A product-friendly square
Many storefront themes and marketplace templates display listing images in a square around 350 pixels. At that size a product reads clearly while the grid stays light and fast.
It is a 1:1 ratio, so crop square with the item centered and a little even margin around it. Resize to any custom size if your theme asks for something else.

Consistency across a catalog
When every listing image is the same 350x350 square, a grid looks tidy and professional. Mixed sizes make a shop feel sloppy, so normalize the whole set to one dimension.
Shoot or crop products on a clean background so they sit the same way in each square. That uniformity matters more than any single image looking perfect.
Trim weight after resizing
A 350x350 JPEG is small, but a detailed product shot can still run over 100 KB. Compress it to a target size so pages load fast for shoppers.
All of it happens in the browser. Your product photos are processed locally and never uploaded anywhere.
