A joint with a QR code made in Python when sent to Telegram. How to fix?

Question

Python

The task is to create a QR code and send a picture to telegram.
There is such a code, it is working, but with a nuance

import pyqrcode
qr_obj = pyqrcode.create('QR ТЕКСТ')
buffer = BytesIO()
qr_obj.png(buffer)
bot.send_photo(chat_id=some_chat_id, photo=buffer.getvalue())

The nuance is that the QR code is sent very small to Telegram, with a very small extension. Screenshot is attached. I assume that you need to send not a PNG image, but a JPG.
Well, I don't even know why. Help what can be done about this?

Answer 1

have you read the documentation ?

import pyqrcode
qr_obj = pyqrcode.create('QR ТЕКСТ')
buffer = BytesIO()
qr_obj.png(buffer, scale=10)
bot.send_photo(chat_id=some_chat_id, photo=buffer.getvalue())

Answer 2

JPEG is not needed.
Scale the png with PIL (Pillow)
