Spec values
This is the platform's requirement for the slot, and the tool exports straight from it: exact pixels, KB ceiling checked, #FFFFFF fill on white-background specs.
| Item | Requirement | Notes |
|---|---|---|
| Target size | 750×750 px | Exact pixels — the export has to match this number, not come close |
| Aspect ratio | 1:1 | Simplified from the target size. If your source differs, pad or center-crop — never stretch |
| Min width | 750 px | 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 | Any background | 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 750 px wide. A soft photo stays soft after scaling — the tool cannot invent detail.
- Scale proportionally to 750×750 (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; 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 750×750 px, zero pixels off, and the byte count must sit under the cap.
FAQ
Is 750×750 mandatory?
The platform names 750×750 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.
