Yes, all images that have been resized and replaced in your store will remain resized even if you cancel your plan.
If you’re on a Free or Pay-as-you-go plan, we will store the original product images we have resized for 7 days from the moment they were resized.
After 7 days, you will no longer have the option to restore the images to their original files unless you upgrade to a paid plan before the photos expire.
