Start from a source at least 480 px wide. A soft photo stays soft after scaling — the tool cannot invent detail.
Scale proportionally to 480×480 (1:1). If the aspect differs, pad or center-crop — never stretch.
Treat the background to suit the product, and keep it from competing with the item.
Export JPG / PNG; The file must stay under 3072 KB. The tool protects the ceiling first and sharpness second.
Verify: the output must be exactly 480×480 px, zero pixels off, and the byte count must sit under the cap.

FAQ

Is 480×480 mandatory?

The platform names 480×480 px for SKU / carousel preview image, and exporting at that size is the safest path. Your source can be larger — the tool scales it down. Uploading a non-conforming size invites a second compression pass, which shows up as grey edges or mushy detail.

What if my file is over 3072 KB?

The tool compresses to the ceiling automatically: JPEG quality first, downsampling if the quality floor is still too big, and it reports "quality floor reached" when that happens. The cap is 3072 KB, about 3.00 MB.

Can I use a format that is not JPG / PNG?

The platform lists JPG / PNG; exporting in one of those is the safe bet. Pushing WebP into a slot that only lists JPG / PNG risks a rejection or a broken thumbnail, so convert first.
