Summary

Fastly Image Optimizer automates image processing and delivery for image-heavy sites and apps. It can resize, crop or trim, adjust quality and orientation, convert formats, cache, and deliver images on demand at the edge. Transformations are generated in real time from request parameters, so teams can request variants without pre-generating and storing each one. Optimized images are cached for reuse on later requests. Supported formats include WebP, AVIF, JPEG, and PNG, with developers setting resizing, quality, format, and cropping through query parameters and configuration. The service works with existing asset pipelines and CMS platforms while teams retain their current image sources. It can be enabled in the Fastly control panel or through the API; Compute SDK access is available through a beta program. The free plan covers 100,000 image requests per month. Paid rates are billed per 10,000 requests, with listed tiers from 0.50 USD per month for 100,000–10 million requests to 0.01 USD per month beyond 5 billion. Each request sent to Image Optimizer, including through the SDK, counts as billable.
