Why Optimize Images for E-commerce?

Large images are the #1 killer of Shopify store speed. A slow site means lower conversion rates and poor SEO rankings. Using modern formats like WebP can reduce file size by 30-50% without losing quality.

Best Settings for Platforms

  • Shopify: 2048 x 2048 px (Square), JPEG or WebP.
  • Instagram: 1080 x 1080 px (Square).
  • Amazon: 1000 x 1000 px (Minimum for zoom).
