Three ways 1688 sellers get rejected
- Right size, wrong background — main images are usually pure white. A light grey or lifestyle backdrop reads as non-compliant, so exports fill #FFFFFF.
- Over the file ceiling — No file ceiling is published, so your seller dashboard decides. An image over the cap is rejected even at the correct size, so cut the bytes first.
- Stretched aspect — forcing a 3:4 source into 1:1 distorts the product. Scale proportionally, then pad or center-crop.
