A Dart library to encode and decode various image formats.

The library has no reliance on dart:io, so it can be used for both server and web applications.

The image library currently supports decoding and encoding the following formats:

  • PNG / Animated APNG
  • JPG
  • TGA
  • GIF / Animated GIF

Decoding Only:

  • WebP / Animated WebP



Load a WebP image, resize it, and save it as a png:

import 'dart:io' as Io;
import 'package:image/image.dart';
void main() {
  // Read a webp image from file.
  Image image = decodeWebP(new Io.File('test.webp').readAsBytesSync());

  // Resize the image to a 120x? thumbnail (maintaining the aspect ratio).
  Image thumbnail = copyResize(image, 120);

  // Save the thumbnail as a PNG.
  new Io.File('thumbnail.png')



The image library aims to provide server-side programs the ability to load, manipulate, and save various image file formats.
