imgproxy v4

What is imgproxy v4?

imgproxy v4 is an open-core image processing server designed for production web applications. Developers run it as a standalone service, point it at original images, and request resized or transformed versions through URL parameters. The product emphasizes speed, security, self-hosting, and operational control over image delivery costs. Version 4 also expands the story around observability, smart cropping, format handling, and Pro image features.

How to use imgproxy v4?

1. 1. Deploy imgproxy with Docker, Linux packages, or a managed infrastructure setup.
2. 2. Store original images in your existing storage or media source.
3. 3. Generate signed imgproxy URLs with resizing, cropping, format, and optimization options.
4. 4. Put a CDN or cache layer in front of imgproxy for production delivery.
5. 5. Monitor errors, transformation costs, and security limits as traffic grows.

Core Features
