About

Fastly Image Optimizer automates image processing and delivery for image-heavy sites and applications. It transforms images at the edge in response to request parameters, allowing teams to request variants without pre-generating and storing each one. Options include resizing, quality adjustment, cropping or trimming, orientation changes, format conversion, caching, and delivery. Supported formats are WebP, AVIF, JPEG, and PNG. Developers control processing through query parameters and configuration, and can retain existing image sources while integrating with asset pipelines and CMS platforms. The service can be enabled in the Fastly control panel or through the API; Compute SDK access is available through a beta program. Optimized images are cached for reuse. A free plan covers 100,000 image requests per month. Listed paid rates are billed per 10,000 requests and vary by monthly volume tier. Every request, including one sent through the SDK, counts as a billable image request.

Who it is for

It suits teams operating image-heavy media sites, ecommerce platforms, and SaaS applications that want edge image processing. Developers can control transformations through request parameters and configuration and connect the service to current image pipelines.
