How it works
Amazon main images are often shown at 1000+ px; uploading near 2000 px on the long side keeps zoom crisp. Etsy recommends up to 2000 px as well.
Use a white or neutral background for marketplace hero images. Square crops (1:1) are common for catalog grids.
Compress to WebP or high-quality JPEG after resize to speed up your product page without visible loss.
Frequently asked questions
What size for Amazon product images?+
Aim for at least 1000 px on the shortest side; 2000 px on the long edge is a safe target for zoom. Check Seller Central for your category’s latest rules.
JPEG or WebP for my shop?+
Marketplaces usually require JPEG or PNG for uploads. Use WebP on your own Shopify or site after export from the same master image.
