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
