When Should You Use POTM vs XLSB?

POTM vs XLSB: Key Differences

• •The core technical difference: POTM relies on lossless compression whereas XLSB uses lossless compression.
• •Both formats share lossless compression, so quality behavior is similar across the two — file size differences come from algorithm efficiency rather than compression philosophy.
• •Alpha channel support: XLSB lacks transparency support.
• •XLSB files tend to be differently sized than POTM
