Resizing a square image to a rectangle with a fixed aspect ratio [duplicate]

Question

I have a very large batch of images that I need to resize. I am new to Photoshop (have used Elements for years) and I am unsure how to do this. Basically, all the images are currently 2000 x 2000. They are product silhouettes so the item is in the middle, surrounded by white space. I need to resize them to 1768 x 2160 and keep an aspect ratio of 140 x 171.

Is there any way to do this. If so, step by step directions would be amazing! I don't want to make any errors.

Answer 1

This is easily accomplished with an Action which can be applied to a batch of images.

• Make a source folder with only the original images and an empty destination folder for the finished images.
• Open one of the original images in Photoshop.
• Open the Actions panel and create a folder for your action using the Create new set button in the bottom.
• Click the Create new action button and choose the set you just created as Set. Click the Record button to start recording the action.
• Resize the image to 1768 x 1768 px, using Image > Image Size with Resample Image turned on.
• Extend the canvas to 1768 x 2160 px, using Image > Canvas Size, set Canvas extension color to White.

• Use the Stop playing/recording button in the Actions panel to stop recording. Your action should look something like this:

  

• Close the image without saving.
• Now where are ready for batching. Choose File > Automate > Batch.

• The Batch dialogue could be setup as I did here:

  

• Choose the set and action you just created. Choose the proper source and destination folder. Suppress dialogs and warnings.
• File naming can be done in many ways. Here I've chosen to have the original filename followed by "_1768x2160" and the extension.
• Click OK and Photoshop should start processing your source images.
