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.

This means,

  • <link rel="stylesheet" ...> becomes <style>...</style>
  • <img src="image.png"> becomes <img src="data::image/png;base64 ...">
  • <script src="..."> becomes <script>...</script>

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.

  • Maybe use notepad++ to change some text from one string to another, in all the files within a folder. – aparente001 Jul 10 '18 at 16:16
