About formats

POTM (PowerPoint Template with Macros) is a macro-enabled template format for Microsoft PowerPoint, introduced with Office 2007 as part of the Office Open XML family. POTM combines the template functionality of POTX — providing reusable slide masters, layouts, themes, and design foundations — with the ability to embed VBA (Visual Basic for Applications) macro code that executes in presentations created from the template. The format is a ZIP archive containing the standard XML parts for slide masters, layouts, and themes, plus a vbaProject.bin stream housing the VBA project. This combination enables organizations to distribute not just visual consistency but also functional automation: every presentation created from a POTM template inherits both the design system and the programmatic capabilities built into it. Common use cases include templates that automatically populate slides with data from corporate systems, enforce content approval workflows, insert standardized disclaimer slides, or provide custom ribbon tabs with organization-specific tools. One advantage is embedded workflow automation — a POTM template can include initialization macros that configure the presentation environment, add custom menu options, and connect to external data sources the moment a new presentation is created from it. The distinct .potm extension serves a security purpose as well, enabling administrators to apply differentiated trust policies for macro-containing templates versus standard POTX files. POTM is supported exclusively in Microsoft PowerPoint desktop editions where VBA execution is available.

PDB (Palm Database) is a generic database container format created by Palm, Inc. for the Palm OS platform, first appearing with the original PalmPilot in March 1996. In the ebook context, PDB files most commonly use the PalmDOC or Plucker encoding to store readable text with basic formatting. The format consists of a 78-byte header identifying the database name, creation date, and record count, followed by a record index table and the data records themselves. PalmDOC-encoded PDB files use a simple LZ77-based compression scheme to pack plain text efficiently, while Plucker extends this with HTML rendering, image support, and hyperlink navigation. PDB ebooks powered a thriving mobile reading ecosystem years before dedicated e-readers existed — millions of Palm OS users carried entire libraries on devices like the Palm V, Tungsten, and Treo handhelds. A primary advantage is extreme simplicity: the flat record structure and minimal overhead mean PDB files parse instantly even on severely constrained hardware with limited memory and processing power. The open, well-documented structure is another strength, having spawned numerous reader applications across Palm OS, Windows, and later mobile platforms. Though the Palm platform is long discontinued, PDB ebooks remain accessible through conversion tools and readers like Calibre, and the format holds historical significance as one of the earliest practical mobile ebook solutions.

Frequently Asked Questions

Why convert POTM to PDB?

PDB image format is used by Palm OS devices to store bitmaps in database records — useful for retro computing projects or Palm OS application development.

How do I open PDB image files?

Palm OS emulators, pilot-link utilities, and tools like ImageMagick can read PDB image databases. Some retro PDA enthusiasts use dedicated Palm viewers.

Are macros from POTM kept in PDB?

No. PDB image format stores only bitmap data in Palm database structure — all VBA macros and template metadata are discarded during conversion.

What resolution do PDB images use?

PDB bitmaps conform to Palm OS display constraints, typically 160x160 or 320x320 pixels depending on the target device generation.

Can I use PDB on modern devices?

PDB image files are designed for Palm OS. On modern systems, they are mainly opened through emulators or converted to contemporary formats.

Does this conversion cost anything?

Convertio offers POTM to PDB conversion for free. Premium plans unlock higher limits for batch processing and larger uploads.
