Python reads image files base64 encoded in two ways

import io
import base64
from PIL import Image
 
 
def get_picture_base64_data(image_path):
    with open(image_path, 'rb') as img_obj:
        base64_data = base64.b64encode(img_obj.read())
    # try:
    #
    # except Exception as e:
    #     base64_data = ' '
 
    return base64_data
 
 
def decode_base64_str(img_base64_str):
    try:
        decode_str = base64.b64decode(img_base64_str)
    except:
        decode_str = ' '
 
    return decode_str
 
 
def get_picture_base64_data_02(image_path):
    img = Image.open(image_path).convert('RGB')
    output = io.BytesIO()
    img.save(output, format='PNG')
    base64_data = output.getvalue()
 
    return base64_data
 
 
if __name__ == "__main__":
    img_path = "./demo.jpg"
    # img_path = "./502_01.jpg"
    print(decode_base64_str(get_picture_base64_data(img_path))[:100])
    print(get_picture_base64_data_02(img_path)[:100])
