imgproxy

imgproxy is a specialized image processing server. You install it on your own infrastructure, and it handles tasks like resizing, cropping, format conversion, and watermarking in real time. Instead of preparing dozens of image variants upfront, you request the exact version you need by adding parameters to a URL. The server fetches the original from your storage, processes it, and delivers the result. This approach simplifies your image pipeline and ensures users always get an optimally sized file.

The tool is built for speed and security. It checks for potential threats like oversized 'image bombs' and uses URL signing to prevent denial-of-service attacks. It supports modern formats like WebP and AVIF for better compression. The core product is open source, while a paid Pro version adds advanced features. These include AI-driven object detection for smarter cropping, automatic quality adjustment, and preview generation for videos and PDFs.

imgproxy is a strong fit for development teams managing large-scale image delivery. E-commerce sites use it to serve perfectly sized product photos. Media companies and social platforms rely on it to generate thumbnails and optimized versions of user content. By running on your own servers, it cuts costs compared to third-party SaaS services and keeps your image data within your infrastructure.
