When Should You Use PPSM vs MPP?

PPSM vs MPP: Key Differences

• •The core technical difference: PPSM relies on lossless compression whereas MPP uses lossy compression.
• •Moving from PPSM (lossy) to MPP (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •How transparency is handled: MPP does not support alpha channels — transparent areas in the source will become opaque.
• •MPP files tend to be differently sized than PPSM
• •PPSM is optimized for interactive kiosks, automated presentations with macros while MPP is designed for project plans, gantt charts, task tracking — choose based on your specific workflow needs

Troubleshooting PPSM to MPP Conversion

• !PPSM to MPP formatting looks off → complex layouts with tables and columns may shift between formats
• !Fonts render differently in MPP → embed fonts or use standard web-safe fonts before converting
• !Images missing from the MPP output → ensure images are embedded in PPSM, not linked externally
• !Tracked changes disappeared after converting PPSM to MPP → some document formats don't support revision tracking
