Amazon product images must be at least 1000 pixels on the longest side, in JPEG format, with a pure white background (RGB 255, 255, 255) for the main image. The product must fill at least 85% of the image frame. For zoom — which measurably increases conversion — you need at least 1600 pixels on the longest side. The recommended upload size is 2000 pixels.

The 1600px zoom threshold is the real conversion lever
Amazon's zoom feature activates only when the image is at least 1600 pixels on the longest side. When a customer hovers over a product image on desktop, zoom shows a magnified inset. Studies of Amazon listing performance consistently show that listings with active zoom have higher conversion rates — buyers want to inspect detail before purchasing.
The minimum (1000px) gets your listing live. The zoom threshold (1600px) is where you start competing properly. At 2000px you have margin for slight cropping adjustments without dropping below zoom threshold. Uploading above 2000px provides no meaningful benefit since Amazon's zoom window is capped regardless of source resolution.
If your current product photos are 1000–1500px, prepare a 2MB version at 2000px and re-upload. The zoom activation alone can noticeably improve conversion.
Why "white background" means exactly RGB 255,255,255
This trips up a significant number of sellers. Off-white walls, light grey studio backdrops, and cream paper all look white to the eye but register as colour in a photograph. Amazon's automated image checker measures the background and flags anything that isn't pure 255,255,255.
The result is listing suppression — your product disappears from search results without any error message telling you why. Suppressed listings appear in Seller Central's Fix Your Products report.
Two reliable approaches: shoot on a proper white sweep (a thick white paper roll or white acrylic), or use photo editing to replace the background with pure white after shooting. If you're doing the latter, the background must be uniformly 255,255,255 with no gradient from the editing — even a slight feathering at the edges registers as non-white.
The 85% frame fill rule and how it gets broken
Amazon requires the product to occupy at least 85% of the image frame. Small products photographed at a distance, or large white margins left for "breathing room" around the product, fail this requirement.
This rule also catches a common mistake with small products: photographing a ring, earring, or small accessory against a white surface, leaving large expanses of white around it. The product might be 30% of the frame. Amazon wants it cropped tight — 85% means the product nearly fills edge-to-edge.
The practical approach: crop your image so the product nearly fills the frame, then add a small consistent white margin (5–10% on each side). This hits the 85% threshold while keeping the presentation clean.
Secondary images: where you have full creative freedom
The white background rule only applies to the MAIN image (position 1 in the image carousel). Secondary images (ALT images, positions 2–9) can use any background, props, lifestyle context, or infographic overlays. This is where you show the product in use, demonstrate scale, highlight key features with text callouts, and build the case for purchase.
Secondary images still need to meet the size minimums (1000px, preferably 2000px) and the file format requirements. They can't show content that isn't in the listing (unrelated products, accessories sold separately without disclosure) or make health/medical claims that violate Amazon's guidelines.
Preparing images for Amazon upload
- Shoot or source at high resolution. 2000px on the longest side minimum. For a square product shot, 2000×2000.
- Replace or confirm the background. Use Photoshop, GIMP, or a background removal service. Verify the background is RGB 255,255,255, not close-but-not-quite white.
- Check frame fill. The product should occupy at least 85% of the image area.
- Export as JPEG. Quality 85–95%. A 2000×2000 JPEG at 90% quality typically lands at 500KB–1.5MB — compress to under 2MB for fast uploads without hitting Amazon's 10MB limit.
- Name the file. Amazon accepts any filename but using the ASIN in the name helps track which image corresponds to which listing when managing a large catalog.
