Enhanced performance for an enhanced user experience

Fastly's Image Optimizer lets you improve performance without sacrificing user experience. Enhance image-heavy sites' page load speeds with optimized images, transformed at the edge.

Transform and serve images faster

Offload image transformation to our powerful edge cloud platform. When an image is requested, we resize it, adjust quality, crop/trim, change orientations, convert formats, and more, all on demand. This eliminates latency and allows you to improve page load times, bolstering your site’s SEO performance.

Cut infrastructure costs

With Image Optimizer, you can reduce costs and improve productivity. Eliminate expensive image transformation applications and servers at your origin. Save on storage costs by storing one source file and generating the optimal image for each profile on demand, at the edge. Lower egress costs by caching more at the edge.

Delight your users — and team

Image Optimizer can help delight your site’s visitors with fast-loading pages — and let your dev team focus on more fulfilling work than optimizing images. You could save time like one customer, who said we optimized their entire image library for mobile in about a week — a project that would have otherwise taken six months to complete.
