CEO of Crocodoc here. Crocodoc's API will remain a stand-alone offering as part of the Box platform, and we're going to be investing heavily in making our service even better! Nothing's going away, and we'll continue to support all of our existing (and new) customers.
Is this agreed on, and properly documented? Or is it just your words against Box that very soon will become your owner and can do whatever the hell they want to, including shutting you down (if some insane people are in charge [this happened before]).
It is indeed. I believe that their API will remain up and be used by many, but it probably won't be used by DropBox for long. Classy move by their CEO to make it clear that DropBox is welcome to use it.
This is going to sound like I'm trolling you, but pdf.js only supports PDFs. You'll need to convert those other doc types to PDFs before using them with pdf.js.
You can try MS office. If you dont want to buy/install it you can just use the in browser version. All you need is a MS account and you can also export the files as pdf..
It's a shame, since Crocodoc seemed way better than anything else out there for doing HTML5 previews.
