You can certainly do this with JSZip, since File implements Blob you can probably just do JSZip.loadAsync(yourFileObject).then(zip => { /* do something */ }. See the docs. You'll want to iterate over every file in the archive and create blobs, optimally with Promise.all().

However, for way better performance and smaller size, I would like to point you to my library fflate. If you're trying to get an array of file objects in fflate:

// If you aren't using a bundler, see the CDN instructions in the docs
import { unzipSync, unzip } from 'fflate';

// multithreaded = false is slower and blocks the UI thread if the files
// inside are compressed, but it can be faster if they are not.
const getFiles = async (zipFile, multithreaded = true) => {
  const zipBuffer = new Uint8Array(await zipFile.arrayBuffer());
  const unzipped = multithreaded
    ? await new Promise((resolve, reject) => unzip(
        zipBuffer,
        (err, unzipped) => err
          ? reject(err)
          : resolve(unzipped)
      ))
    : unzipSync(zipBuffer);
  const fileArray = Object.keys(unzipped)
    .filter(filename => unzipped[filename].length > 0)
    .map(filename => new File([unzipped[filename]], filename));
  return fileArray;
}

console.log(someFileObject);
// File { ... }

getFiles(someFileObject).then(console.log)
// [File { ... }, File { ... }, ...]
