Upload one candidate image and get a transient white-main proof report for size, canvas shape, edge background, corner background, transparency, and manual review gaps. No login is required for the first check.
The public checker focuses on deterministic evidence that is easy to miss by eye. It intentionally leaves product truth and marketplace judgment to you.
Checks whether the candidate is large enough for zoom and detailed review.
Flags unusual aspect ratios before you treat the file as a main-image candidate.
Samples border and corner pixels for near-white background evidence.
Checks for alpha pixels that can indicate a non-final or unsafe export.
Calls out hands, props, overlays, label/logo accuracy, and Seller Central review as user-judgment items.
This first public checker is designed for acquisition and trust, not for hiding product risk.
Saving reports to account history stays behind login so users can control their own commercial assets.
Anonymous checks do not create storage objects, database rows, public share links, or long-lived report URLs.
The report is proof evidence before upload, not Amazon approval, legal certification, or Seller Central replacement.
Sign in when you want to save proof reports, review proof history, update manual confirmations, or delete old saved reports.
Use the requirements checklist to understand why the proof report focuses on white background, product-only framing, overlays, size, and manual review.
