## What is ReadPDB?

Bring part of your .pdb ebook library back to life.

ReadPDB opens ebook documents in the iSilo 3 format, stored as Palm Database (.pdb) files. The .pdb extension is shared by several unrelated Palm-era formats, so not every .pdb file will open. Import books directly from the Files app and read them on your iPhone or iPad—no account or internet connection required.

Features

• Import one or more compatible .pdb books from the Files app
• Render supported text formatting and internal links
• Automatically return to your last reading position
• Adjust text size for comfortable reading
• Choose Light, Dark, or System appearance
• Navigate with Back, Forward, and Home controls
• Highlight passages for later reference
• Share selected text using the standard iOS share sheet
• Remove imported books from your library at any time

Offline reading

ReadPDB has no accounts, subscriptions, advertising, analytics, or tracking. Your books remain on your device and are never uploaded or processed by external servers.


The following are not currently supported:

• Password- or registration-protected books
• Damaged or corrupted files
• PalmDOC, Mobipocket, eReader, Plucker, and other non-iSilo .pdb formats
• PDF documents
• Embedded images within documents

ReadPDB does not include, sell, or download books. Import only documents that you own or have permission to use.
