CBZ (Comic Book ZIP) is functionally identical to CBR but uses ZIP compression instead of RAR. Because ZIP is an open format, CBZ is widely preferred by open-source comic management software such as Calibre, Komga, and Ubooquity. CBZ is now the de facto standard for digital comic distribution outside of proprietary platforms. Like CBR, it stores sequentially ordered images with no text layer, relying entirely on scan quality for readability.
Converting CBZ to PDB extracts the sequentially ordered images from the CBZ archive and repackages them within a PDB container. 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 converted PDB file retains the original book's content and structure for use on compatible devices.
PDB (Palm Database) is the native ebook format for Palm OS devices and eReader applications. Converting to PDB allows content to be read on Palm PDAs, Treo smartphones, and any device running the eReader application. Though Palm OS is obsolete, PDB conversion is still used in digital preservation workflows and by collectors of vintage mobile technology. The compact PDB format is also supported by several modern multi-format e-reader apps.
Comic archives convert to PDB as image sequences. Ensure the archive contains images in correct alphabetical/numerical order, as Calibre relies on filename ordering. High-resolution images produce larger output files; consider resizing images beforehand. PDB is a legacy format primarily for specific historical hardware. Verify your target device supports PDB before converting. For modern devices, EPUB or MOBI are better choices. Our conversion engine processes CBZ to PDB entirely in the cloud — no software installation needed. Files are deleted from our servers within 24 hours of upload.
