How do I check if my image meets a marketplace's size rules?

Pick a marketplace from the list, add a product image, and the checker reports its pixel dimensions, aspect ratio, and file size - then marks pass or fail against that marketplace's required dimensions and upload limit.

Which marketplaces are supported?

The checker covers 21 marketplaces, including Amazon, eBay, Walmart, Etsy, Shopify, Zalando, and Trendyol. Each target's dimensions and file-size cap come from that marketplace's published image requirements.

Is my image uploaded to a server?

No. The image is read locally in your browser to measure its width, height, and file size. Nothing is uploaded, stored, or sent anywhere - close the tab and nothing remains.

Where do the size requirements come from?

Every target's dimensions and upload cap are pulled from the same sourced, dated marketplace-rules corpus that powers our compliance checker - not estimates. When a marketplace updates its requirement, the checker updates with it.

What if my image is the wrong size?

The checker tells you the exact target so you can resize or compress to fit. Use the compressor to hit a file-size cap, or re-export at the target dimensions before you upload.
