I like to use oxipng to optimize PNG (and other) images.

There’s a pre-commit hook available, therefore enforcing it is a breeze:

     yaml
     
   
- repo: https://github.com/shssoichiro/oxipng
  rev: v9.1.3
  hooks:
    - id: oxipng

Surely you could run it in github actions as well, if you don’t use pre-commit.com.

If I need to use it as an one-off, I can either run the oxipng binary directly, or use a web version such as Squoosh (via Simon Willison).
