I have some HTML files which need few external files such as CSS, PNG etc. Instead of linking to those external files, I'd like to make the HTML files self-contained.
<link rel="stylesheet" ...>becomes
<img src="data::image/png;base64 ...">
Ideally, it supports other stuff that I can't think of at the moment.
I'm looking for such a tool on Windows. It must work offline and be gratis.
