Integration

I have set up a right click menu in macOS Finder that allows me to right click any GIF and optimise it.

You can also use ImageOptim or similar GUI wrappers for gifsicle.

How did you set up a right-click command for this?

I used ContextMenu I've been using that for years.

But there's also the newer ServiceStation and another alternative fiScript.

hmm, I'm having some difficulty setting this up with ContextMenu.

langui.ContextMenu/Actions/optimize....cmaction/main.sh: line 1: gifsicle: command not found

I'm very unversed in bash, but running the same command from terminal worked like a charm. What am I doing wrong here?

no worries! here is what I use.

  • I have variables for the FILEname (minus .gif extension) and PARENT folder.
  • I call installed gifsicle so have to run out of sandbox.
  • O3 with careful is just to help with compatibility of resulting GIF
  • this will spit out anim.opt.gif next to your original anim.gif
FILE=`basename "$@" .gif`
PARENT=`dirname "$@"`
/usr/local/bin/gifsicle -O3 --careful "$@" > "$PARENT/$FILE.opt.gif"

Worked like a charm thank you!

There is also a nice (free) GUI app for Mac called ImageOptim that I enjoy using. Lots of great options!
