Convert html images to inline base64

Question

I'd like to automatically convert html files with png images to inline base64 images included in single html file. Is there any such ready-to-use tool?

Here is simple python script which I used recently... It act as a filter:

#!/usr/bin/env python
# -*- coding:utf-8 -*-

import fileinput
import re
import base64
import mimetypes
import os


def replacement(match):

    fn = match.groups()[0]

    if os.path.isfile(fn):
        return 'src="data:%s;base64,%s"' % (mimetypes.guess_type(fn)[0], base64.b64encode(open(fn, 'rb').read()))

    return match.group()



def main():

    fi = fileinput.FileInput(openhook=fileinput.hook_encoded("utf8"))

    while True:
        line = fi.readline()
        if not line:
            break
        print re.sub(r'src="(.*?)"', replacement, line).encode('utf-8'),



if __name__ == '__main__':
    main()
