How to Decode Base64 Encoded Image String in Python?

Python Code to Decode Base64 Encoded Image String

import base64

original_string = "Hello there visit www.computerscienceai.com"

# Encode

encoded_string = base64.b64encode(original_string.encode('utf-8'))

# Decode

decoded_string = base64.b64decode(encoded_string).decode('utf-8')

print("Encoded string:   ", end="");
print(encoded_string)

print("Decoded string:  ", end= "");
print(decoded_string)



'''
Output:

Encoded string:   b'SGVsbG8gdGhlcmUgdmlzaXQgd3d3LmNvbXB1dGVyc2NpZW5jZWFpLmNvbQ=='
Decoded string:  Hello there visit www.computerscienceai.com

But before decoding image string you need to encode an image to base64 string. You can do that by using the following code.

import base64
 
with open("img.png", "rb") as imageFile:
    imgae_string = base64.b64encode(imageFile.read())
    print(image_string)
