Simple switch for lossless compression modes

[kishaningithub]

It would be great if this tool can support lossless compression modes as a simple toggle switch

Users can simply change between lossy and lossless

Hi kishaningithub,

Optimus is in the Beta phase, I believe there will be many additions and improvements over time.
