Convert Image To String and Vice Versus

sometime we need to convert image to string to fully save the data into one file, then it comes base64 module.

Base64 enables to convert bytes which in the format binary or text data to ASCII characters.

it is in base of 64 characters;

• 26 uppercase letters
• 26 lowercase letters
• 10 numbers
• '+' and ‘/' for new lines

thus each character in base64 represents 6 (2^6=64) bits of info in binary.

command line

official line: https://docs.python.org/3.8/library/base64.html

import base64

base64.b64encode(s, altchars=None)

to write it to a text file

import base64

with open('image.jpg', 'rb') as f:
    data = f.read()
# encode to base64
data_encode = base64.b64encode(data)

# write binary
with open('file.txt','wb') as f:
    f.write(data_encode)
