Good to know

  • a BZ file holds a single compressed file, so the result is a TAR.BZ2 archive with that one file in it.
  • BZ is an old format that today's computers rarely open by themselves. TAR.BZ2 files are much easier to open, share and keep.
  • Symbolic links, hard links and special files (such as devices) are left out of the result for safety; the page tells you when it does this.

Frequently asked questions

Is converting BZ to TAR.BZ2 free?

Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.

Are my BZ files uploaded anywhere?

Files up to 200 MB never leave your device: ConvertKitty runs 7-Zip inside your browser. Only larger files, or formats your browser cannot handle, are sent to our server, over an encrypted connection, and deleted 72 hours after the conversion. The button says "Upload and convert" whenever that happens.

How large can the BZ file be?

Files up to 200 MB are converted right in your browser. Larger files, up to 1 GB, are converted on our server.

Will the folders inside my BZ be kept?

a BZ file holds just one file, so there are no folders to keep: the TAR.BZ2 will contain that one file.

Can I convert several BZ files at once?

Yes. Add as many files as you like; they are converted one after another, and each one gets its own Download button.
