Amazon Product Image Resizer

The number that matters is the zoom threshold

Amazon turns on its hover to zoom feature once the longest side of an image reaches 1,000 pixels. Below that, the image still displays but shoppers cannot inspect it, and zoom is what they use to check texture, materials, labels, and detail before buying. Meeting the minimum is not the goal though. At exactly 1,000 pixels zoom activates but the zoomed view is soft, while at 2,000 it is crisp on a high density display. Since the file still sits well under the 10 MB cap either way, there is no reason to upload the bare minimum. Treat 1,000 as the floor and 2,000 as the target.

ImageDimensions: Amazon product image requirements, 2026

The background is checked by a machine, not a person

The pure white requirement is enforced automatically, and it is stricter than it sounds. Amazon detects off white, grey, or textured backgrounds and either rejects the image or suppresses the listing, so a background that looks white to the eye is a common cause of a listing going quiet. The specific failure is a background measuring around 250, 250, 250 instead of 255, 255, 255, or a white sweep carrying soft grey shadows around the product. Shooting on a white sweep is a start, but most sellers still have to correct the background in editing, and checking the corner pixels of the exported file is the quickest verification.

• Off white or grey backgrounds are detected and rejected automatically.
• A background measuring about 250,250,250 trips the check. It must be 255,255,255.
• Soft grey shadows around the product also fail, even on a white sweep.
• Check the corner pixels of the exported file before uploading.
• A rejected main image can suppress the listing, not just drop the image.

NoteA background that looks white but measures 250,250,250 is the most common rejection cause.

The main image is product only, and the extra ones are not

The main image carries strict rules: no text, no logos, no watermarks, no borders, and no props. Only the product itself. The additional images are where the relaxed rules apply, and they are where a listing actually sells. A listing supports up to nine images in total, with the main image plus up to eight more, and on those you can show alternate angles, an infographic with measurements, a lifestyle shot in context, feature callouts, and comparisons. A poor habit is putting a "best seller" badge on the main image, which violates the product only rule; that content belongs on an additional image.

NoteThe main image is product only. Text, badges, and infographics belong on the additional images.

Amazon does not fix your file for you

This is the difference that catches people out when they move from a website to a marketplace. A CMS or a social platform will re-encode and resize an upload for you. Amazon does not. The file you upload is very close to what the shopper sees, so preparing the source correctly is the whole job. That means a non square photo gets padded or cropped inside Amazon frame rather than adapted by you, which is why exporting at 1:1 is the correct move, and why a 9,000 pixel 15 MB TIFF simply fails the file cap when a 2,000 pixel JPEG of the same product would look identical and be accepted.

• Amazon does not resize or recompress your upload the way a CMS does.
• The file you upload is close to what shoppers see.
• A non square photo is padded or cropped inside Amazon frame.
• Export at 1:1 rather than letting Amazon crop.
• A huge TIFF can fail the 10 MB cap where a 2,000 px JPEG looks identical.

NoteUnlike a website, Amazon shows very close to your uploaded file. Prepare it properly.
