Amazon Main Image Checker
Check an Amazon main image before you upload it: how much of the background reads RGB 255, how much of the frame the product fills by area, and whether the size suits zoom. It runs in your browser, and can lift a slightly off-white background and reframe the product for you.

How this check reads Amazon's guidance
White means RGB 255
Amazon's seller guidance asks for a pure white background, RGB 255, 255, 255, on main images in most cases. Off-white grounds of 250 to 254 look white to the eye, so the check counts the exact value and shows you where it falls short.
85% of the area
Amazon's category style guides say the product must fill at least 85% of the image area. For a square product that means spanning about 92% of the side, not 85%, which leaves roughly 4% of clear space on each side.
Over 1,000 px each side
Amazon's Product photos FAQ accepts 500 to 10,000 px on the longest side and prefers more than 1,000 px on each side for zoom. Our working recommendation is a 2,000 px square master when the original supports it.

Amazon Image Checker: FAQ
What does Amazon ask for in a main image?
Amazon's seller guidance asks for a real photo of the product on a pure white background, RGB 255, 255, 255, in most cases, with the product filling about 85% of the frame. Its Product photos FAQ lists 500 to 10,000 px on the longest side and prefers more than 1,000 px on each side for zoom. Category style guides add their own rules, so check yours in Seller Central.
Is Amazon's 85% rule measured by side or by area?
By area. Amazon's category style guides for shoes and for clothing say the product must fill at least 85% of the image area. A square product spanning 85% of the side covers only 72% of the area; reaching 85% takes about 92% of the side. A tall or long product cannot reach 85% of a square frame without cropping, so this tool judges it against what its shape allows.
Why does my background look white but not pass?
Most off-white backgrounds read 250 to 254, which looks white on screen but is not RGB 255. Camera exposure, warm light and soft shadows all pull a white backdrop down. The tool highlights every background pixel below 255 in orange, so you can see whether it is a shadow you want to keep or background to lift to 255 in your image editor.
Is my image uploaded anywhere?
No. The check runs in your browser using its built-in canvas: the image is read from your device and measured on your machine, and the tool does not upload it. Refreshing the page discards it. Files larger than 2,400 px are measured on a scaled copy, which leaves the ratios being measured unchanged, and the size check uses the file's real dimensions.
What does this tool not check?
It does not read text, logos, watermarks or badges, spot props or accessories you do not sell, or judge whether the image shows your product accurately. It also cannot see the rules for your category or Amazon store, which live in Seller Central. Treat a pass here as three measurements in range, then review the image against your category style guide before uploading.
Need a full listing image set?
Picmato directs the main image to a plain white studio background and plans the rest of the set from your photos or an Amazon, Walmart, Flipkart or Meesho product URL. AI renderers do not guarantee an exact RGB value, so check each export here first.
