How MOBI Handles PDB Data

Dynamic range — the span from darkest to brightest values — is handled carefully during this conversion. PDB Palm eBook preserves the full range. Mobipocket eBook maintains the complete dynamic range. Xonvert preserves embedded metadata (EXIF, XMP, ID3 tags, etc.) whenever the Mobipocket eBook format supports it. Format-exclusive metadata fields that have no equivalent in Mobipocket eBook are gracefully omitted without affecting the converted content. Quality in this conversion depends primarily on your source file. A high-quality PDB Palm eBook input produces an excellent Mobipocket eBook output. Since the target format is lossless, output quality matches your input exactly.

This is a cross-category conversion from Ebook (PDB Palm eBook) to eBook (Mobipocket eBook). While these formats serve different purposes, Xonvert extracts the compatible data from your PDB Palm eBook source and maps it into the Mobipocket eBook format. Ebook files typically contain legacy Palm OS eBooks and vintage PDA content, while eBook files are used for old Kindle content and legacy ebook libraries. The conversion bridges these two domains, allowing you to repurpose your content across different workflows.
