Step 8: Go to File → Save, and give the service a name in the Save service as box. This will create a 1920 x 1080 image since I’m working with 16:9 input. In my circumstances, I choose 1920, since I’m resizing 3840 x 2160 files. Step 7: In the Scale Images action panel, insert the width that you’d like to resize to. I choose not to do this, but if having backups of your images prior to resizing is important to you, it’s something to consider. Step 6: Automator will prompt you to add an add a Copy Finder Items action to preserve original files in a separate folder. Step 5: Under Actions select Photos, and drag Scale Images to the build area. Step 4: Under Actions (on the left) select Files and Folders, and drag Get Specified Finder Items to the build area (right side). Step 3: Choose image files in the Services receives selected drop down box. Step 2: Select Service for the document type. Here’s how you can create your own handy image resizing service using Automator. It’s easy to resize images in an app like Preview or Pixelmator, but using a service works better for me since it can batch resize multiple images in seconds, and it’s directly accessible from the Finder. Every day I use a handy service created with Automator to resize images exported from 4K footage to a smaller size.
