how to use (linux)

install the .deb via dpkg -i {name_of_the_downloaded_package}.deb

by default it gets installed to /opt/{lib}mozjpeg/bin/

so now you can do /opt/mozjpeg/bin/cjpeg -quality 80 foo.bmp > bar.jpg

how to use (windows)

extract the zip, open cmd.exe and navigate there via cd {folder}

now you can do cjpeg -quality 80 foo.bmp > bar.jpg
