SkoonMac is eight quiet tools in one window. Each one answers a single question about your disk, shows you a preview first, and never removes anything you did not choose.
Screenshots and videos rewritten to HEIC and HEVC — the same quality class, in far less space.
Most of a full disk is pictures and clips saved in heavy older formats. Compress re-encodes them to the modern formats your Mac already uses, keeping the image and shedding the weight. Preview every before-and-after, convert only what you choose, and watch the space come back. Originals go to the Trash, so the change is always reversible.
The rest of the suite
SkoonMac finds true duplicates by reading file contents, not just names, so it never confuses two different files that happen to share a name. You pick which copy to keep; the rest go to the Trash.
The biggest forgotten files rise to the top, sorted by size and fully previewable. Old disk images, exports and downloads you meant to delete months ago — finally visible, finally easy to clear.
A Safe Clean default that only touches user-level caches, logs and Trash — nothing deeper. Anything more is an explicit, clearly labelled choice. The app is built to never dig where it should not.
A calm, legible map of your disk — folders sized to scale, so the space finally makes sense at a glance. No frantic colour, no spinning sunbursts. Just clarity.
The "System Data" that quietly swells in your storage settings, explained in plain language and made reclaimable — safely, and only where it is genuinely safe to do so.
Gentle, on-device insight into what is growing over time, so clutter never creeps back unnoticed. Computed locally and shown to you alone — nothing about it leaves the Mac.
Remove an app together with the support files, caches and preferences it scattered around, so nothing lingers in the corners after it is gone.
The promise under every tool
Preview first. Trash, not delete. Nothing sent away.
Every one of these tools follows the same three rules. They scan into a non-destructive preview, they move removals to the Trash so you can undo, and they compute everything on your Mac with no telemetry.
That is what makes SkoonMac calm to use: there is nothing to be afraid of, because there is nothing irreversible and nothing leaving your machine.
