Shopify responsive CDN variants and WordPress generated media sizes

Platform Image Guides

Image optimization for Shopify and WordPress.

Every platform processes images differently. Shopify generates its own size variants and serves them through its CDN; WordPress creates a stack of scaled copies on upload and lets plugins handle compression. The guides below cover what each platform does automatically, what it gets wrong, and the settings worth changing — so you stop fighting the defaults and start shipping fast pages.
