Mac Imageoptim Auto

Oct 13, 2020

I want to automatically convert pdf to jpg, and compress jpg.

First, need to install ImageOptim, and put in Application folder.

Then install ImageOptim-CLI to run ImageOptim in command line.


# convert pdf to jpg
sips --resampleWidth 1024 -s format jpeg *.pdf --out dist/

# compress all jpg in dist folder
imageoptim dist
