xTinyPNG CLI

Handy command-line (CLI) tool for shrinking PNG/JPEG images using the TinyPNG API

Installation

npm install -g xtinypng-cli

To install the latest code, in the event that the current repository is ahead of the published version

npm install -g mathieu-aubin/xtinypng-cli

Requirements

To use xTinyPNG CLI, a key for the TinyPNG API is required.Getting one is simple and quick, from TinyPNG's website.

Usage

xTinyPNG CLI supports the following three (3) different methods of passing your API key

Environment variables

The most convenient method, according to me, is to use environment variables. - XTINYPNGKEY - TINYPNG_KEY - TINIFY_KEY (for compatibility with [_Tinify](https://www.npmjs.com/package/tinify))

RC-type File

Save your API key into a file, within your $HOME directory, named either - .xtinypng - .tinypng

CLI Argument

Useful for scripting/automation purposes, provide the API key as a CLI argument with -k/--key flags

xtinypng -k E99a18c4f8cb3EL5f2l08u368_922e03 demo.png

Examples #### (limited see help)

To shrink all PNG/JPEG images within the current directory, you may run one of the following commands -- they do exactly the same.

xtinypng
xtinypng .

To shrink all PNG/JPEG images within the current directory, recursively, use the -r/--recursive flags

xtinypng . -r
xtinypng -r /somefolder/images

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

xtinypng assets/img

You may also provide multiple directories.

xtinypng ./assets/img1/* assets/img2

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

xtinypng assets/img/demo.png

You may also provide multiple single files

xtinypng assets/img/demo1.png ./assets/img/demo2.png

To resize images, use the --width and/or --height flags. Short versions of those also exist as -H and -W

xtinypng assets/img/demo.png --width 123
xtinypng assets/img/demo.png --height 123
xtinypng -W 123 --height 123 filename.jpg

A resize method is also available when resizing with --method or -m. Depending on the method WhichYouWish to perform, a different combination of either height/width will be required.

xtinypng --height 640 -m scale filename.png
xtinypng assets/img/demo.png -W 200 -H 140 -m fit
