# Image zoom

The marketplace feature that magnifies part of a product image on hover or tap. It only works when the image is large enough.

Zoom lets shoppers check fabric, stitching and details before buying. Each marketplace sets its own pixel threshold, and smaller images are shown without it.

Enlarging a small photo to pass the threshold adds pixels but not detail; an AI upscaler reconstructs fine detail instead.

## What marketplaces say about it.
