Just Responsive Images

Just Responsive Images automates the creation of multiple image sizes from your uploads, delivering the optimal dimensions for each visitor's screen. It works silently in the background, intercepting image requests and serving the most appropriate size based on viewport width and device pixel ratio.

• Automatic size generation: Creates up to 10 predefined image sizes on upload, covering common breakpoints from mobile to desktop.
• On-the-fly resizing: Dynamically resizes images for any missing dimensions without storing duplicates, saving disk space.
• CDN-ready output: Serves images via any standard CDN with full cache control, ensuring fast global delivery.
• Lazy loading included: Adds native lazy loading attributes to images, deferring offscreen images until needed.
• Simple setup: No configuration required for basic use; advanced users can customize breakpoints and quality settings in a single settings page.

By decoupling image handling from your theme or page builder, you get consistent performance improvements without touching template files. The tool is ideal for media-heavy sites like portfolios, e‑commerce stores, and news outlets that need to balance visual quality with fast loading times.
