heic-decode

Decode HEIC images to extract raw pixel data.

Install

npm install heic-decode

Usage

const fs = require('fs');
const decode = require('heic-decode');

(async () => {
  const buffer = await promisify(fs.readFile)('/path/to/my/image.heic');
  const {
    width,  // integer width of the image
    height, // integer height of the image
    data    // ArrayBuffer containing decoded raw image data
  } = await decode({ buffer });
})();

You can use this data to integrate with other imaging libraries for processing.

Note that while the decoder returns a Promise, it does the majority of the work synchronously, so you should consider using a worker thread in order to not block the main thread in highly concurrent production environments.
