You could use zargs for that:

autoload -Uz zargs # in ~/.zshrc

zargs -I@ ./* -- ebook-convert @ @.epub

Though I generally find that using a loop is generally quicker,
shorter and safer (and you have more control over what's going
on):

(for f (./*) ebook-convert $f $f.epub)

(using a subshell to get a more deterministic behaviour upon
^C/^Z).

Here, assuming that "ebook-convert" supports the --
end-of-option delimiter (if it doesn't replace -p with -P and *
with ./*), you could also do:

autoload -Uz zmv # in ~/.zshrc

zmv -p ebook-convert '*' '$f.epub'

Or 

alias wzmv='noglob zmv -W' # in ~/.zshrc

wzmv -p ebook-convert * *.epub

zmv does some sanity checks which you could find useful here,
like that none of the destination files exist before starting
the moves.

In addition to zmv, you might also look at Functions/Zle/keeper in the
distribution.  It's set up to work with some ZLE key bindings, but it
also can be used standalone.

% source $^fpath/keeper(N[1])
% keep *
% for k in $kept; ebook-convert $k $k.epub

Or

% find . -name \*.mobi | keep

etc.

See https://en.wikipedia.org/wiki/Posting_style

Your lines are also too long (72 recommended maximum, so it
takes a few quoting layers to get to 80, the standard terminal
width), but that's probably down to you using an Apple mail
client. And I suppose those recommendations (including
top-posting) make less sense now that people use mobile phones
to read their emails (maybe not their emails about zsh though).

$ lastglob=(); print -r -- *(e['lastglob+=($REPLY)']) /(e['reply=($^lastglob.epub)'])
file1 file2 file1.epub file2.epub

See also:

$ print -r -- *(e['reply=($REPLY $REPLY.epub)'])

What’s top posting?

Can’t $lastglob be available in the same command? It would be in the same fork, I imagine …
`command * -d $lastglob`

[don't top post]

Yes, it's not possible to get anything like $lastglob, because globs
are expanded after forking¹ to run the external command, so no results
are available to the interactive shell for subsequent use.

¹ if you're not running an external command it would theoretically be
possible, but it would be an inconsistent interface.

Of course it's possible:

() { typeset -p argv } *
set -- *; typeset -p argv
l=( * )
for i in * ; typeset -p $i

Thanks. I needed this to be non-interactive, and I indeed created a function for it, I was just wondering if it was possible to get the glob in a magic variable or sth, which it seems it is not.

Clarification: this assumption is only important for the expand-word example, since vi mode uses different keybindings.

Assuming emacs keybindings, you can do:

ebook-convert *<TAB>{,.epub}

(where <TAB> will expand the glob)

or

ebook-convert * *<Ctrl+X>*.epub

(where "<Ctrl+X>*" is the default binding for the expand-word widget, which will expand the glob)

or even

() { for 1; do ebook-convert $1 $1.epub; done } *

which, unlike the previous examples, works for any number of files.  (It's an anonymous function with arguments.)

Is there a way to get the result of the last glob?
I want to do sth like this in a folder with only one file, somebook.mobi:

ebook-convert * *.epub

Which I want expanded to:

ebook-convert somebook.mobi somebook.mobi.epub
