URL-Based Processing

Instead of processing images ahead of time, imgproxy generates images on-the-fly based on URL parameters:

https://imgproxy.example.com/
  /insecure/
  /resize:fill:800:600/
  /plain/https://example.com/image.jpg

Security Features

imgproxy supports URL signing to prevent abuse, source URL whitelisting, and runs in a sandboxed environment for security.

CDN Integration

Works seamlessly with CDNs. The CDN caches processed images, so imgproxy only processes each variant once.

ImageMagick Approach

Typically integrated into your application. You process images during upload or on-demand, store multiple versions, and serve them statically.

# Pre-process during upload
convert original.jpg -resize 800x600 thumb.jpg
# Serve static file
https://cdn.example.com/thumb.jpg

imgproxy Approach

Deploy as a microservice. Store only original images, generate variants on-the-fly, and let the CDN handle caching.

# Store only original
https://storage.example.com/original.jpg
# Generate on-the-fly via imgproxy
https://imgproxy.example.com/.../original.jpg

Processing Speed

imgproxy is built on libvips and is significantly faster than ImageMagick. It can handle hundreds of requests per second on modest hardware.

Storage Efficiency

With imgproxy, you only store original images. ImageMagick workflows often require storing multiple pre-processed versions, consuming more storage.

Deployment Simplicity

imgproxy is distributed as a single Docker container, making it easy to deploy and scale horizontally behind a load balancer.

Choose imgproxy If:

• You need dynamic image resizing for web delivery
• You want to minimize storage costs
• You're building a high-traffic application
• You need CDN integration
• You want simple horizontal scaling
• Security and isolation are important

Choose ImageMagick If:

• You need complex image effects and transformations
• You're doing batch processing or automation
• You need to integrate processing into your application
• You require extensive format support
• Command-line tools fit your workflow better
