How do you base-64 encode a PNG image for use in a data-uri in a CSS file?

I want to base-64 encode a PNG file, to include it in a data:url in my stylesheet. How can I do that? I’m on a Mac, so something on the Unix command line would work great. A Python-based solution would also be grand.
This should do it in Python: import base64 binary_fc = open(filepath, 'rb').read() # fc aka file_content base64_utf8_str = base64.b64encode(binary_fc).decode('utf-8') ext = filepath.split('.')[-1] dataurl = f'data:image/{ext};base64,{base64_utf8_str}' Thanks to @cnst comment, we need the prefix data:image/{ext};base64, Thanks to @ramazanpolat answer, we need the decode('utf-8')
