When Should You Use XLS vs MD?

XLS vs MD: Key Differences

• •The core technical difference: XLS relies on lossy compression whereas MD uses lossless compression.
• •Moving from XLS (lossless) to MD (lossless) means the output file will be larger — but every bit of the original is preserved.
• •Alpha channel support: MD lacks transparency support.
