About Sharp
By Toolradar Team·
Sharp is a high-speed Node-API module designed for efficient image processing. Its primary use case involves converting large images in common formats (like JPEG, PNG, WebP, GIF, AVIF, TIFF, SVG) into smaller, web-optimized versions with varying dimensions. It's built upon the blazingly fast libvips library, making it significantly quicker than alternatives like ImageMagick or GraphicsMagick for resizing operations.
This module is ideal for developers working with Node.js, Deno, or Bun who need to handle image transformations programmatically, especially for web applications where performance and optimized file sizes are crucial. It supports a wide range of operations beyond just resizing, including rotation, extraction, compositing, and gamma correction, while correctly handling color spaces, embedded ICC profiles, and alpha transparency. Sharp ensures quality through Lanczos resampling and offers features for optimizing output file sizes without requiring separate tools.
