Before uploading. Shopify applies its own compression after upload, but pre-compressing gives you control over the output quality and file size. This ensures your images look exactly as intended in your storefront.
Shopify recommends uploading square images at 2048x2048px for product photos. Keeping file sizes under 500KB ensures fast storefront load times and better Core Web Vitals scores, which can affect your store's SEO performance.

Page speed is one of Google's ranking signals, and images are typically the largest contributor to slow load times. A Shopify store with uncompressed product photos can take 4-6 seconds to load on mobile, long enough for many shoppers to leave before seeing your products.
Google's Core Web Vitals measure Largest Contentful Paint (LCP), which is often triggered by a hero image or first product photo. Keeping your images under 500KB and properly sized means faster LCP scores, better search visibility, and higher conversion rates.
Shopify automatically applies some compression when you upload images, but the results can be unpredictable. Pre-compressing your images before uploading gives you full control over quality and file size, so your product photos look sharp and load fast on every device.
JPG is the safest choice for product photos. It is universally supported, produces small file sizes at high quality settings, and works reliably across all browsers and Shopify themes.
WebP produces files roughly 25-35% smaller than JPG at the same visual quality. All modern browsers support WebP, and Shopify's CDN handles it well. If storefront speed is a priority, WebP is the better option for product images.
PNG should only be used for images that require a transparent background, such as logos, icons, or overlay graphics. For product photos, PNG files are unnecessarily large.
