Is the algorithm selected for compression the most suitable?

[Ricky-Tigg]

Hello. A message integrated into the UI announcing a skipped task is displayed when the execution of a compression request would result in a file size superior than the original; I don't see anything inconsistent with that. However, could there exist an algorithm whose compression output is solely a file of smaller or equal size, which would make it eligible for inclusion in this program for practical purpose?
