Convert B6Z to TAR

Verified by Adam B.· reviewed by FE Editorial ·updated Sep 1, 2026
QUICK ANSWER
Is it possible to convert B6Z to TAR?
Yes - B6Z converts to TAR.

There is no one-click .b6z-to-.tar tool. You unpack the B6Zip archive with 7-Zip, p7zip or Keka, then bundle the extracted files back up as a .tar. Note that .tar stores no compression, so the result is larger than the original.

Why convert B6Z to TAR?

.b6z is B6Zip's own LZMA2-compressed archive, while .tar is an uncompressed bundle common on Linux and macOS. People move to .tar when they need a format that native Unix tools and shell scripts read without the B6Zip app.

How to convert B6Z to TAR

p7zip (Linux / command line) FREE

Extract with 7z x archive.b6z -oout/, then bundle the folder with tar -cf archive.tar out/.

Keka EASIEST

Drop the .b6z on Keka to extract it, then drag the resulting folder back onto Keka set to the TAR output format.

7-Zip FREE

Right-click the .b6z and choose 7-Zip > Extract Here, then re-add the files with archive format set to tar.

About these formats

.B6Z B6Z Archive

A .b6z file is a compressed archive made by B6Zip, a macOS utility that packs one or more files into a single container. It uses LZMA2 compression by default and supports optional AES-256…

.TAR Tape Archive

A TAR file (also called a tarball) bundles files and folders into one archive but does not compress them. That is why you almost always see it as .tar.gz or .tgz, with gzip added on top. On…

Quality & what to watch

  • .tar applies no compression, so the .tar will be noticeably larger than the compressed .b6z.
  • AES-256 encryption and any recovery data in the .b6z are not carried into a plain .tar.
  • This is a two-step (unpack then repack) process; no tool converts .b6z straight to .tar.

Frequently asked questions

Can I convert .b6z to .tar in one step?
No. You must extract the B6Zip archive first, then create a new .tar from the extracted files.
Will the .tar be smaller than the .b6z?
No, it will be larger, because .tar stores files without any compression.
Do I need the B6Zip app?
Not necessarily. 7-Zip, p7zip and Keka can all open .b6z archives to extract the contents.
What if the .b6z is password-protected?
You must supply the password when extracting; the .tar you create afterward is unencrypted unless you encrypt it separately.
