JPEGS3 compresses JPEG better and faster than legacy tools with no visual loss
Two-stage compression
After a visual-lossless pass, JPEGS3 can run Lepton compression on the resulting JPEG, squeezing out another ~20% with zero data loss. The file decompresses back to the exact same JPEG, bit for bit. The savings compound automatically.
Benchmark
Tested on a 2023 MacBook Pro M2. Same source file, default quality settings for each tool.
