Handy command line tool for shrinking PNG images using the TinyPNG API
npm install -g tinypng-cliTo use TinyPNG CLI, you need an API key for TinyPNG. You can get one at https://tinypng.com/developers.
TinyPNG CLI allows you to provide your API key in two different ways. The more convenient one is to save the API key into a file called .tinypng within your home directory. The other way is to provide it as an option while running the CLI.
tinypng demo.png -k E99a18c4f8cb3EL5f2l08u368_922e03To shrink all PNG images within the current directory.
tinypng .To shrink all PNG images within the current directory and subdirectoies, use the -r flag
tinypng . -rTo shrink all PNG images within a specific directory (assets/img in this example), you may run the following command.
tinypng assets/imgNeed to limit the number of compressions at a time? Use the -m, --max flag:
tinypng assets/img --max 100You may also provide multiple directories.
tinypng assets/img1 assets/img2To shrink a single PNG image (assets/img/demo.png in this example), you may run the following command.
tinypng assets/img/demo.pngYou may also provide multiple single PNG images.
tinypng assets/img/demo1.png assets/img/demo2.pngTo resize an image, use the --width and/or --height flag.
tinypng assets/img/demo.png --width 123
tinypng assets/img/demo.png --height 123
tinypng assets/img/demo.png --width 123 --height 123By default, this tool caches a map of all compressed images sent to the API in ~/.tinypng.cache.json. To change this directory, use the -c, --cache flag:
tinypng . -r --cache /path/to/myCache.jsonIf you want to forcibly recompress assets, use the --force flag. For a dry run output of all files that will be sent to the API, use the --dry-run flag.
That's it. Pretty easy, huh?
