README
sharp
The typical use case for this high speed Node.js module is to convert large images in common formats to smaller, web-friendly JPEG, PNG, WebP, GIF and AVIF images of varying dimensions.
Resizing an image is typically 4x-5x faster than using the quickest ImageMagick and GraphicsMagick settings due to its use of libvips.
Colour spaces, embedded ICC profiles and alpha transparency channels are all handled correctly. Lanczos resampling ensures quality is not sacrificed for speed.
As well as image resizing, operations such as rotation, extraction, compositing and gamma correction are available.
Most modern macOS, Windows and Linux systems running Node.js >= 14.15.0 do not require any additional install or runtime dependencies.
