Compress screenshots from the Finder on macOS without TinyPNG

For the past few years, I have been using an Automator script that would compress PNGs using tinypng-cli that I could call from the Finder.

I recently learned how TinyPNG compresses PNGs: it calls out to pngquant, which is an open-source program that you can download yourself. Not using TinyPNG means I no longer need to send my images to a third-party, and I no longer need a network connection to compress images.

To do that, you will first have to install pngquant:

brew install pngquant

Then, get the shortcut: https://www.icloud.com/shortcuts/a63b010001c547b196f89eaa6262e9ef

It looks like this:

Image Not Showing Possible Reasons

The image was uploaded to a note which you don't have access to
The note which the image was originally uploaded to has been deleted

Finally, go to your Finder, and click the three dots ("More…"):

Image Not Showing Possible Reasons

The image was uploaded to a note which you don't have access to
The note which the image was originally uploaded to has been deleted

Turn on pngquant as a Quick Action:

You can now compress PNGs straight from the Finder:

Same with JPEG images
