Resize Images for Shopify
Shopify recommends square product images around 2048 by 2048 pixels so galleries stay consistent and zoom looks sharp. Mixed sizes and ratios make a product grid look uneven, and oversized files slow the store down. Resize every product shot to the same square before you upload.

| Use | Dimensions | Ratio | Notes |
|---|---|---|---|
| Product image (recommended) | 2048 × 2048 px | 1:1 | Square keeps grids even and gives Shopify's zoom enough detail. |
| Product image (maximum) | 4472 × 4472 px | 1:1 | The 20 megapixel ceiling. There is little gain past 2048px. |
| Slideshow / banner | 1600 × 500 px | 3.2:1 | Wide hero images on the storefront. Keep text near the center. |
| Logo | 512 × 512 px | 1:1 | A crisp square logo scales cleanly across the theme. |
How it works

Tips that make a difference
One ratio across the catalog
A single square ratio makes collection pages look designed instead of thrown together.
Compress for Core Web Vitals
Store speed affects both conversions and SEO. Compressing images keeps your theme fast without visible quality loss.
Use transparent PNGs where it helps
For products that sit on colored sections, a transparent cutout blends into any background.
