Daraz main images need a square shape and a clean white background. This tool tests your photo against those rules using its real pixels, so you can see a problem before a listing goes up.
The photo never leaves your phone or computer. Fix All pads the image to a white square at 1024 pixels and compresses it to fit under 1MB. It cannot repaint a grey background, so the report tells you when a new shot is the better fix.
What the checker tests
It measures the shape, the shortest side, the file weight and the format, and it samples the pixels around the edge of the photo to test for pure white (#FFFFFF). It also flags transparent areas, which can show up as black in a listing.
It cannot read text, logos or watermarks on the photo, so those rules appear as a reminder beside the report. Check them with your own eyes.
Where these rules come from
The 1:1 shape, white main image, JPEG or PNG format, 1024 pixels and 100KB to 1MB come from seller sources quoting the Daraz Image Guidelines. We could not open the guideline on a Daraz page, so we mark these as unconfirmed. Daraz words some of them as recommendations, so check Seller Center if your upload is refused.
