July 11, 2026.
