Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featureImgPress 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.
Zen Image Optimizer compresses and resizes the images already in your store. Each image is rewritten in place: the media ID and the CDN URL stay the same, so themes, links and indexed pages keep working without redirects. Before a bulk run you can preview the result on a sample of your own photos — measured in memory, with nothing uploaded.
- 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
- Catalogue scan — reads size of every product and Files library image, resumable,
- Savings estimate — shows what is optimizable and how much before anything runs
- Preview run — compresses 5 of your own images in memory to measure the real
- Bulk compression — JPEG, PNG and WebP with lossless, balanced or aggressive
