When Should You Use MPP vs PUB?

MPP vs PUB: Key Differences

• •The core technical difference: MPP relies on lossy compression whereas PUB uses lossy compression.
• •Neither format changes compression philosophy — both are lossy compression — so any size differences are due to encoding efficiency, not a shift in quality approach.
• •How transparency is handled: PUB does not support alpha channels — transparent areas in the source will become opaque.
• •File sizes: MPP files typically range 500KB to 50MB for large projects and PUB files 500KB to 50MB with images.
• •MPP is optimized for project plans, gantt charts, task tracking while PUB is designed for desktop publishing, flyers, newsletters — choose based on your specific workflow needs
