BPG at a glance
BPG
BPG arrived in the mid-2010s when image engineers were looking for better post-JPEG compression before AVIF and JPEG XL had ecosystem momentum.
Xfig at a glance
Xfig
Xfig began in 1985 and accumulated decades of maintenance and export tooling, which made the .fig format a durable bridge between interactive diagram editing on Unix systems and downstream conversion to PostScript, PDF, and other outputs.
