How to Resize a Product Image to 1000×1000 for Amazon
Amazon won't turn on its zoom feature unless your main product image is at least 1000 pixels on the longest side, and zoom is one of the biggest drivers of conversions on a product page. The classic target sellers aim for is a clean 1000×1000square. Here's how to get there with QuickWand's free image compressor and resizer — including an honest note about what “resize to 1000×1000” actually means.
How to resize a product image for Amazon
- Open the Image Compressor and drop your product photo into the drop zone.
- Choose Resize → Max size and enter 1000. This sets the longest side to 1000 pixels and scales the other side proportionally.
- If your photo is already square, the result is exactly 1000×1000. If it isn't square, see the honest note below — you'll need to crop it square first.
- Leave Qualityhigh (90% or so) so the product still looks crisp, and confirm the file is under Amazon's 10 MB limit using the live size estimate.
- Click Download and upload the result to your Amazon listing.
The honest truth about “1000×1000”
QuickWand resizes proportionally. The Max size option fits your image within a maximum dimension on the longest side — it does not stretch or crop it into a square. So if your photo is 4000×3000 (a 4:3 rectangle), setting max size to 1000 gives you 1000×750, not 1000×1000.
To get a true 1000×1000 square, the photo needs to already be squarebefore you resize. If yours isn't, crop it to a 1:1 square first (most phone galleries and photo apps have a square crop tool), then bring the square image into QuickWand and set max size to 1000. Because both sides are now equal, the output lands on exactly 1000×1000.
Amazon's image specs at a glance
- Minimum for zoom: 1000px on the longest side.
- Recommended: 2000px or larger on the longest side for sharper zoom; Amazon even suggests up to 3000px for big screens.
- Maximum: images over 10,000px on the longest side, or over 10 MB, are rejected.
- Main image: a pure white background and the product filling about 85% of the frame.
Given the recommendation, many sellers set max size to 2000rather than 1000 for a higher-quality zoom. If the resulting file is too large, lower the quality slider and watch the live estimate until it's comfortably under 10 MB.
