We can squeeze more out with oxipng/oxipng, I can open a PR if you like.

That would be great @hugovk! Thanks 😊

Coming up!

We should also probably do something similar for added/modified images as a GHA on PRs. But that's totally up to you to implement that 🙂 running oxipng on the repo manually would already be very useful

Yep, here's two methods.

Enable https://imgbot.net/ for the repo and it'll open PRs with optimised images.

• Runs after merging original images.

Add https://github.com/oxipng/oxipng to .pre-commit-config.yaml (looks like https://pre-commit.ci/ is already enabled for the repo).

• Will update PRs before merge.
• Will also catch other pre-commit autofixes like Prettier.
• If you use pre-commit (or prek) locally, it makes pre-commit run --all-files slower by ~1m48s. But normal git commit will only check modified files.

Which do you prefer?

I'm leaning towards adding oxipng to .pre-commit-config.yaml, and it may be a good opportunity start using prek instead of pre-commit too! Up to you which one to choose!
