## What it is
bimg is a small, fast Go library for high-level image processing built on the libvips C library via bindings. It supports operations like resize, crop, rotate, zoom, watermark, blur, and format conversion (JPEG, PNG, WEBP, and optionally TIFF, PDF, GIF, SVG, AVIF) with a low memory footprint and performance typically several times faster than ImageMagick or Go's native image package.

## Use cases
- resize and crop images in a Go service
- generate thumbnails for uploaded photos
- add text or image watermarks to images
- convert images between JPEG, PNG, and WEBP
- auto-rotate images based on EXIF orientation
- apply gaussian blur or grayscale effects to images
- process large batches of images quickly with low memory

## When to choose
- you need fast, memory-efficient image processing in Go
- you want a simple programmatic API over libvips
- you need format conversion including WEBP and AVIF
- throughput matters more than ImageMagick-based alternatives

## When to avoid
- you need an HTTP-based image processing API (use imaginary instead)
- you cannot install libvips and a C compiler in your environment
- you need advanced editing features beyond bimg's supported operations
- you want a pure-Go solution with no C dependencies
