Converting any file to binary 1 and 0 and then back to original file without corruption in python

Question

I need a bit help here, don't ask me why it is a wild idea but I want to convert any file into pure binary code 1 and 0 and then back to the original file. The requirement is that when converted the binary code need to be stored in a string data type in a variable and the function that takes in the binary code also accepts the code in a string data type. I would appreciate the solution in python but other languages are also welcome.

I tried to do it but when I converted back to the original file it was always corrupted. I tried to convert it to Hex and then to binary but I was not able to achieve that.

Answer 1

Here's an example Python code that can convert any file to a string of binary code and then back to the original file:

def file_to_binary_string(file_path):
    with open(file_path, 'rb') as file:
        binary_code = file.read()
        binary_string = ''.join(format(byte, '08b') for byte in binary_code)
    return binary_string
def binary_string_to_file(binary_string, file_path):
    with open(file_path, 'wb') as file:
        bytes_list = [int(binary_string[i:i+8], 2) for i in range(0, len(binary_string), 8)]
        bytes_arr = bytearray(bytes_list)
        file.write(bytes_arr)
# Usage example
file_path = 'example.pdf'
binary_string = file_to_binary_string(file_path)
binary_string_to_file(binary_string, 'new_example.pdf')
