Coverage counts what each App Store listing names. Every feature, checked off app by app, is in Shoplist.
See every featurePixelLean converts product images to WebP to reduce image file sizes. Set a target size, minimum quality and maximum dimensions, then process images in the background. Original files remain available for restore, and converted images keep their original basename with a .webp extension. Track optimization progress and review images that need attention from one dashboard.
Slimpix compresses your product images to WebP or JPEG at the quality and maximum size you choose, so pages load faster. Every original stays in your files, and Restore puts the exact original back in the same position and on the same variants. Images that would barely shrink are skipped and left as they are. A report shows what was saved per product.
