How it sells itself

ImgPress Pro re-compresses your original product images so the files Shopify stores and serves are smaller and your storefront loads faster. Compress one image or run a bulk compression across many products at once. Each original is replaced with an optimized version, and a dashboard tracks images optimized and space saved. You set the quality with a slider, and the app never replaces an image with a larger file.

WebP Image Optimizer compresses your Shopify store's product images and theme files to WebP format, significantly smaller than JPEG and PNG with no visible quality loss. Optimize product images with one click for all products. Use the collections view for targeted optimization. Theme and banner images are supported with the same URL preserved so your theme keeps working without any changes.

Key points
  • Compress product images one at a time or in bulk
  • Keep JPEG and PNG quality while making files smaller
  • Reduce images to WebP for smaller files at the same quality
  • Track images optimized and total space saved on a dashboard
  • Optimize product images to WebP format in one click
  • Theme and banner images optimized with the same URL preserved
  • Upload any image and compress it instantly to WebP
  • Preview before and after, and approve each change before it goes live

How Shoplist compares apps

Store counts come from Shoplist’s crawl of Shopify storefronts, which detects the apps each store runs; they are as of Oct 13, 2026. Reviews, ratings, plans, features and integrations come from each app’s Shopify App Store listing. 28-day figures are labeled when estimated, and a figure that is missing or estimated never decides who leads.
