See every featureImage Optimization helps Shopify store owners improve page load speed and search engine visibility by compressing product images and generating AI-powered alt text. Large, unoptimized images slow down your store and hurt your search rankings. Missing or poor alt tags make your products harder to find and less accessible.

You can also restore an individual original image or in bulk.
