Convert the Image to base64 and upload the base64 file in S3 and get the same file using django

I need to get a image from django imagefield and convert it to base64 file and upload that converted file in private s3 bucket. And while I getting the image from the s3 bucket I need to get that base64 file and send it to the forntend(reactjs).

Basically I need to convert the image to base64 file, I checked on the internet and Iam not sure where to use that code correctly. Can anyone please suggest me to do that or is any clear documentation available to use as step by step.

Here is my model, views and seriailizers

class Organisation(models.Model):
    """
    Organisation model

I have configure the AWS credentials in the settings file. So kindly please suggest me a way to convert the image file and upload.
