Sharp

Purpose: Sharp is a high-speed Node-API module for converting large images into smaller, web-friendly images.
Image operations: It supports resizing, rotation, extraction, compositing and gamma correction.
Formats: Sharp reads JPEG, PNG, WebP, GIF, AVIF, TIFF and SVG, and outputs JPEG, PNG, WebP, GIF, AVIF, TIFF or raw pixel data.
Runtime support: It works with JavaScript runtimes supporting Node-API v9, including Node.js 20.9.0 or newer, Deno and Bun.
Performance: The maker says resizing is typically 4–5 times faster than the quickest ImageMagick and GraphicsMagick settings, using libvips.
Processing model: Sharp processes small regions of uncompressed image data, uses multiple CPU cores, remains non-blocking, and supports Promises and async/await.
Image input and output: Streams, Buffer objects and the filesystem can be used for input and output, and one input stream can feed multiple processing pipelines.
Image optimization: It can use mozjpeg and pngquant features to optimize JPEG and PNG size, and optimize animated GIF output size.
Security: Sharp treats all input as untrusted and rejects it if decoding produces warnings; input formats can also be restricted at runtime.
Security updates: The latest version published to npm is supported with security updates, and vulnerability reporters can expect a response within 48 hours for a genuine issue.
Supported systems: Prebuilt binaries are provided for macOS, Linux and Windows architectures, with stated architecture and system-library requirements.
Runtime requirement: Installation requires a Node-API v9 compatible runtime, such as Node.js 20.9.0 or newer.
Browser limitation: The optional WebAssembly package does not support use in web browsers or single-threaded environments.
License: The project states it is licensed under Apache License 2.0.
