The AliExpress Product Image size (800×800px)
AliExpress asks for square product images and turns on its zoom magnifier once a photo reaches 800 pixels on each side, so 800x800 is the practical target for sellers who want buyers to inspect an item closely. The main image must be a true 1:1 square, and hitting 800px keeps the file light for shoppers browsing on mobile data across the many regions AliExpress serves, while still giving the zoom viewer enough detail to be useful.
Because AliExpress is a global, price-sensitive marketplace, the primary photo does heavy lifting in a dense search grid. AliExpress prefers a clean white or very light background with the product centered and filling most of the frame, and it discourages heavy promotional text or watermarks on the main image. Resizing a crisp, centered shot to 800x800 makes your listing look consistent with the platform's catalog standards and helps it stand out among thousands of similar items.
You can upload additional images for variations, scale, and detail shots, and keeping them all at 800x800 gives your listing a tidy, uniform gallery. Larger images are allowed and can look sharper on desktop, but 800px is the reliable floor that guarantees the zoom experience without bloating load times for buyers on slower connections. Everything here resizes 100% in your browser with no upload and for free, so your photos stay private. AliExpress's image rules and thresholds change over time, so verify the current spec before listing.
