Format Information
HTMLZ
HTMLZ (HTML ZIP) is a compressed ebook format that packages HTML content, stylesheets, and images into a single ZIP archive. It serves as a useful intermediate format for ebook conversion workflows, preserving the full HTML structure and styling of the content. HTMLZ is supported by Calibre and is particularly useful for custom ebook processing pipelines and format migration.
PDB
PDB (Palm Database) is an ebook format originally designed for Palm OS devices. It encompasses several sub-formats including PalmDOC and eReader, making it one of the earliest mainstream ebook formats. PDB files can contain text, basic formatting, and bookmarks. While Palm devices are no longer manufactured, PDB remains relevant for accessing legacy ebook libraries and converting older collections.
