When Should You Use XLAM vs PPT?

XLAM vs PPT: Key Differences

• •XLAM uses lossless compression while PPT uses lossy compression — this is the fundamental technical difference between the two formats.
• •Moving from XLAM (lossy) to PPT (lossy) means the output file will be significantly smaller — but at the cost of some visual fidelity.
• •How transparency is handled: PPT does not support alpha channels — transparent areas in the source will become opaque.
• •Storage footprint: 50KB to 5MB depending on complexity for XLAM vs 100KB to 30MB for PPT.
• •Primary audience: XLAM is built for excel automation, custom formulas, business workflow tools scenarios, while PPT focuses on legacy presentations, older systems — pick the format that matches your output requirement.
