When Should You Use MPP vs KEY?

MPP vs KEY: Key Differences

• •The core technical difference: MPP relies on lossy compression whereas KEY 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: KEY 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 KEY files 5MB to 100MB with media.
• •Primary audience: MPP is built for project plans, gantt charts, task tracking scenarios, while KEY focuses on apple presentations, slideshows — pick the format that matches your output requirement.
