winget install --id Shssoichiro.OxipngAbout Oxipng
Oxipng is a multithreaded lossless PNG/APNG compression optimizer. It can be used via a command-line interface or as a library in other Rust programs.
What's new in 10.1.1
- [Performance] Improve Bigrams performance, giving notably faster results at lower levels. - [Improvement] Change --np flag to also prevent conversion to indexed from other color types. - [Improvement] Improve support for recompressing ICC profiles with high compression ratios. - [Misc] Add warning when --ziwi exceeds --zi. - [Build] Further reduce size of binaries.
