calibre tends to work pretty well
Yeah this is what I use, it works well. But now that zotero can handle epubs, I hope I never have to do it again.
Second this, it's very good.
It's been a long time since I've used this tool but it used to be very good:

Can't say for sure that it's still good but if you want to do it once without installing a program and fiddling around with all the settings then that should probably work just fine.
Otherwise calibre offers a very feature rich ebook conversion tool but goddamn do I only understand half of the functions in that app. Still it's by far the most powerful and feature rich app for ebooks.
Sincerely. Why??
Right?
Occasionally I've been known to make epubs out of PDFs. It's painstaking work and it takes hours to comb through each page manually when doing this. (There's a few on LibGen of my work like Blood In My Eye by George Jackson and Dimitrov's Selected Speeches, from the publishing date prior to this work being heavily edited in the post-Stalin era.)
The thought of someone undoing all that work almost makes me want to cry lol.
I could potentially see doing it for printing but I genuinely can't think of any other reason.
In case you ever find anyone who's doing this, comrade Rightenberg has written a program for turning PDFs into home-printed books/pamphlets here:

Never used it but I trust the guy - he wrote his own damn programs so he could narrate audiobooks from printed material.
Spread the word if it ever comes up in future.
probably downloaded a book from libgen that was only available as an epub
