Amazon image size checker

How to use it

Understand the size window

Amazon's technical spec is a window, not a single number: the longest edge of the image must be at least 500 pixels and at most 10,000 pixels. Inside that window, 1000+ pixels turns on the zoom feature that shoppers expect on product pages, and Amazon's own guidance recommends 1000+ for the best experience. If your file sits between 500 and 999 px, the checker marks it WARN: technically uploadable, but you lose zoom. Below 500 px the file cannot be uploaded at all, and Amazon warns against stretching small files to fake the resolution. Export from your camera or design tool at the real source resolution instead.

Practical guide

Size mistakes that hurt listings

• Shipping 500 px images from camera exports. If your editing pipeline downsizes to 500 px to keep files small, you lose zoom. Keep exports at 1000–2000 px on the longest side; Amazon allows up to 10,000 px.
• Ignoring the 10,000 px ceiling. Huge scans or 12K renders can exceed the limit. Most editors can re-export at 2000–4000 px, which is well inside the window.
• Checking size only on the main image. Additional gallery images follow the same 500–10,000 px rule, so a too-small secondary photo can be rejected just like the main one.

The zoom feature is not decorative: when buyers hover or tap a 1000+ px image, Amazon loads a high-resolution version that stays sharp while they inspect the product. Photos under 1000 px lose that capability, and shoppers who cannot zoom often move to a competing listing with a zoomable image. For most product photography, a phone camera already shoots far above the threshold — the usual failure is a downscaled export. Keep your export pipeline at 1500–2500 px on the longest side, which stays inside the 10,000 px ceiling with room to spare, and re-export from the original file rather than from a thumbnail if you need a bigger image later.

One detail worth knowing: the 1000 px zoom threshold applies to how Amazon stores and serves the image, not to how it looks in search thumbnails — thumbnails are tiny either way. What changes with zoom is the buyer's ability to inspect the product closely, which matters most for categories where detail sells: electronics with ports, clothing with fabric texture, jewelry with finish. If your catalog mixes such categories, standardize exports at 2000 px on the longest side and you cover both the 1000 px zoom floor and a margin of safety for future uses like A+ content or sponsored-image crops. Files that size stay inside the 10,000 px ceiling with room to spare, and as JPEG they compress well under the sizes buyers can load quickly on mobile.
