Quick and Fast Image Processing Module in Node.js

Sharp is an image processing module which uses the libvips library to provide fast processing for Node.js projects.

Sharp is a fast processing image module for Node.js projects that is powered by libvips image processing library. Due to this addition, Sharp like the name suggests, has a high speed processing power as it only stores a few regions of the uncompressed image data in the memory freeing up much of the used CPU power and L1/L2/L3 cache

The library also makes sure that no child processes are spawned and async or await processes are supported. As an open source image processing module, Sharp supports multiple image formats and uncompressed raw pixel data as well. For optimal performance make sure you are using Node.js version 10 and above.

Resize Images via Free JavaScript API

The open source sharp library allows JavaScript developers to resize images programmatically. Sharp allows you to convert large image formats into smaller sizes that are compatible with different web applications. With the help of the libvips library Sharp has a 4 to 5 times faster image processing speed as compared to other image format converters such as ImageMagick or GraphicsMagick. Sharp ensures that the image quality isn’t compromised by Lanczos resampling module.

Image Processing via Free JavaScript API

The sharp library enables software developers to process image in JavaScript framework. You can perform image operations such as image resizing, rotating, extracting, corrections and compositing. Sharp is compatible with MacOS, Windows and Linux systems and doesn’t require any additional installations when using the Node.js Version 10 and above
