When Should You Use PPSM vs PPSX?

PPSM vs PPSX: Key Differences

• •PPSM and PPSX diverge on compression: lossless compression for the source, lossless compression for the target.
• •Since both PPSM and PPSX use lossless compression, the quality characteristics are comparable — differences in file size come down to how efficiently each format implements compression.
• •Alpha channel support: PPSX handles transparency.
• •File sizes: PPSM files typically range N/A and PPSX files N/A.
• •Primary audience: PPSM is built for interactive kiosks, automated presentations with macros scenarios, while PPSX focuses on slide presentations, kiosk displays, automated demos — pick the format that matches your output requirement.
