Converting images from URLs to Base64

Just looking for a working service? Head over to imgurl.tools.minzkraut.com


Intro

During the development of my BitBar plugin (ShiftStats), I had to convert quite a lot of icons to base64 strings. Because I've been using Icons8 as my main source for icons it really bothered me to download every icon to then convert them. Those tiny png files started cluttering up my workspace rather quickly and I never used any of them again. Why not delete them? Well... that's a good point, but I have this terrible habit of just downloading those kinds of "temporary files" into whatever path the "save at"-dialog is at that very moment, so they end up not just in the downloads folder, but pretty much everywhere.

So my plan was to make a very simple python script, that can convert any image from a URL into a base64 string.


Requirements

We need python 3.4,requests to get stuff from URLs, base64 to do the conversion as well as sys and io.


The Python script

This time the script is very VERY short. Just 14 lines in total:

import requests, base64, sys  
from io import BytesIO

try:  
    url=sys.argv[1]
except IndexError:  
    url="https://i.stack.imgur.com/r390N.png"

buffered = BytesIO(requests.get(url).content)  
img_base64 = base64.b64encode(buffered.getvalue())  
print(img_base64.decode())  

Going over the lines real quick:
1. - 3. Are our imports, as always. In line 5 to 8 we check whether an argument has been supplied or not. If not, just use a hardcoded URL. I used the standard "broken image" icon broken image

On line 9 we write the stream of the image into our buffer.
On line 10 we convert the bytes from said buffer to Base64.
And finally print it to stdout

We could now go ahead and call out script with a URL as the first argument:

$ python3.4 imgurl2base64.py http://minzkraut.com/content/images/2016/11/logo-m-3.png

And get it in Base64

Thats it.
So simple, yet so handy.
