Try this   import base64 imgdata   base64 b64decode imgstring  filename    some image jpg     I assume you have a way of picking unique filenames with open filename   wb   as f      f write imgdata    f gets closed when you exit the with statement   Now save the value of filename to your database

You can try using open-cv to save the file since it helps with image type conversions internally  The sample code   import cv2 import numpy as np  def save encoded data  filename       nparr   np fromstring encoded data decode  base64    np uint8      img   cv2 imdecode nparr  cv2 IMREAD ANYCOLOR      return cv2 imwrite filename  img    Then somewhere in your code you can use it like this   save base 64 string   testfile png    save base 64 string   testfile jpg    save base 64 string   testfile bmp

Just use the method  decode  base64   and go to be happy   You need  too  to detect the mimetype extension of the image  as you can save it correctly  in a brief example  you can use the code below for a django view   def receive image req       image filename   req REQUEST  image filename     A field from the Android device     image data   req REQUEST  image data   decode  base64     The data image     handler   open image filename   wb        handler write image data      handler close     And  after this  use the file saved as you want   Simple  Very simple
