Amazon Listing Photo Sizes: The Rules That Actually Get Enforced (2026)

Amazon's image rules come in two flavors: hard requirements their systems enforce automatically, and recommendations buried in Seller Central that quietly cost you conversions if you ignore them. Sellers using our compressor ask about these constantly, so here's the whole picture in one place — enforcement first.

The numbers, up front

• Minimum for zoom: 1000px on the longest side — below this, the zoom-on-hover feature never activates
• Sweet spot: 1600–2000px on the longest side
• Hard maximum: 10,000px on the longest side, 10MB per file
• Format: JPEG preferred; TIFF, PNG, and GIF are accepted
• Color: sRGB (CMYK is technically accepted but renders unpredictably)

The 1000px zoom threshold is the one to burn into memory. Zoom is how shoppers inspect stitching, texture, and labels before buying, and listings without it convert measurably worse in most categories. There is no warning when you fall below the threshold — the feature just silently doesn't appear.

Main image rules: where listings get suppressed

Your first image (the "MAIN") lives under much stricter, largely automated policing. Break these and the listing can be suppressed from search without a human ever looking at it:

1. Pure white background — RGB (255, 255, 255). Not cream, not light gray, not "basically white". Amazon's detection is automated and unsentimental.
2. The product and nothing else. No text, logos, watermarks, badges, or "Best Seller" ribbons.
3. Product fills at least 85% of the frame. This is also just good practice — most shoppers are on phones, and a product floating in whitespace is invisible at thumbnail size.
4. Only what's in the box. Props and lifestyle staging belong on secondary images.
5. The whole product, uncropped.

Secondary images: nine slots, use them all

Everything forbidden on the main image is allowed — and effective — on the other eight slots. A structure that serves most products well:

• Lifestyle shot: the product in real use, in context
• Infographic: dimensions and key features as callouts — remember it must be readable on a phone at thumbnail size, so make text far bigger than feels natural
• Scale reference: next to a hand or a familiar object; size confusion drives a large share of returns
• Detail close-ups: stitching, ports, material texture — the things zoom exists for
• What's in the box: manage expectations, prevent "missing item" complaints
• Remaining angles: back, side, top

A+ Content dimensions

If you're brand-registered, A+ modules have their own fixed sizes — upload anything else and Amazon's cropper decides what survives:

Preparing files: my recommended export

Amazon recompresses everything you upload anyway, so uploading a 40 MB TIFF gains you nothing except slow uploads and the occasional timeout on flaky hotel Wi-Fi. What I recommend to sellers:

• 1600–2000px on the longest side — comfortably above the zoom threshold, no wasted resolution
• JPEG at quality 85–90 — visually indistinguishable from the original at these sizes
• Under ~1MB per file — bulk uploads of a full catalog go from minutes to seconds
• sRGB, metadata stripped — predictable color, no EXIF surprises

A batch compressor does all four in one pass — that's precisely the workflow InstaShrink's bulk mode was built for, and since it runs in your browser, unreleased product photos never touch anyone's server.
