Product photo guides

Marketplaces reject product photos for reasons they rarely explain at upload. These guides spell out the actual rules for Amazon, eBay, and Etsy — with the exact numbers that matter, why images fail, and how to fix them — from the same people who built the pixel-level checker.

Amazon

• Amazon product image requirements: the complete checklist

  Every rule your main image must pass — pure-white background, 85% fill, 1000px+ for zoom, and the full "not allowed" list.

• Amazon image size & resolution requirements

  1000px vs 1600px vs 10,000px, how zoom actually activates, the DPI myth, and the right dimensions to shoot.

• Why your Amazon white background keeps getting rejected

  Your background looks white but isn't 255,255,255. Why lightbox shots fail, and the two-minute fix.

• How to make a pure white (255,255,255) background

  Get it right in-camera, or rescue photos you already have — without erasing the product's edges.

eBay & Etsy

• eBay photo requirements: the complete guide

  Minimum sizes, the 24 free photos, the stock-image rule, and the condition shots that cut returns.

• Etsy listing photos: the complete guide

  Why the square thumbnail rules everything, 2000px targets, all ten slots, and using video.

• eBay vs Etsy photo requirements: side-by-side

  Size, background, cropping, and watermark rules compared — and how both differ from Amazon.

Fundamentals

• Product photo rejected? A complete diagnostic checklist

  A step-by-step way to find the exact reason any marketplace rejected your image — and fix it.

• JPEG vs PNG vs WebP for marketplace listings

  Which format each marketplace wants, how compression causes silent failures, and how to keep quality.

• How ListingLint checks your photos (methodology)

  Exactly how each check is measured from the pixels, the tolerances we use, and what's exact vs an estimate.
