Why marketplace main images get rejected
Most rejections come from a handful of technical attributes that marketplaces check automatically. Get these right and your image clears the pipeline:
- Background not pure white. Gray, cream, or gradient backdrops are the #1 reject on Amazon, Walmart, and eBay, and are not allowed on Google Shopping.
- Product too small in frame. Amazon’s "fill the frame" rule expects the subject to occupy at least 85% of the image area. A tiny item on a big white field fails.
- Non-square image. A 4:3 or portrait shot breaks the uniform catalog grid that Amazon and Walmart require.
- Resolution too low. Longest side under 500px is rejected almost everywhere; under 1000px loses zoom.
- Text, logo, or watermark in frame. Even a small brand mark can trigger a review. Keep only the product on a clean background.
Our tools measure each attribute and tell you the exact number, so you can fix it before uploading rather than waiting for a suppression notice.

Frequently Asked Questions
What size should a marketplace main image be?
Most marketplaces want at least 500–1000px on the longest side; 1000–2000px enables zoom. Amazon and Walmart expect 1000px+; eBay recommends 1600px; Etsy 2000px on the shortest side; Shopify 2048px; Google Shopping 800px+. Our tools report the exact pixel count and flag anything under the floor.
Do all marketplaces require a white background?
No. Amazon, Walmart, and eBay expect a white or light background; Etsy and Shopify allow lifestyle or colored backgrounds; Google Shopping requires white or transparent. See the comparison table and open each tool for the exact spec.
Are these tools free and private?
Yes. Everything runs in your browser via Canvas and Web Worker. Image bytes never leave your device; we only load our own JavaScript on first use.
Which marketplaces are supported?
Amazon, Walmart, eBay, Etsy, Shopify, and Google — each with its own spec preset (white background, fill, shape, and size rules differ per platform).
Can I process a whole batch of listing images?
Yes. Each tool can batch multiple images and export a ZIP named per marketplace convention — for example Amazon secondary images are named {ASIN}.PT01.jpg … {ASIN}.PT08.jpg, exactly what the inventory template expects.
