>". . .Calibre allows you to convert content from various internet sources

What I find in practice is:

Calibre is very slow and takes a fair amount of work to use in practice.

It converts the input file format to its own internal format, and then to
the designated output file format, and in the process seems to apply a bunch
of heuristics and assumptions which don't seem to work out very well in
practice for me. For example if I send a large set of Unicode code points
into it, a smaller set of Unicode code points comes back out of it -- which
I don't understand. I would have thought that "Unicode is Unicode" and that
Calibre would pass it through unmolested.

It crashes or hangs for me on very big and complicated stuff.

Not to imply that it doesn't work more-or-less on simple stuff, and many
people are using it happily.

(I used Calibre a lot to "check things out" but have decided I can't rely on
it for "checking things out" because it introduces a lot of its own sets of
bugs and assumptions while making file format transformations.)
