npm install 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 and WebP images of varying dimensions.

Resizing an image is typically 4x-5x faster than using the quickest ImageMagick and GraphicsMagick settings.

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 64-bit OS X, Windows and Linux systems running Node versions 6, 8, 10 and 11 do not require any additional install or runtime dependencies.

Examples

constsharp=require('sharp');

Callback

sharp(inputBuffer).resize(320,240).toFile('output.webp',(err,info)=>{ ... });

Promise

sharp('input.jpg').rotate().resize(200).toBuffer().then(data=>{ ... }).catch(err=>{ ... });

Async/await

constsemiTransparentRedPng=awaitsharp({create: {width: 48,height: 48,channels: 4,background: {r: 255,g: 0,b: 0,alpha: 0.5}}}).png().toBuffer();

Stream

constroundedCorners=Buffer.from('<svg><rect x="0" y="0" width="200" height="200" rx="50" ry="50"/></svg>');constroundedCornerResizer=sharp().resize(200,200).composite([{input: roundedCorners,blend: 'dest-in'}]).png();readableStream.pipe(roundedCornerResizer).pipe(writableStream);

npm install 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 and WebP images of varying dimensions.
Resizing an image is typically 4x-5x faster than using the
quickest ImageMagick and GraphicsMagick settings.
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 64-bit OS X, Windows and Linux systems running
Node versions 6, 8, 10 and 11
do not require any additional install or runtime dependencies.
Examples
constsharp=require('sharp');
Callback
sharp(inputBuffer).resize(320,240).toFile('output.webp',(err,info)=>{ ... });
Promise
sharp('input.jpg').rotate().resize(200).toBuffer().then(data=>{ ... }).catch(err=>{ ... });
Async/await
constsemiTransparentRedPng=awaitsharp({create: {width: 48,height: 48,channels: 4,background: {r: 255,g: 0,b: 0,alpha: 0.5}}}).png().toBuffer();
Stream
constroundedCorners=Buffer.from('<svg><rect x="0" y="0" width="200" height="200" rx="50" ry="50"/></svg>');constroundedCornerResizer=sharp().resize(200,200).composite([{input: roundedCorners,blend: 'dest-in'}]).png();readableStream.pipe(roundedCornerResizer).pipe(writableStream);
