Photoshop Tip #6 | Use Photoshop Actions to Batch Process Photos
11 November 2007 - 19:53
If you post images to websites with any frequency you’ll eventually realize that you end up doing the same routines time and time again to prepare photos for the web. For example you may always end up with a 200×200px square with a border and some padding, or each image you work with may have some specific information printed on it, or each one may need to be set to black and white, etc. What if I told you that you can get through an entire day’s worth of formating in just a few minutes? You’d want to find out how right? Of course you would.
Thankfully those creative folks over at Adobe know a thing or two about how to increase productivity. That’s why the built the functionality to create “actions” in Photoshop.
What are Photoshop Actions?
In Photoshop, actions are a set of recorded events. They range from selecting and using tools to re-sizing, changing colors, applying filters, all the way down to cropping and saving. The user creates the actions either by coding them in a script or recording them. Once the action is played back the recorded/coded events take place in the order they were saved and are applied to the current image.
Batch processing is the task of applying an action or set of actions to a set of images. So how do you batch process images? Simple, just follow the steps below.
Batch Processing with Photoshop
Imagine we have a group of photos that we want to turn into smaller web snaps for our travel blog. They are all big photos, with not much consistency from one to another:

Looking at the pictures we decided that for our blog we want to re-size them all, add a border with some padding, and then save the output to a separate file and close out of the original image.
Step One, Open the Image and Create an Action Set
To create a new action go to Windows > Actions to bring up the actions pallet and then select the icon that creates a new action. It’s located right next to the little trashcan and looks like the new layer icon.
We’ll create an action called Create Blog Post Card and hit the record button. What this does is follow us through the first creation of a blog post card image. It is important to remember that the events that are recorded will be applied to every image that is processed so we need to think carefully about what we are doing to our images.
For our purposes we are going to first re-size the image:

We set the image to 400px wide and didn’t pay attention to the height. You could if you want to, but for our purposes here it isn’t needed. Next we’ll add a border to the image by extending the canvas size:
And finally we’ll output the image to the web.
Stop the Recording
Once you have completed the process once you simply stop recording by pressing the stop button.
Start Batch Automation
Now that we have the action, it is time to batch process the images. To do this, select File > Automate > Batch from the file menu. To bring up the Batch Process window. Fill it out, run the process and your done!
