MozJPEG
JPEG encoder that patches libjpeg-turbo to produce smaller JPEG files at the same visual quality, usable as a drop-in libjpeg library.
MozJPEG is a C library that patches libjpeg-turbo to encode JPEG files at smaller sizes for the same visual quality. It keeps the libjpeg API, so it can take the place of libjpeg in a program that uses that API. The project aims at graphics programs and image processing tools, which call the library; a cjpeg command-line tool is included as a demonstration. The source is built with CMake in the same way as libjpeg-turbo, and Windows builds can use vcpkg. The project is maintained by Mozilla on GitHub.
