Django websockets image upload binary get extension

Question

I am trying to send image via javascript websockets as binary data

var ws = new WebSocket('ws://127.0.0.1:8000/ws/message/');

var file = document.getElementById('ImageUpload').files[0];
console.log(file)
ws.binaryType = "blob";
ws.send(file)

Using Django channels I am receiving the binary data

from channels.generic.websocket import WebsocketConsumer

class Consumer(WebsocketConsumer):
    def connect(self):
        .....
        .....
        self.accept()

    def receive(self, text_data=None, bytes_data=None):
        if bytes_data:
            # doing some stuffs

How can get the extension(.jpg/.png) of the image file form the binary data which I receive via websocket, can you pleas guide me some suggestion for this, it will be very helpful for me. Thanks in advance.

you can convert your bytes_data to image by Pillow library in python.take a look at this link: PIL: Convert Bytearray to Image
