Amazon Image Resizer

Amazon requires product images to be at least 2000 pixels on the longest side to enable the zoom feature, and listings without zoom convert measurably worse. The main image has stricter rules still: pure white background (RGB 255, 255, 255), no text, no logos, no extra objects. Images that break the rules can be suppressed, which means your listing effectively disappears.

This resizer scales your photo to fit within 2000 pixels on the longest side while preserving the aspect ratio. Prepare your main image on a white background before resizing, then export as JPG at quality 90 or above for the cleanest result. A centered square crop mode is available for sellers who want the product to dominate the frame.

Amazon's own guidance says the product should fill at least 85 percent of the image frame, and that is the detail most sellers miss. A compliant but tiny product floating in white space looks unprofessional next to competitors whose products fill the frame. After the main image, Amazon allows six or more additional images: use them for lifestyle shots, scale references, infographics and close-ups of details.

All processing is local to your browser. Supplier photos and unreleased products stay private, which matters when you are prepping a launch.
