How to use MacOS automator to automatically convert images directly from finder

Awesome, work great! If i want to compress webp @ 80% how can i choose it?
And if i want to add other type files, how to please?

[justinjbird]

Since writing this post I had the same need, so I've rewritten it. I might update the post one day but here it is for now...

for file
do
  fileNoPath=$(basename $file)
  newFile="$(dirname $file)/${fileNoPath%.*}.webp"
  /opt/homebrew/bin/cwebp -lossless "$file" -o "$newFile"
done

This gets the basename of the file, then defines the path for the new file and then uses the new path in the cwebp command. I haven't included the rm command in mine but you can add that in to remove the original, same as in the original example. As for compressing, have a look at the options for cwebp and see which one suits your needs and simply add it to the command line after -o "$newFile".

To solve this question, you would only have to add -q 80 where -lossless is written.

Hello Guys, I want to keep both PNG and WEBP file. Please guide me to modify the code accordingly.
Thanks.

[justinjbird]

Hi @akash-chadha the command in the original post that removes a file is rm "$file" so you could just get rid of that line and it will create the webp file alongside the png

[akash-chadha]

Thanks for the reply, @justinjbird. After removing the line, I'm encountering an error. The action "Run Shell Script" is showing: "zsh:6: no such file or directory: /opt/homebrew/bin/cwebp". Please assist me in resolving this issue so that my automation can function properly.

[justinjbird]

That means that the script can't find the application cweb that means either a) you haven't installed it or b) it's installed at a different path to mine. Just re-reading my post, the prerequisite about this wasn't very clear so I've elevated it to the top and rewritten it. Have a read, see if it helps you. Also note that I am using an Mx mac and so homebrew is installed at a different path to an intel mac. If you are using homebrew you can check the required path by running which brew and that's the path you should use. Hope that helps...

Hi Justin thank you very much for such an excellent guide, this gave me many ideas for quick actions in many repetitive tasks that I have, now to adjust the script and define that it is at 80% quality would only have to change -lossless to -q 80 and ready so the webp images are at 80% quality with respect to a rating system from 0 to 100.

[justinjbird]

yeah I have been messing with a few other things like trying to have a task that decrypts password protected pdfs, one for images that sets resolution, any useful hacks you've come up with?

Hi! I'm way late to this party, but I have a question. I regularly update files on a website and have an automator action to rename and resize them. I've incorporated this script (awesome work btw) into the workflow, but sometimes the files are .png and sometimes they're .jpg. When the script runs, sometimes it comes back with this: filename.png.webp or filename.jpg.webp and I'm trying to figure out how to make it drop the extra extension. My script as is now:

for file
do
ext=${file##*.}
if [ "$ext" = "jpg" -o "png" ];
then
/usr/local/bin/cwebp -lossless -quiet "$file" -o "${file.jpg}.webp"
rm "$file"
else
fi
done

And I know there's the line /usr/local/bin/cwebp -lossless -quiet "$file" -o "${file.jpg}.webp"
that control the rename, but I cannot figure out how to add a wildcard or an option to disregard whatever original file extension is there. Will you please help? Thanks.

I figured out a code to get my automator action to do what I want: take whatever image type that isn't webp and convert it to webp and then rename the file to the original filename.webp and then remove the original image. It does not resize images. I'll put it here for anyone else who might need it.

for f in "$@"

do

/usr/local/bin/cwebp -lossless -quiet "$f" -o "${f%.*}.webp"
rm "$f"

done

[justinjbird]

Missed this comment @DarkAthena. I have over time updated mine to do similar, but looking at your code I seem to have got there in a bit of a roundabout way...

for file
do
  fileNoPath=$(basename $file)
  newFile="$(dirname $file)/${fileNoPath%.*}.webp"
  /opt/homebrew/bin/cwebp -lossless -quiet "$file" -o "$newFile"
done

Updated post with credit!

This is Awesome!
Is there a way to make this process folders of images?
I"m reading through the comments, but after a quiet page search I didn't find 'folder' so not sure anyone else ever asked?
