Flyimg

Effortless image optimization API for your business

About Flyimg

Flyimg resizes, compresses, and converts images in real time through a simple URL-based API, improving site speed and media workflows. It supports JPEG, PNG, AVIF, and WebP with smart fallbacks and efficient global caching, and integrates as drop-in URLs into any backend or frontend. The core image-processing service is open source under the MIT license and can be self-hosted with Docker, while the hosted service offers a free trial for teams that prefer a managed API.
