Circle CI npm MIT

Import metadata and base64 encoded image content from JPG, PNG, GIF, WEBP and SVG.


$ npm install --save-dev "@redsift/rollup-plugin-imagedata"

Building via ES6 modules

// rollup.config.js
import image from '@redsift/rollup-plugin-imagedata';

export default {
  entry: './index.js',
  dest: 'distribution/my-lib.js',
  plugins: [

Building via require()

// gulpfile.js
var imagedata = require('@redsift/rollup-plugin-imagedata')
gulp.task('task', () => {  
  return rollup({
            plugins: [ 
        .pipe(source('index.js', 'src'))


// use.js
import { width, height, base64 } from './tests/test.png';

console.log(`My image is ${width} pixels wide`);

Note that base64 makes the images 33% larger than the size on disk.

Tree shaking via rollup will ensure large payloads such as the base64 string will be stripped from the bundle if not imported or used by your code.


You may pass a few options to image().

    include: [ ... ], // files to include
    exclude:[ ... ], // files to exclude
    patch: false,   // attempt to fix up non compliant assets e.g. SVG files with no XML headers
    ignoreParsingErrors: true   // Warn but do not fail if files cannot be parsed as images. 
                                // In this case metadata will be missing


This plugin relies on having ImageMagick installed and in the path as this tool is used to extract metadata from the images. If you wish to use WebP, ensure your binary has support for the format. You can verify your binary by inspecting the built in delegates.
