API

Self-hosted server that resizes, crops and converts images on the fly

Price: Free, open source; Pro is paid
Access: None; optional URL signing

About

imgproxy is a standalone HTTP server that resizes, crops, rotates, watermarks and converts images from URL parameters. It runs from a Docker image, supports signed URLs, and is built on libvips. The open-source edition is free; a paid Pro edition adds more features.

What you can do with it

Serve resized and cropped image previews from your own server
Convert source images to WebP or AVIF to cut page weight
Sign image URLs so strangers cannot abuse your processing server

Get started

Run the Docker image on your own server
Request an image through a processing URL
Configure a key and salt to sign URLs in production

Example

docker run -p 8080:8080 -it ghcr.io/imgproxy/imgproxy:latest
# Unsigned test URL (only while no key/salt pair is configured):
# http://localhost:8080/insecure/rs:fill:300:200/plain/https://example.com/image.jpg
