## What it is
imgproxy is a fast, secure standalone HTTP server written in Go (built on libvips) that resizes, processes, converts, and optimizes images on the fly via specially crafted URLs. It acts as a drop-in replacement for in-app image processing code and is distributed primarily as Docker images and Linux packages.

## Use cases
- resize images on the fly via url parameters
- self-hosted image processing server to replace cloud image services
- generate thumbnails and responsive image variants for a website
- convert images to webp avif or jpeg xl automatically
- crop rotate and watermark images through an http api
- optimize image delivery and reduce bandwidth costs
- replace imagemagick code in a web application with a dedicated microservice

## When to choose
- you serve many user-facing images and want fast on-demand resizing without pre-generating variants
- you want to offload image processing from your app into a dedicated, scalable microservice
- you want self-hosted image processing to avoid SaaS image-resizing bills and third-party data sharing
- you need modern format support (WebP, AVIF, JPEG XL) with automatic format negotiation

## When to avoid
- you only need occasional one-off image conversions in a script rather than a running service
- you need advanced features like video/PDF previews, object detection, or SSIM auto-quality that require the paid Pro version
- you cannot run additional server infrastructure or containers alongside your application
