I'll tell you clearly and loudly: I don't like Calibre! So, how can I convert PDF to ePUB without it?

We know you don't like Calibre... but have you tried its CLI conversion tool?

The Calibre install provides the command ebook-convert that will handle what you want, and there's no need to run Calibre.

ebook-convert file.pdf file.epub

is all that's required.

If the output looks a little wrong - try this

ebook-convert file.pdf file.epub --enable-heuristics

It will try a "smart" way to convert. Not perfect, but can work well in most conversions.

    Any way to make it work with 2 column documents? The --enable-heuristics flag does not work well with those.

    According to their website, multi-column PDFs are not supported.

    Wow thanks. For multiple PDF files within a folder I used this after cding to the directory: find ./ -iname "*pdf" -type f | while read f; do echo -e "\e[1mConverting file $f \e[0m" ; ebook-convert "$f" "${f%.pdf}.epub" --enable-heuristics ; done

    note that if you don't have the ebook-convert command, you may have installed calibre through flatpak or snap. Uninstall your existing calibre through the software center, or flatpak remove, or snap remove and then install with apt

    @PrashantTapase - I don't see why you should have any trouble. The GUI offers the same options as the CLI. The GUI has more of a per-device set of rules. You can opt on how files are converted when they are transferred according to what reader you plugged in. A Kobo reader uses epub, Kindle has mobi. Calibre should pick that up automatically, but you can always use the convert icon to fine tune what you have in your library.

LibreOffice has an epub exporter extension, so you can install the LibreOffice PDF importer extension, import your PDF, and then export to epub.

Have a look at www.convertfiles.com, you can easily convert .pdf to .epub using their free online conversion tool.

This is not a direct answer to the question, but for people who want to read PDFs on an e-reader and are finding it cumbersome, one solution may be to crop the margins of the PDF, and read in landscape mode. That works acceptably well for me on my e-reader in any case. There are many PDF croppers out there. Just search for "pdf crop" or "pdf trim".
