Ecom Image OptimizerAliExpress Image Size
Square, white, and free of any promotional overlay.
Last updated
AliExpress asks for main images of at least 800 × 800 px, which is also the threshold that enables zoom. A square 1:1 composition is the safest choice; ratios up to about 1:1.3 are tolerated, but square displays most predictably across the mobile app and desktop site.
The main image is expected to sit on a pure white background at RGB 255/255/255. Scene-based and gradient backgrounds are generally restricted to certified brand flagship stores rather than ordinary shops.
Content rules matter as much as dimensions here. Watermarks (including your own store name or contact details), promotional text such as discount claims, price tags and parameter callouts are not permitted on the main image. Brand logos, where allowed, are expected to be small and consistently placed.
AliExpress publishes the authoritative version of these rules inside Seller Center, and category-level exceptions are common. Treat the figures below as the general baseline and confirm against your own category before a large upload.

Frequently asked questions
What size should AliExpress product images be?
At least 800 × 800 px, which is also the point where zoom becomes available. Square is the safest ratio; 1000 × 1000 px is a comfortable default that clears the minimum without producing heavy files.
Does AliExpress require a white background?
The main image is expected to be on a pure white background at RGB 255/255/255. Gradient and scene backgrounds are generally limited to certified brand flagship stores rather than ordinary shops.
Can I put a watermark on AliExpress images?
No. Watermarks including store names and contact details are prohibited on main images, as are promotional overlays, price tags and specification callouts.
What file format does AliExpress accept?
JPEG and PNG. JPEG is the practical choice for photography; PNG only where you need transparency, though the main image should be on white in any case.
Are the rules the same for every AliExpress category?
No. Category-level requirements vary, and Seller Center holds the authoritative version. Check your own category before running a large upload rather than relying on general guidance.
