Bun.Image

Bun.Image is a new chainable image processing API built into the Bun runtime that enables decoding, resizing, rotating, and re-encoding images in multiple formats (JPEG, PNG, WebP, HEIC, AVIF) with zero npm dependencies. The API runs transformations off the JavaScript thread and supports lazy loading from files, S3, or buffers, with features like intelligent JPEG thumbnail generation that avoids materializing full-resolution buffers and multiple resampling filters optimized for different use cases.
