How to Compress Images for Shopify
Shopify stores depend on clean product images, but large files can slow pages down and make theme sections feel heavy. This guide focuses on getting images smaller before upload.
Example input
A batch of product photos exported too large from a camera or design tool.
Expected output
Smaller, store-ready images that preserve enough quality for ecommerce display.
Step by step

Compress each product image before upload, starting with moderate settings instead of maximum compression.
Resize oversized images so the final dimensions match real storefront usage more closely.
Keep transparency only where the product design actually needs it.
Review the optimized files on a mobile-width preview before final upload.

FAQ
Questions people still ask after reading
Should all Shopify product photos be JPG?
Not always. JPG is often the better default for photos, but PNG still matters for transparency-heavy assets.
Is resizing just as important as compression?
Yes. Oversized dimensions are a common reason ecommerce images stay heavier than they need to be.
