Preface

This article describes how I use docker to optimize my own image files.
Directly shrink the image files in the directory, and optimize the graphics with one line of command.

This is the repo I created on GitHub, download it and build your own image to use it

Please note that the original image will be changed directly!!

Build your own image can use the following commands:

docker build -t optimize-image .

I use this command to update image files with text content

docker run --rm -v ${PWD}:${PWD} optimize-image ${PWD} -mw 900 -q 80

Please note that you have a backup of the original image, I use this command to update the super large pattern on my website

docker run -rm -v ${PWD}:${PWD} optimize-image ${PWD} -mw 1620 -q 20

docker run -v ${PWD}:${PWD} optimize-image ${PWD} -mw 1620 -q 20
