How to Resize an Image for an Amazon Product Listing (1000px Zoom & 1600px Recommended)
Amazon only turns on its image-zoom feature when your product photo is at least 1000px on the longest side, and it recommends 1600px or larger for crisp, zoomable detail. If your photo is smaller than 1000px, buyers can't zoom in — a proven conversion killer — and if it's oversized or heavy it can be rejected or load slowly. Here's how to resize any product photo to Amazon's exact specs right in your browser, with nothing uploaded to a server.
Step by step
- Open the Resize Image tool at pikdee.com/resize-image and drag in your product photo. All processing happens locally in your browser via canvas — the image never leaves your device, so your unreleased product shots stay private.
- Set the longest side to 1600px. This clears Amazon's 1000px zoom minimum with margin to spare and stays well under the 10000px maximum. Leave 'maintain aspect ratio' switched on so your product isn't stretched or squashed.
- For the main listing image, aim for a square 1:1 frame with the product filling about 85% of it on a pure white (RGB 255,255,255) background — Amazon's requirement for the primary photo. If you need to square it up or trim empty space first, use the Crop Image tool, then resize the result to 1600×1600.
- Click download to save the resized JPG. If the file is more than a few MB, run it through Compress Image to shrink it for faster page loads without visible quality loss, then upload the finished image in Seller Central.
FAQ
What size should Amazon product images be?
At least 1000px on the longest side, which is the minimum for Amazon's zoom feature to activate. Amazon recommends 1600px or larger for the best zoom experience, with a hard maximum of 10000px. A square 1600×1600px image is a safe, high-quality choice for the main listing photo.
Why won't the zoom feature work on my Amazon listing?
Amazon only enables zoom when the longest side of your image is 1000px or more. If zoom isn't working, your photo is too small — resize it to 1600px on the longest side to guarantee zoom turns on.
What format and background does Amazon require for the main image?
JPEG (.jpg) is the preferred format. The main product image must have a pure white background (RGB 255,255,255), show only the product you're selling, and have the product fill roughly 85% of the frame. TIFF, PNG and GIF are also accepted, but JPEG keeps file sizes small.
