What EPUB and PDB files are

EPUB

EPUB (Electronic Publication) is the most widely supported ebook format, used by Apple Books, Kobo, and most e-readers except Kindle. It supports reflowable text, images, and interactive content.

PDB

PDB (Palm Database) is the file format Palm OS handhelds used for their data, including ebooks in variants such as PalmDOC and eReader. It dates from the mid-1990s and few modern devices read it, so PDB books are best converted to EPUB.
