Pixelmator Tip #54 – How To Quickly Add Watermarks To Your Images

Ninja Share:

One of the really awesome tools we use regularly is the Automator application in your Mac. It is one of the best tools to automate some of the more simple but repeatable tasks very quickly.

In this tutorial we will show you how to set up an automator action to quickly add watermarks to your images using Pixelmator.

Here is our final image with our pixelmator templates ninja watermark added using our automator action.

Note: There are some limitations to automator actions, and we will talk through those as we go through the tutorial.

Step 1

Go to the applications folder in your Mac, and open the Automator application. The icon is a robot holding a metal tube.


Step 2

When the dialog opens up, select the type of document you want to create. As you can see Automator allows you to create a number of different types of actions such as creating a calendar event, creating a folder action, or even triggering a print event.

For the sake of this tutorial, we will create an Automator Application, so select this option and hit Choose.


Step 3

Now in the search dialog (with the magnifying glass icon), type in the name of the application you want to automate. In our case type in Pixelmator and hit return.

This gives you the list of options available for Pixelmator, which we can automate.

Scroll down to the Watermark Images option and hit return.


Step 4 – Setting up the watermark action

Once you opened up the Watermark Images option, you get two sequential actions to run one after the other.

The first action is to copy / replace the image you provide and place it somewhere on the computer. We left this to the default, which places the copied and watermark image onto the desktop.

The second action will place a given watermark image into a preferred location on the image provided.


For our second action, we used our ninja watermark and placed it in the bottom right hand corner of the image provided.


Next, save the action (CMD+S), which will save the action as a mac application.

We called our application – Watermark.app and saved it to our desktop for easy access.

Step 5

Here is our test image we want to watermark from one of our useful photographic resources.


Now here is our Watermark.app automator action, and our test image in our desktop.


All you need to do is drag and drop the test image onto the Watermark.app file, which then should produce a copy of your test image with your watermark.

Additional Tips/Notes:

  • Keep the watermark image size small – ideally no bigger than 150x150px. We can’t control the size settings of the watermark image relative to your test image – this will be more of a trial and error to get this right.
  • Avoid small text in your watermark image – they won’t show up well.
  • Ideally use white color and with some transparency for your watermark images – you may notice we did this for our final image.
  • To preserve transparency in your watermark images – ensure you save them as PNG files.
  • Make sure that you finalise your watermark images as needed before you add them to this action – especially for things like rotating the image, color, transparency etc.


Excellent, you should now be able to create your own watermark automator action to help you quickly create watermark images using Pixelmator.
