Fastly Image Optimizer
Fastly Image Optimizer is a cloud-based service that automatically optimizes images on-the-fly as they are delivered through Fastly's content delivery network (CDN). It dynamically resizes, compresses, and converts images to modern formats like WebP or AVIF based on device capabilities and network conditions, without requiring changes to the original source files. This helps reduce bandwidth usage, improve page load times, and enhance user experience by serving appropriately sized and formatted images.
Developers should use Fastly Image Optimizer when building web applications or websites that serve images to a global audience, especially for performance-critical use cases like e-commerce, media sites, or mobile apps. It's particularly valuable for handling responsive images across diverse devices, reducing infrastructure costs by minimizing origin server load, and improving Core Web Vitals scores such as Largest Contentful Paint (LCP). The service integrates seamlessly with Fastly's CDN, making it ideal for teams already using Fastly for edge computing or content delivery.
