SHEIN · Main product image
Item	Requirement	Notes
Target size	800×1000 px	Exact pixels — the export has to match this number, not come close
Aspect ratio	4:5	Simplified from the target size. If your source differs, pad or center-crop — never stretch
Min width	Not listed	Smallest source the platform accepts; below this an image can be flagged as blurry
Max file size	Not listed	The export must stay under this size or the upload gets rejected
Background	Pure white (#FFFFFF)	Fill padding with #FFFFFF on white-background specs so no grey edge shows
Formats	JPG / PNG	Exporting in one of these formats is the safe bet

Making an image for this spec: 5 steps

Start from a source at least 800 px wide. A soft photo stays soft after scaling — the tool cannot invent detail.
Scale proportionally to 800×1000 (4:5). If the aspect differs, pad or center-crop — never stretch.
Fill the padding with pure #FFFFFF, then check for leftover grey edges or semi-transparent pixels.
Export JPG / PNG; No file ceiling is published, so your seller dashboard decides. The tool protects the ceiling first and sharpness second.
Verify: the output must be exactly 800×1000 px, zero pixels off, and the byte count must sit under the cap.

FAQ

Is 800×1000 mandatory?

The platform names 800×1000 px for Main product 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.

No published ceiling — should I still care?

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. This slot has no published ceiling, so your seller dashboard decides. If you want a target anyway, aim under 500 KB — most slots are far more generous.

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.
