node-webp-bin

WebP 0.3.0 Node.js wrapper that makes it seamlessly available as a local dependency on OS X, Linux and Windows.

WebP is a new image format that provides lossless and lossy compression for images on the web. WebP lossless images are 26% smaller in size compared to PNGs. WebP lossy images are 25-34% smaller in size compared to JPEG images at equivalent SSIM index. WebP supports lossless transparency (also known as alpha channel) with just 22% additional bytes. Transparency is also supported with lossy compression and typically provides 3x smaller file sizes compared to PNG when lossy compression is acceptable for the red/green/blue color channels.

var execFile = require('child_process').execFile;
var webpPath = require('optipng-bin').path;
 
execFile(webpPath, ['-h'], function(errstdoutstderr) {
    console.log(stdout);
});

You can also run it directly from ./node_modules/.bin/webp-bin
