imagor is a fast, secure image processing server and Go library built on libvips, exposing on-the-fly image transformations via a thumbor-compatible URL syntax. It ships with first-class Docker support and streaming-based parallel processing for high-throughput thumbnail generation.

Use cases

• resize and crop images on the fly via URL
• generate web-optimized thumbnails for a website
• convert images to webp or avif automatically
• add watermarks to images served over HTTP
• replace thumbor with a faster drop-in image server
• serve animated gif crops and transformations
• self-host an image processing service behind a CDN

When to choose

• you need a high-performance, self-hosted image transformation server
• you want a thumbor-compatible drop-in replacement with better speed
• you need Docker-first deployment with S3/storage loader support
• you want a Go library for libvips-based image processing

When to avoid

• you only need simple one-off local image edits in a GUI
• your stack requires a managed SaaS image API
• you need heavy video processing beyond thumbnails (see imagorvideo instead)
