Product Image Size & Fill Checker
Drop in your photos and see where they stand against each marketplace spec: the dimensions, a grid overlay, how much of the longest side the product fills, and whether the background is white. It checks, it doesn't resize.
Everything runs in your browser — your photos never leave your device.
What the checks mean
Square 1:1 — most marketplaces expect a square main image.
Resolution — the longest side should meet the platform minimum (Amazon 1600px for zoom, Walmart/Etsy 2000px, Shopify 2048px, eBay 1600px, Google 1000px).
Product fill — the share of the longest side the product occupies. Amazon wants about 85%; the grid and the box on your image show it.
White background — Amazon, Walmart, eBay and Google want a pure white (or clean) background on the main image; Shopify and Etsy are flexible.
How to size product images for each marketplace
Every marketplace publishes its own image rules, and most want a square main image at a minimum resolution on a clean background. Amazon needs the longest side at 1600px (for zoom) with the product filling about 85% of a pure-white frame; Walmart and Etsy lean to 2000px, Shopify to 2048px, eBay to 1600px, and Google Shopping to 1000px on a white or neutral background.
This tool reads each photo's actual dimensions, overlays a grid and a box on the detected product so you can see how much of the longest side it fills, and checks the real numbers against the marketplace you pick. It does not resize or alter your files; it tells you what passes and what to fix.
Pick the marketplace, drop in one or many photos, and read the chips: square, resolution, product fill and (where it matters) white background. Everything runs locally, so your images never leave your device.
Frequently asked questions
Why does my 1024px image fail Amazon?
Amazon needs the longest side at least 1600px to enable zoom; 1024px is below that. The checker compares your image's real dimensions to each platform's minimum, so it flags it honestly instead of assuming a fixed size.
What is 'product fill' and why does it matter?
It's how much of the longest side your product occupies. Amazon's main image should have the product fill about 85% of the frame, not tiny in the middle and not cropped to the edges. The grid and the box on your image show it.
Which marketplaces require a white background?
Amazon, Walmart, eBay and Google Shopping expect a pure white or clean background on the main image. Shopify and Etsy are flexible and allow lifestyle backgrounds, so the checker only flags white where it's required.
Does it resize or change my photos?
No. It only measures and annotates; your files are untouched. If a photo is too small or its background isn't white, fix that at the source. Foca can give you a clean pure-white background.
Are my images uploaded anywhere?
No. All measurement and detection happen in your browser. Your photos never leave your device.
