🖼️ Asset image optimization

Shrink the images built into your theme — backgrounds, icons, and banners — so your whole store loads faster.

Who can use this feature?

Asset image optimization is available on the Pro and Expert plans.

What is Asset image optimization?

Your theme has its own set of images: logos, decorative backgrounds, icons, hero banners. These show up on every page, so even a small saving on file size adds up fast.

This feature compresses those theme images automatically.

Why use Asset image optimization?

Speeds up every page — theme images load on every page, so the savings compound across your whole store.
Fully automatic — compresses your theme's images in one pass, no manual selection needed.
Catches what product compression misses — handles logos, icons, banners, and backgrounds that Image compression doesn't touch.
Safe to apply — changes go to a theme you choose, so your live store stays in your control.

📌 Merchant Notes

Product, collection, and blog images are handled separately by Image compression — this feature covers only the images built into your theme.
Theme images appear on every page, so compressing them gives a store-wide speed benefit.
This feature requires the Pro or Expert plan.
