GrandPerspective vs MediaOptim: Honest Comparison (2026)
An unbiased look at GrandPerspective (Free) and MediaOptim ($14.99 one-time). We'll tell you when GrandPerspective is the better choice.
Quick Verdict
GrandPerspective is a great free way to see what is filling your disk: every file is a rectangle sized by how much space it uses. But like every disk analyzer, the only fix it offers is deleting. If the big rectangles are videos and photos you want to keep, MediaOptim compresses them instead.
