How do I convert epub to mobi using calibre?

Question

How do I convert epub to mobi using Calibre for this?

Answer 1

Yes, Calibre package contains a script called ebook-convert to convert ebooks between formats. You can install Calibre with

sudo apt-get install calibre

then

ebook-convert "book.epub" "book.mobi"

NB: Other formats are supported, too:

ebook-convert "book.azw3" "book.pdf"

Answer 2

I found a script for batch conversion:

for book in *.epub; do echo "Converting $book"; ebook-convert "$book" "$(basename "$book" .epub).mobi"; done

It works good for me, but the process is pretty slow.

Answer 3

Install calibre. Works with any arbitrary folder depth.

find . -name '*.epub' -type f -exec bash -c 'ebook-convert "$0" "${0%.epub}.mobi" --prefer-author-sort --output-profile=kindle --linearize-tables --smarten-punctuation --enable-heuristics' {} \;

Answer 4

As of November 2021. I had to run the command using sudo.

E.g

sudo ebook-convert book.epub book.mobi

I didn't need the quotes, but you can use them if your file name has spaces. E.g:

sudo ebook-convert "book one.epub" "book one.mobi"

Everything else works as described in the accepted answer above.

Answer 5

You can also do this without installing Calibre. This would be really handy on a Chromebook, for example. There is a free, online site called EPUB Converter that will let you upload the epub and it lets you then download the mobi equivalent.

Answer 6

Yes, you can use Calibre for epub to mobi conversion. They declare mobi as supported output format in their FAQ.

I don’t think there’s anything Ubuntu-specific in the question, so it would probably belong somewhere else.
