About ShopPrep

ShopPrep is a free tool for marketplace sellers. It exists because one job — turning product photos into correctly-sized listing images — was scattered across generic resizers, paid apps and single-photo tools, none of them built around how Etsy, Shopify, eBay and Amazon actually display photos.

So ShopPrep does the whole job in one pass: batch resize and crop to each marketplace’s real sizes, a thumbnail safe-zone preview so search crops never surprise you, compression, keyword filenames, and one ZIP at the end. It runs entirely in your browser, which keeps it free, instant, and private — your photos are never uploaded anywhere.

ShopPrep is not affiliated with Etsy, Shopify, eBay or Amazon. Marketplace names are used only to describe the image sizes their platforms recommend. Sizes are checked against each platform’s published seller guidance; marketplaces can change their requirements, so treat our guides as a starting point and check the platform if a listing is rejected.
