Here are some simple steps to automate converting and image from one format to another.
- Open the first image you want to convert.
- In Photoshop go to ‘Window’=>’Actions’.
- Click on the ‘Create new action’ button and give it a meaningful name, something like jpg2png will suffice.
- Save the image you opened manually.
- Once done, click on the stop button.
- Go to ‘File’=>’Automate’=>’Batch’.
- Under the ‘Actions’ drop down select the one you just created and click ‘Go’.
