PDB (Palm Database) was the primary ebook format for Palm OS devices and the Palm Reader application. It was one of the earliest widely-adopted portable ebook formats, thriving during the Palm PDA era of the late 1990s and 2000s. PDB files store text with basic markup and are notable for their compact size. Although Palm OS is long defunct, many classic ebook titles from that era survive only in PDB format, making conversion to modern formats essential for continued access.
Converting PDB to HTLMZ involves parsing the proprietary PDB binary structure and reconstructing the text and metadata as a HTLMZ file. Our conversion service uses Calibre, the gold-standard open-source ebook management tool, ensuring that text encoding, chapter markers, and embedded assets are faithfully transferred. The resulting HTMLZ package can be unzipped, edited as HTML, and re-converted to any ebook format.
HTMLZ is a zipped HTML format that Calibre uses as an internal editing format. Converting to HTMLZ produces a human-readable ZIP containing HTML, CSS, and images that can be manually edited and then re-converted to any other ebook format. It is the best choice when you need to inspect or modify an ebook's raw HTML structure before final conversion. HTMLZ is not intended as a final delivery format but as a powerful editing intermediary.
After downloading the HTMLZ file, rename it to .zip and unzip to access the HTML and CSS files directly. Edit them in any text editor, re-zip the folder, and rename back to .htmlz before importing into Calibre for further conversion. Our conversion engine processes PDB to HTLMZ entirely in the cloud — no software installation needed. Files are deleted from our servers within 24 hours of upload.
