ListingPic

ListingPic is a free marketplace image checker for online sellers. It helps Etsy, Amazon, TikTok Shop, Shopify, eBay, and Walmart sellers check product photo dimensions, aspect ratio, crop risk, file type, and upload readiness before publishing.

The tool runs directly in the browser, so product photos are not uploaded to a server. Sellers can use it to avoid blurry images, unexpected thumbnail crops, low-resolution uploads, and marketplace-specific image issues before they publish a listing.
