Collection grids
Serve product cards at the rendered card dimensions instead of larger catalog originals.
shopify image cdn
Test faster Shopify product images without a theme rebuild
Skymage gives Shopify teams a one-page image CDN test: route one repeated product image path through URL-based resizing, WebP or AVIF conversion, and cacheable variants before touching the full catalog.

Shopify image tests should start with repeated surfaces
Collection cards, related products, search results, and product galleries often reuse the same source image at different visual sizes. That makes one image path enough to prove whether an external image CDN test is worth expanding.
Mobile PDP galleries
Give mobile shoppers lighter gallery images without changing the product media workflow.
Campaign landing pages
Reuse Shopify-hosted assets with Skymage URL parameters for seasonal traffic spikes.
one-page rollout
A Shopify-safe validation path
Do not start by changing every product image. Pick one collection or landing page, swap the largest repeated image slots, and compare transferred bytes, LCP, and visual quality.
| Shopify surface | Skymage variant |
|---|---|
| Collection card | ?w=480&h=600&fit=cover&f=webp |
| Mobile product hero | ?w=760&h=920&fit=cover&f=avif |
| Desktop gallery | ?w=1400&fit=contain&q=84 |
| Related product tile | ?w=320&h=400&fit=cover&q=80 |
audit checklist
What the free Shopify image audit checks
Oversized sources
Find product images loading much larger than their rendered dimensions.
Format gaps
Identify where WebP or AVIF variants would reduce transferred bytes.
Repeated paths
Find one product image path repeated enough to make a test meaningful.
Rollout risk
Separate safe URL swaps from changes that require deeper theme work.
free check
Send one Shopify collection or product URL
The audit will return the biggest product image issue, the first Skymage URL to test, and the one-page rollout path that avoids changing the full storefront at once.
