Archivers for ZIP, 7Z, RAR, and TAR files on Windows and Mac

12 programs reviewed · Updated August 9, 2026

Compression tools do two jobs: they shrink files so they take up less space, and they bundle many files into a single archive that is easier to move or email. Windows and macOS both open ZIP archives on their own, so the reason to install a dedicated archiver is almost always something else — RAR support, stronger encryption, split archives, or a faster multi-core compressor.

The format matters more than the app. ZIP is the universal choice when the person on the other end may be using anything. 7Z usually produces the smallest result and supports AES-256 encryption, but the recipient needs a 7Z-capable tool. RAR is a proprietary format: many tools can extract it, and only WinRAR and RARLAB tools can create it.

This hub covers the archivers we document in detail, the trade-offs between them, and the step-by-step guides that solve the specific problems people actually search for — opening a 7Z file on Windows 11, extracting RAR on a Mac, or splitting an archive that is too large to upload.

What to look for

  • Format coverage: check whether you need to create RAR archives or only extract them.
  • Encryption: AES-256 with encrypted file names is the meaningful bar, and only some formats support it.
  • Multi-core compression, which makes a large difference on modern CPUs.
  • Shell or Finder integration, so compressing is a right-click instead of a separate app.
  • Licensing: several strong archivers are free and open source, so paying is a choice, not a requirement.

Frequently asked questions

Do I need extra software to open a ZIP file?

No. Windows 10, Windows 11, and macOS all extract ZIP archives from the file manager. You need a third-party archiver for formats such as 7Z and RAR, or for features like AES-256 encryption and split archives.

Which format compresses best?

For most mixed file sets, 7Z with LZMA2 produces smaller archives than ZIP, and RAR sits between the two. Already-compressed data such as JPEG, MP4, or MP3 barely shrinks in any format.

Is it safe to open an archive from an unknown sender?

Extracting an archive is generally safe, but the files inside are not. Treat executables, installers, and macro-enabled documents from archives you did not expect as untrusted, and scan them before opening.
