webpconv-es6

A small node.js library for working with WebP format. Supports the Promise API.

Example

Convert .png image to .webp and save

const converter = require('webpconverter');
const fs = require('fs');

let options = '-q 80';
converter.cwebp('path/to/image.png', options, 'path/to/output.webp')
    .then((res) => {
        console.log(res) // 'path/to/output.webp'
    }).catch((err) => {
        throw new Error(err);
    });

Convert .png image to .webp without saving

const converter = require('webpconverter');
const fs = require('fs');

let options = '-q 80';
converter.cwebp('path/to/image.png', options)
    .then((res) => {
        // Do something with data
        fs.writeFile(path.join(__dirname, 'path/to/output.webp'), res, 'hex');
    }).catch((err) => {
        throw new Error(err);
    });

Convert .webp image to .png format without saving

const converter = require('webpconverter');
const fs = require('fs');

return converter.dwebp('path/to/image.webp')
    .then((res) => {
        // Do something with data
        fse.writeFile(path.join(__dirname, 'path/to/output.png'), res, 'hex');
    }).catch((err) => {
        throw new Error(err);
    });
