Welcome folks today in this blog post we will be looking on how to encode a pdf file to base 64 string in python 3 using the core base64 module. All the source code of the application is shown below

Get Started

In order to get started you need to install base64 module of python using the pip command as shown below

pip install base64

After installing this module just make an app.py file and copy paste the following code

app.py

import base64

with open("sample2.pdf", "rb") as pdf_file:
    encoded_string = base64.b64encode(pdf_file.read())
    print(encoded_string)

Here in this block of python code as you can see in the first line we are importing base64 module and after that we are opening the local pdf file with the path and then after reading it we are converting or encoding to base64 using the b64encode method which is available in the base64 module. Lastly we are printing the output encoded base64 string to the console

Now if you execute the python script by typing the below command in the console

python app.py

As you can see the following base64 code of the input pdf file is printed out
