Upload your main product image and see if it meets Amazon's rules: pure-white background, product fill, resolution and shape. Then run an optional AI check for text, logos, badges and props.
zonfy creates a complete, Amazon-ready image gallery and premium A+ Content from a single product photo, so you skip the editing and get straight to listing.
How to use it
Drag in the JPEG, PNG or WebP you plan to use as your first listing image. The pixel checks run in your browser, so nothing is uploaded.
Each row is a pass, warning or fail, with a plain explanation and a specific fix. The background map shows exactly which edge pixels aren't pure white.
Optionally scan for added text, logos, badges and props. Then fix the issues yourself or with our free Image Fixer, and confirm in Seller Central.
Your main image is the one shoppers see in search results, so Amazon holds it to stricter rules than the rest of your gallery. The background must be pure white, meaning RGB 255, 255, 255 (#FFFFFF). The image should show only the product being sold, as a real photo, with no added text, logos, watermarks, badges, borders or props that aren't included. Amazon's style guide also asks for the product to fill about 85% of the frame.
The most common reason a clean-looking photo gets flagged is the near-white trap. A background at RGB 245 or 250 looks perfectly white on screen, but it isn't pure white. Studio shots, phone photos and JPEG compression often leave the background a few points off. This checker samples the outer border of your image pixel by pixel and tells you how much is truly 255 and how much is only near-white.
Size matters too. Images with at least 1000 px on the longest side support zoom, and 1600–2000 px gives a sharper result. Square images display best in search and on mobile. Treat this tool as a pre-flight check: Amazon makes the final decision, some categories (apparel, jewellery and media, for example) have their own rules, and you should always confirm the image in Seller Central after uploading.
Because it is probably near-white, for example RGB 248, 248, 248, rather than pure white (255, 255, 255). The difference is invisible to the eye but not to automated checks. Fill the background with exactly #FFFFFF in your editor, or use the free Image Fixer to force it.
Amazon's guideline is that the product should take up about 85% of the image frame. We measure the bounding box of the non-white pixels and compare its longest side with the frame. A product that is much smaller than that looks tiny in search results.
At least 1000 px on the longest side so hover-zoom works. 1600–2000 px square is a common, safe choice. Amazon lists JPEG, TIFF, PNG and GIF as accepted formats, with JPEG preferred.
The pixel checks run entirely in your browser, so your image never leaves your device. If you click "Run AI check", we send a downscaled copy (max 1024 px) for analysis. It is processed in memory and not stored.
No. This is a pre-flight check based on Amazon's published image rules. Amazon makes the final call, enforcement can vary by category and marketplace, and AI can miss things. Always confirm in Seller Central after uploading.
Not as overlays. Added text, logos, watermarks and badges aren't allowed on the main image. A logo or text that is physically printed on the product or its packaging is fine. Save feature callouts and infographics for your secondary images.
