Palm-Ready Output

Most converters skip Palm formats entirely. Convertio turns your PPSM slides into PDB images that work directly with PalmOS ImageViewer and Palm emulators.

Compact File Sizes

PDB images are designed for memory-constrained Palm devices. PPSM slides are scaled and optimized to produce lightweight files suited for low-resource environments.

Convert from Anywhere

Run the PPSM to PDB conversion from any modern browser — desktop, tablet, or phone. No Palm development tools or PowerPoint installation required.

About formats

PPSM (PowerPoint Slideshow with Macros) is a macro-enabled slideshow format in Microsoft PowerPoint, introduced with Office 2007 as part of the Office Open XML family. PPSM combines the auto-play slideshow behavior of PPSX with the VBA macro capabilities of PPTM — opening a PPSM file launches it directly into full-screen presentation mode while allowing embedded macro code to execute during the slideshow. The format is structurally a ZIP archive containing the same XML slide parts as other OOXML presentation formats, plus a vbaProject.bin stream housing the VBA project. This combination is particularly valuable for interactive presentations: macro-driven slideshows can respond to user input, navigate non-linearly between sections, query external databases, update content in real time, and log audience responses during training or assessment sessions. One advantage is interactive presentation capability — PPSM enables quiz-style presentations where clicking answer buttons triggers immediate scoring feedback, branching paths, or data recording, all invisible to the audience. The macro-enabled slideshow format also supports self-contained automation: a PPSM file can run initialization routines on launch, configure the display environment, and clean up resources on exit without any manual intervention. As with all macro-enabled Office Open XML formats, the distinct .ppsm extension helps administrators enforce security policies that differentiate between trusted macro content and standard presentations. PPSM is supported exclusively in Microsoft PowerPoint desktop editions.

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 PPSM to PDB?

PDB images are used by PalmOS ImageViewer. Converting PPSM slides to PDB lets you display presentation content on Palm devices, emulators, or retro computing setups.

What opens PDB image files?

PalmOS devices with ImageViewer, Palm Desktop software, Palm emulators like PHEM, and ImageMagick can all read PDB image files. Some specialized viewers also support the format.

Is PDB a color format?

PDB images support both grayscale and limited color palettes depending on the target Palm device. Most PDB images use grayscale to match older Palm screen capabilities.

Do PPSM macros transfer to PDB?

No. PDB image files contain only bitmap pixel data sized for Palm displays. All VBA macros and embedded logic from the PPSM are completely stripped.

Can I use this converter for free?

Yes — Convertio provides PPSM to PDB conversion free of charge. Upgraded plans offer larger file allowances and faster queue priority.

How big are the output images?

PDB images are inherently compact — designed for small Palm screens with limited memory. Slide content is scaled down to fit Palm display dimensions.
