RarKit

Open any archive on your Mac — and know it came out intact.

RarKit opens RAR, ZIP, 7z, TAR and a dozen other formats, and creates ZIP, 7z and TAR. It looks inside before extracting, so you can pull out a single file instead of all of them.

Why another one

Most archive tools have a habit worth knowing about: when they hit something they can't handle, some of them write the file anyway and report success. You end up with a folder full of files that are the right size, the right names, and completely empty inside. Nothing warned you.

RarKit reads back what it writes and checks it against the original. If it can't confirm a file came out intact, it says so and removes what it started. An archive that won't open is better than one that looks fine and isn't.

What it does

Opens RAR, ZIP, 7z, TAR, GZIP, BZIP2, XZ, ZSTD and more — detected by content, not by the name, so a mislabelled file still opens.
Looks inside before extracting anything, so you can take one file and leave the rest.
Creates ZIP, 7z and TAR, with AES-256 encryption for ZIP.
Splits large archives into numbered pieces, and reassembles them from the first one.
Says what went wrong in a sentence you can act on, instead of an error code.

Honest limits

RarKit cannot create RAR archives. Neither can any other app on the Mac App Store: the format belongs to RARLAB and its licence permits reading but forbids writing. Anyone claiming otherwise is not being straight with you.

Privacy

RarKit has no networking code at all. Your files never leave your Mac because the app has no way to send them anywhere. See the privacy policy.
