TinyPNG CLI

Handy command line tool for shrinking PNG images using the TinyPNG API

Installation

npm install -g tinypng-cli

Preamble

To use TinyPNG CLI, you need an API key for TinyPNG. You can get one at https://tinypng.com/developers.

Usage

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_922e03

To shrink all PNG images within the current directory, you may run one of the following commands—both do exactly the same.

tinypng
tinypng .

To shrink all PNG images within the current directory and subdirectoies, use the -r flag

tinypng -r

To shrink all PNG images within a specific directory (assets/img in this example), you may run the following command.

tinypng assets/img

You may also provide multiple directories.

tinypng assets/img1 assets/img2

To shrink a single PNG image (assets/img/demo.png in this example), you may run the following command.

tinypng assets/img/demo.png

You may also provide multiple single PNG images.

tinypng assets/img/demo1.png assets/img/demo2.png

To 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 123

That's it. Pretty easy, huh?
