PDF to HTML conversion
So I don't forget it again: Adobe PDF conversion by e-mail
Submit links or PDFs as attachments via e-mail or web.
However, there's an even better service, web-only right now but it seems they'll bring back their e-mail conversion. GoBCL converts from PDF to a bunch of different formats such as HTML, TXT, RTF, etc. for free, personal use. PDF size limit of 2MB.
Update: free conversion to and from PDF and HTML. Gotta buy the software/service for the other formats.
