No, your image credits won't get deducted for images you've already resized previously. This applies to merchants who are on a Pay-as-you-go plan as well (i.e. you don't have to pay for the resized images twice).
How Does It Work?
When you resize images using our Photo Resize app, the app will mark all resized images as 'paid' internally. This allows us to track which images have already been resized. This means that if you decide to change your image settings and resize the same image again, you won't have to pay for it or use up your image credits.
Benefits of Using Our Photo Resize App
By using our Photo Resize app, you can save time and money by avoiding the need to pay for the same images multiple times. This is especially beneficial for those on a plan with limited image credits or for those on a pay-as-you-go plan.
Exceptions
The only exception to this is if you replace the photo in your product. Our Photo Resize app tracks images based on the photo's ID, which we retrieve from Shopify's system. If that has changed, we won't have the means to track that image as resized by our app.
