Why would you convert an epub to pdf? There is no ebook reader, other than kindles (for which the proper conversion would be to kf8), that can't handle epubs.

Send my public domain book to my grandma who doesn't know how to handle an epub? Convert it because it is easier to print as a .pdf with my particular setup?

There are all kinds of potential use cases for users of differing levels of technical sophistication.

Why wouldn't you provide an option to convert to .pdf?

You cannot -- Kindle ebooks are in a format called KFX (or AZW/mobi or AZW3, depending on when you got them), which this tool doesn't support as an input. If you wanted to do that, I'd just use Calibre, which has really comprehensive format conversion abilities: https://calibre-ebook.com Most Kindle ebooks have DRM as well, which I think is currently hard to remove -- there's a plugin for calibre that you could try.…

Calibre is great, but IMO it’s the wrong approach for this particular conversion. Use KindleUnpack instead, which is close to lossless. https://github.com/kevinhendricks/KindleUnpack This is a fantastic way to read books published by Tor on multiple devices. Now if only Tor would sell the ePub files on their website. (Tor eBooks are not DRMed.)

KindleUnpack doesn't seem to handle DRM though.

when I check the download stats for all my books, PDF downloads are more popular than all other formats.

I prefer epubs too, but apparently readers really like PDFs...

PDFs retain their formatting better and are much more readily accessible across devices, except for the smallest screens.

On the contrary! Why would you ever keep an epub file around? If somehow an epub file finds its way into my computer, the first thing that I need to do is to convert it to pdf to be able to read it with a reasonable viewer (or print it!). After the convesion, I delete the epub file; I really dislike this format and the associated software.

Which is also its downside when formatting is not critical. I want to be able to change the font size and have the text reflow correctly. With PDFs you end up with broken layouts if you don't view it exactly as formatted.

If you print your ebooks for some reason rather than buy used copies, granted you have to convert to pdf for that.

Why prefer an epub...

They have flowed text, and ebook readers let you customize font and font size so that the book's text adapts to you rather than you adapting to a particular combination of publisher quirks and zoom necessary to fit in a particular device's or app's viewable size.

They're generally smaller files.

And if there's something about the epub you don't like, you can actually fix it.

If a book is available in both PDF and epub formats, it's a reader's prerogative to pick the one they want, and there are specific types of books where PDFs might be preferable. However, if there's no original pdf, what is the objective of converting an epub to pdf in order to read it on a computer? Whatever you think you're accomplishing, I think you're mistaken. You end up with a pdf that looks exactly like how a typical ereader would display the epub. Minus the flowed text and font customizability, and probably with poorer navigation as well.

Where are you downloading content as epubs that you can't get as PDF?

And (another fun fact) if you want to email EPUBs to your kindle, just make the file extension .png (!?) and it will be automatically converted, without the need for Calibre.

Although who knows why you'd want to go without Calibre when it's so multi-functional?

I can download an epub on my mobile. I can email an epub from my mobile.

I can't run calibre from my mobile. I can rename .epub to .png and email that from my mobile.

Yes, I can host calibre somewhere else. No, my technologically savvy friends and family cannot. I also don't want them to depend on me to be able to convert an epub for their kindle when there's a trivial solution that doesn't require additional dependencies.
