![]() PNG - PNG compression type can be lossy compression or lossless compression. JPG - For the JPEG image formats, JPG quality is 1 (lowest image quality and highest compression) to 100 (best quality but least effective compression). Different image formats use different optimization options. The image format can be JPG, PNG, GIF, SVG, WEBP or DDS.Ģ. ![]() Click the "Choose file" button to select a file on your computer or click the dropdown button to choose an online file from URL, Google Drive or Dropbox. tests/files/rgb_16_should_be_grayscale_8.1. tests/files/rgb_16_should_be_grayscale_8.png' ranĥ.16 ± 0.58 times faster than 'optipng -o 4 -simulate. tests/files/rgb_16_should_be_grayscale_8.png ![]() Range (min … max): 100.2 ms … 160.4 ms 23 runsīenchmark #2: optipng -o 4 -simulate. tests/files/rgb_16_should_be_grayscale_8.png'īenchmark #1. tests/files/rgb_16_should_be_grayscale_8.png' ranġ.97 ± 0.25 times faster than 'optipng -simulate.

Oxipng is open-source software, distributed under the MIT license. Other contributions (such as improving documentation or translations) are also welcome via GitHub. However you do not need to be a Rust developer to contribute. To submit a fix with the bug report, it is preferred that you do so via pull request, Please include as many details as possible. Bug reports can beįiled via GitHub issues. ContributingĪny contributions are welcome and will be accepted via pull request on GitHub. This also served as an opportunity to choose a more modern, safer language (Rust). Which would be very difficult to do within the existing C codebase of OptiPNG. The core goal of rewriting OptiPNG was to implement multithreading, The name has been changed to avoid confusion and potential legal issues. (OptiPNG has since released a new version, after Oxipng was first released.) Which was assumed to be dead as no commit had been made to it since March 2014. Oxipng began as a complete rewrite of the OptiPNG project, Passing it, along with an input filename, into the You should then have access to all of the library ![]() Then extern crate oxipng in your project. To do so, simply add oxipng as a dependency in your Cargo.toml, Library UsageĪlthough originally intended to be used as an executable, oxipng can also be used as a library in More advanced options can be found by running oxipng -h. s can be used as a shorthand for -strip safe. You can also pass a comma-separated list of specific metadata chunks to remove. "All" removes all metadata that is not critical Will never affect rendering of the image. Ĭan save a few kilobytes if you don't need the metadata.
