I’ve done It before. It’s just highly dependent on the PDF. What software made the pdf? What format was it in prior to being a PDF? Is it a scanned image of text? Or does it have actual text.

Another option, that might work better, might not, though it would be more work, is use something like Microsoft Word first. Word can open a PDF and “convert” it to Word format. After that, you spend a lot of time fixing all the formatting which will probably be fucked up.

And then, once you have a nice clean Word doc, convert that to epub.

Sortaaaa, it’s pretty weak from what I remember and mostly served to give you a reason to explore more of the sandbox and use the different features of the game.
