Did You Know? 🤔

MOBI (Mobipocket) is an eBook file format that was primarily used for Kindle eBooks, offering good compatibility with Amazon's ecosystem.

PDB (Palm Database) is a legacy format originally designed for Palm OS devices, supporting eBooks, databases, and applications.

Both MOBI and PDB formats support text-based content, but PDB is particularly valuable for users of classic Palm devices and other legacy eReaders.

Converting from MOBI to PDB allows you to read your eBooks on Palm OS devices, older mobile phones, and specialized readers that support the PDB format.

PDB files were widely used in the early days of mobile reading and still maintain a niche following among collectors and users of vintage mobile devices.
