added option preserveExif in v2.0.1 to enabled this feature e.g.,

const options = {
  maxSizeMB: 1,
  maxWidthOrHeight: 1920,
  useWebWorker: true,
  preserveExif: true,
}
try {
  const compressedFile = await imageCompression(imageFile, options);
  console.log('compressedFile instanceof Blob', compressedFile instanceof Blob); // true
  console.log(`compressedFile size ${compressedFile.size / 1024 / 1024} MB`); // smaller than maxSizeMB

  await uploadToServer(compressedFile); // write your own logic
} catch (error) {
  console.log(error);
}
