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.

World's simplest online Portable Network Graphics image to base64 converter. Just import your PNG image in the editor on the left and you will instantly get a base64-encoded string on the right. Free, quick, and very powerful. Import a PNG – get base64.
data:image/png;base64 tells the browser that the data is inline, is a png image and is in this case base64 encoded. The encoding is needed because png images can contain bytes that are invalid inside a HTML document (or within the HTTP protocol even).
To display that base64 representation in a browser: Browser takes the image/png part and knows that the data following it will be the bytes of a png image. It then sees base64, and knows that the next blob will need to be base64 decoded, before it can then be decoded by its png decoder.
This should do it in Python:
import base64 encoded = base64.b64encode(open("filename.png", "rb").read()) If you love us? You can donate to us via Paypal or buy me a coffee so we can maintain and grow! Thank you!
