Your files stay yours.
Scanning and analysis run on your computer, even across a full disk.
Space makes sense here.
See what fills your computer. Follow the big folders. Review every removal before it happens.
Real render of the Mac app · demo files
Follow the space.
Go from a block on the map to its folder, its files and why it’s there.
Decide before Trash.
Stage items in Cleanup, read the reason, then confirm the final move.
The film · 0:49
Every gigabyte has a name.
Your Mac says it’s full. freedisk.space shows you what’s filling it: the map, the space macOS hides, a cleanup that only ticks what rebuilds, and Put Back for anything you change your mind on.
Real app screens with demo files · “Where’s the rest?” arrives in the next update
Inside the Mac app
From “where did it go?”
to “there it is.”
Start with the map, decide what goes, and change your mind later.
See the whole picture
Every folder becomes a block sized by the space it takes. Click one to go inside; hatched blocks are the ones that can be freed.

Decide what goes
Only caches and build files that rebuild by themselves start ticked. The receipt says what you get back, and that it all goes to the Trash.
Trash firstPut Back
Find anything
Jump to a folder or a file, run a cleanup, or search with a query like size>500MB age>1y.
⌘Kfrom any screen
True duplicates only
Files with exactly the same contents, whatever their names. Files inside projects and apps are never ticked for you.
Byte for byteOldest copy kept
Change your mind
Every cleanup is listed. While it is in the Trash, Put Back returns it to the same place with the same name.

Reinstall is safe. Build output and caches; the next build makes them again.
- See the project, not just the path.
Artifacts grouped by tool and project, so you can see where the space sits.
- Know the rebuild cost.
Lockfiles and recent work tell an easy rebuild from one that needs care.
- Keep the decision yours.
Only what rebuilds by itself is offered for cleaning; the rest says Review.

Why freedisk.space
Useful answers beyond “what’s large.”
Storage is more than a list of big files. These are the promises the app is built around.
Trash first. Put Back any time.
Nothing is removed in the background. Cleanups go to the Trash, and History & Put Back returns them to the same place, with the same name, while they are there.
Honest about duplicates.
APFS clones can look like copies while sharing the same blocks on disk. freedisk.space labels shared storage and keeps what it says you will get back conservative.
Open source, down to the Trash.
The code that moves a file is seven lines long, and you can read it. MIT licensed. Read it on GitHub
Mac and Windows.
Apps for macOS 14 or later, on Apple silicon and Intel, and for Windows 10 and 11.
Free. No account.
No trial, no subscription, no sign-in. Scans run on your computer and stay there.
