Step 1 — find the exact cause
Rejections usually come down to one of: a non-white background, the product too small, resolution under 1000px, text or logos, or an unsupported file type like WebP.
Step 2 — fix and re-upload
Fix the flagged problems: replace the background with pure white, crop so the product fills the frame, re-export at 1000px+, remove any text, and save as JPEG.
Frequently asked questions
Why did Amazon reject my image without explaining?
Amazon's automated messages are often generic. Checking against each rule reveals the cause.
How long until my listing recovers after fixing?
Usually shortly after a compliant image is accepted, though re-indexing can take time.
Will re-uploading the same image work?
No. If it broke a rule, it will be rejected again.
