Check your photo against Zalando's rules.
Zalando sets rules for the main image that can be measured from the photo: background colour. Drop a photo to see which ones it meets. It runs in your browser; nothing is uploaded.
Choose a marketplace and a photo.
Rules come from each marketplace's own help pages, summarised in the guides (checked 24 September 2026). Size, file size and format are checked as well.

How each rule is measured.
- Background colour
- The background colour is the median of a thin band along all four edges. A pure-white rule passes only when that band is RGB 255, 255, 255; near-white values such as 253 are reported with their exact colour.
- Scene photos
- Room and lifestyle photos have no plain background to measure against, so fill, edges and shadow are marked as not measured rather than guessed.
