Guetzli-generated images are typically 20-30% smaller than\nimages of equivalent quality generated by libjpeg. Guetzli generates only\nsequential (nonprogressive) JPEGs due to faster decompression speeds they offer.\n\n[![Build Status](https://travis-ci.org/google/guetzli.svg?branch=master)](https://travis-ci.org/google/guetzli)\n\n# Building\n\n## On POSIX systems\n\n1.  Get a copy of the source code, either by cloning this repository, or by\n    downloading an\n    [archive](https://github.com/google/guetzli/archive/master.zip) and\n    unpacking it.\n2.  Install [libpng](http://www.libpng.org/pub/png/libpng.html).\n    If using your operating system\n    package manager, install development versions of the packages if the\n    distinction exists.\n    *   On Ubuntu, do `apt-get install libpng-dev`.\n    *   On Fedora, do `dnf install libpng-devel`. \n    *   On Arch Linux, do `pacman -S libpng`.\n    *   On Alpine Linux, do `apk add libpng-dev`.\n3.  Run `make` and expect the binary to be created in `bin/Release/guetzli`.\n\n## On Windows\n\n1.  Get a copy of the source code, either by cloning this repository, or by\n    downloading an\n    [archive](https://github.com/google/guetzli/archive/master.zip) and\n    unpacking it.\n2.  Install [Visual Studio 2015](https://www.visualstudio.com) and\n    [vcpkg](https://github.com/Microsoft/vcpkg)\n3.  Install `libpng` using vcpkg: `.\\vcpkg install libpng`.\n4.  Cause the installed packages to be available system-wide: `.\\vcpkg integrate\n    install`. If you prefer not to do this, refer to [vcpkg\u0027s\n    documentation](https://github.com/Microsoft/vcpkg/blob/master/docs/EXAMPLES.md#example-1-2).\n5.  Open the Visual Studio project enclosed in the repository and build it.\n\n## On macOS\n\nTo in",
