Can Calibre convert VitalSource Bookshelf books?
VitalSource Bookshelf Mac downloads in vbk format.

Avoid PDF whenever possible. It is a nasty format to make other book formats from (see the sticky in conversion)

Did you actually have success with that tool? It doesn't really work for me...

All that's doing is taking screen shots and creating an image based PDF. Not a good thing to do at all.

Any other alternative?

I suspect that VitalSource ebooks have DRM. Any conversion would require removal of the DRM first. (Except for conversion that exploits the analog hole, like the one linked to above.)

I don't know of any tools that remove DRM from VitalSource ebooks, but that doesn't mean there isn't one.

Is possible but difficult....

The latest version of the converter is here:
https://www.ebook-converter.com/vita...rm-removal.htm

it is stil a script but it is supposed to save in pub format. I have not tried it but it comes with a demo. The problem is that they have a nasty subscription license.

The link mentioned in the previous post is to an app that is not working, and when it worked it used to create screenshots of its page - terrible!
Can you please develop a script to remove the protection of this vitalsource thing? It's really terrible to use as well!

For a drm removal solution to be produced requires:

Someone who wants the drm removed
Someone competent to reverse engineer the DRM and produce a solution

Unless they are the same person, it's unlikely to happen.
