What is imgproxy?
imgproxy is a self-hosted image processing server engineered to resize and manipulate images dynamically without consuming disk space. Built with developers in mind, it leverages the high-speed libvips library for rapid processing and minimal memory usage, aiming to significantly reduce infrastructure costs associated with image storage and management. By handling image processing on the fly, it eliminates the need for pre-generating multiple image versions, streamlining the development pipeline.
This tool offers a comprehensive suite of features including resizing, smart cropping, advanced compression, rotation, and the application of custom watermarks. It also supports video thumbnail generation, format conversion (such as GIF to MP4), metadata stripping, and various image adjustments like brightness and contrast. Security is a core aspect, with built-in protections against common vulnerabilities like image bombs, alongside features like URL signing and authorization headers to secure image origins and control access.
