What imgproxy is
imgproxy is a self-hosted HTTP server that transforms images on demand from a source URL and processing options. It can resize, crop, trim, rotate, pad, watermark, apply filters and color adjustments, and chain processing steps. Sources include HTTP(S), local files, Amazon S3-compatible storage, Google Cloud Storage, Azure Blob Storage, and OpenStack Swift. Supported formats include JPEG, PNG, WebP, AVIF, JPEG XL, GIF, SVG, ICO, HEIC, BMP, TIFF, and animated GIF and WebP. Optimization options include stripping metadata and ICC profiles, PNG quantization, and serving WebP, AVIF, or JPEG XL when a browser supports them. It can run in Docker or Kubernetes with Helm, on cloud platforms, or on a local machine. Security controls include signed URLs, authorization headers, restrictions on sources and file sizes, dimension checks, URL expiration, and SVG sanitization. The open-source version is MIT-licensed.
