You can also use Zotero paired with the Zotero Connector Chrome/Firefox extension for this, I use Zotero as my document archival in addition to my academic citation manager. The Zotero Connector saves any PDF or web page opened in your browser to a local PDF/HTML file, and for HTML under the hood is uses the SingleFile extension to package the whole web page, images and all, into just one file.
It works well - now I'm just looking for a good way to annotate/highlight the local HTML/PDF/ePUB files cross-OS cross-platform. KOReader (https://github.com/koreader/koreader) works pretty well for this with its new hash-based storage option.
