Both formats, briefly
HTMLZIN
HTMLZ is a book packed as ordinary web files: the HTML holding the text, a stylesheet, and the images, zipped together into one archive. Nothing sits behind a proprietary container, so this is the format to pick when you want to edit a book by hand, feed it to your own publishing script, or inspect how the markup came out of an earlier conversion. Calibre reads and writes it, which makes it a comfortable stopping point between two other formats. Choose HTMLZ when the file is a working copy rather than the version someone will read.
PDBOUT
PDB started life as the file container for Palm OS handhelds and became one of the first practical ways to carry novels in a pocket. The name covers several book layouts packed inside that container, PalmDOC and eReader among them, each holding the text, light formatting and bookmarks. Palm devices disappeared long ago, so a .pdb book usually surfaces from an old backup or memory card. Run it through the converter to get EPUB, AZW3 or PDF that a current reader will open.
