Some PDFs I extracted using pdf2htmlex contained graphics, and therefore pdf2htmlex returned them as base64 encoded images in img elements in HTML. Here’s a small snippet of what it returned

<img class="bi x0 y0 w1 h1" alt="" src="data:image/png;base64 (rest of base64 data)

However, upon trying to decode the base64 image data, the console returned the error

line 87, in b64decode
return binascii.a2b_base64(s)
binascii.Error: Incorrect padding

indicating that there were not enough ‘=’ signs for this to be a base64 string and that there were meant to be more.

Here is the code I tried decoding the string with

import base64
from io import BytesIO
from PIL import Image

base64_string = '[base64 string]'

img_data = base64.b64decode(base64_string)

img_bytes_io = BytesIO(img_data)

img_pil = Image.open(img_bytes_io)

img_pil.show()

However, it simply returned insufficient padding. After receiving the padding error, I decided to implement the following

import base64
from io import BytesIO
from PIL import Image

base64_string = '[base64 string]'

while len(base64_string) % 4 != 0:
    base64_string += "="

img_data = base64.b64decode(base64_string)

img_bytes_io = BytesIO(img_data)

img_pil = Image.open(img_bytes_io)

img_pil.show()

The while statement making sure there is enough padding

However, I still encountered the error

line 3309, in open
    raise UnidentifiedImageError(msg)
PIL.UnidentifiedImageError: cannot identify image file <_io.BytesIO object at 0x000001EDFAD711C0>

This suggests that the image is corrupted or unidentifiable. However, I am able to open the base64 encoded image as an image on HTML files and on Chrome with no problem.

Here’s an example of a base64 string I received from pdf2htmlex

I’m not very familiar with base64 encoding and the PIL library, so I’m not sure if there is an issue in the above code or in the base64 encoded string.
