Extract CAB archives.

Files never leave your device. Everything runs in your browser, nothing touches a server — tools you've used even work offline.
CAB is the archive format Windows itself ships in — drivers, installers and updates all travel as cabinets. When you need one file out of a driver package (or you are just curious), drop the .cab here: contents extract in your browser, each file its own download.
How it works
- Drop files anywhere on the page, click to browse, or paste with ⌘V.
- Pick a quality or preset — or set an exact target size and let the tool find it.
- Compress, compare before/after, and download — individually or as a ZIP.
From cabinet to anywhere
Extracted driver files usually go straight to Device Manager, but when a set of files should travel on, repack them via the archive tool into a ZIP or 7Z. Old software archives often nest formats — a CAB inside a ZIP inside an ISO all opens here, one layer per drop.
Frequently asked questions
Where do CAB files even come from?
Driver downloads, Windows Update payloads, installer internals (.msi files often embed cabinets) and printer packages. Vendors still ship raw .cab driver bundles, and manually extracting one INF or DLL from them is the classic use case.
Which CAB compression variants are supported?
MSZIP and LZX — which covers essentially every cabinet Microsoft tooling produces. Multi-part cabinet SETS (spanning several .cab files) need all parts and are not supported; single cabinets, the overwhelmingly common case, extract fine.
Can it open .msi or .exe installers too?
Not directly — those are container formats around cabinets. If you can get the .cab out (many installers unpack with /extract or similar switches), it opens here.
Is it private?
Yes. The archive is opened and unpacked on your own device — its contents are never uploaded, and a password, if one is needed, is used locally and never transmitted. The server does nothing but deliver this page. Want proof? Run one file through, switch your connection off, and run another — it still works.
