Oxipng is a multithreaded lossless PNG compression optimizer. It can be used via a command-line interface or as a library in other Rust programs.
Oxipng began as a complete rewrite of the OptiPNG project.
This is free and open source software.
Key Features
- Optimization – The default (-o 2) is sufficiently fast on a modern CPU and provides 30-50% compression gains over an unoptimized PNG. -o 4 is 6 times slower than -o 2 but can provide 5-10% extra compression over -o 2. Using any setting higher than -o 4 is unlikely to give any extra compression gains and is not recommended.
- Interlacing – -i 1 will enable Adam7 PNG interlacing on any images that are processed, i 0 will remove interlacing from all processed images. Not specifying either will keep the same interlacing state as the input image. Note: Interlacing can add 25-50% to the size of an optimized image.
- Strip – remove metadata info from processed images. This can save a few KB if the metadata information is needed.
- Cross-platform support – runs under Linux, Mac OS and Windows.
