Personally, I started building tooling around Data URIs to provide permanent archives to external resources. You can only really store text or single images like this, and you have to get the size below 16KB [1] (64kB at a push) to be reliable. You can do some form of compression, but it would be nicer to have support for longer Data URIs. I've literally embedded these into PDFs and all sorts, all of which still open today. It doesn't really increase the document size notably, but does make them more robust. [1] https://stackoverflow.com/a/695167 https://stackoverflow.com/a/695167
