BZ Converter > Convert BZ File to 7Z / RAR / TAR / TAR.BZ2 / TAR.GZ / ZIP Format

What does the BZ Converter do?

BZ files are typically the compressed form of a single file; they are not a “multi-file archive”.

This tool first decompresses the BZ file and then repackages it according to the selected target:

• Step 1: Decompress BZ (obtain a single file)
• Step 2: Generate output based on target selection:
  • ZIP/7Z/RAR: Place the obtained file into this archive (generate a single-file archive)
  • TAR: Place the obtained file into a TAR package (single-file tar)
  • TAR.GZ: TAR package > gzip compression (Linux standard)
  • TAR.BZ2: TAR package > compress with bzip2 (tar.bz2)

Smart content recognition (must write)

Some users send it as “file.bz” but it extracts .tar. In this case, the tool:

• offers the option: “The decompressed file appears to be a TAR package. If you want, I can transfer the folders it contains to the archive as is.”

This enhances the conversion; because the user won’t be surprised by “why did I get a single file output?”.

Transformations inside

• BZ to 7Z
• BZ to RAR
• BZ to TAR
• BZ to TAR.BZ2
• BZ to TAR.GZ
• BZ to ZIP

Which format should I choose?

Clear guide that clears the user’s mind:

• ZIP: The widest compatibility, the default if you want everyone to open it.
• 7Z: Modern archive standard, for those who want to consolidate archives into a single type.
• RAR: Some agencies/institutions say “send RAR”; if not mandatory, ZIP causes fewer surprises.
• TAR: No compression, just packaging; Linux workflow.
• TAR.GZ: tar + gzip; the most common compressed package in the Linux world.
• TAR.BZ2: tar + bzip2; smaller in some content, generally slower.

How to use? (single interface)

1. Upload your BZ file
2. The tool analyzes the file:
   • Is it BZ or BZ2 (format distinction)
   • the name and size of the single file to be decompressed
   • is the decompressed output a TAR (smart detection)
3. Select the target format
4. (Optional) select settings:
   • compression level (fast/balanced/maximum)
   • output name
   • archive password (if ZIP/7Z/RAR supports it)
   • “Extract TAR contents and transfer folders” (if the decompressed file is TAR)
5. Convert
6. Download single file

Settings (real, useful set)

Compression level

• Fast: time prioritized
• Balanced: default recommendation
• Maximum: size prioritized

Password (optional)

Adds a password to the target archive. Generally, there is no password on the BZ side; encryption occurs at the archive layer (ZIP/7Z/RAR).

Output name standard

Recommendation: originalName_target.ext

Ex: file_zip.zip, file_targz.tar.gz

Error messages (reduce support costs)

• Unsupported BZ type: “This file is not in the expected format of bzip2 (.bz2) or bzip (.bz).”
• Corrupted compression: “File is damaged or missing. Decompression process could not be completed.”
• Output could not be generated: “The format you selected is currently not supported. Try ZIP or TAR.GZ.”

Usage scenarios

• Convert a .bz file coming from a Linux server to a ZIP that can be opened on Windows
• Make a TAR.GZ from the .bz extracted .tar package
• Convert to Convert ARC Archive to 7Z and Download”>7Z to store a single file as a modern archive

FAQ

Is BZ an archive?

Generally no; it is a single file compression. For multiple files, tar + compression is used.

Are BZ and BZ2 the same?

No; they may be different format families. The tool must distinguish.
