TB2 Converter

How to Convert TB2 to Any Format

1. Upload Your TB2 File: Drag and drop your .tb2 archive or click "+ Add Files" — you can also pull from Google Drive or Dropbox. Batch is supported; drop in several .tb2 (or .tbz2) archives and each one converts on its own.
2. Pick an Output Format: ZIP is preselected for the widest compatibility. Switch the output to TAR.GZ, TAR.XZ, 7Z, RAR, TGZ, or plain TAR depending on where the archive is headed — every option re-packs the same files into the new container.
3. Choose Single or Individual Archives: When you upload more than one file, the "Combine?" control lets you merge everything into one archive (Single Archive) or produce a separate archive per input (Individual Archives). Defaults are tuned for typical use, so most people leave the Advanced Options alone.
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Popular TB2 Conversions

• TB2 to ZIP — the universal choice; ZIP opens natively on Windows, macOS, and Android without extra software
• TB2 to TAR.GZ — keep a Linux-native tarball but swap bzip2 for faster gzip compression and decompression
• TB2 to TAR.XZ — move to the xz/LZMA compressor for a tighter archive than bzip2 produces
• TB2 to TAR — strip the bzip2 layer entirely for an uncompressed tarball that's fast to read
• TB2 to 7Z — repackage into the high-ratio 7-Zip format used widely on Windows
• TB2 to RAR — produce a RAR archive for tools and workflows that expect it
• TB2 to TGZ — the short single-extension spelling of TAR.GZ, identical contents

Why Convert a TB2 File?

A .tb2 file is a TAR archive that has been compressed with bzip2 — it is the same thing as a .tbz2 or .tar.bz2 file, just written with a shorter single extension. TAR (tape archive) bundles many files and folders into one stream while preserving Unix permissions and directory structure; bzip2 then compresses that stream using the Burrows-Wheeler Transform, which generally squeezes text-heavy data smaller than gzip can, at the cost of being slower and more CPU-intensive. This combination was common for distributing Linux software and source code, though the xz/LZMA compressor is now frequently preferred when the smallest possible download matters.

The reasons people convert away from TB2 are almost always about reach and tooling:

• Windows and cross-platform sharing. Windows, macOS, and Android open ZIP natively with a double-click. A .tb2 usually needs a dedicated tool like 7-Zip, PeaZip, or the tar command, so converting TB2 to ZIP is the simplest way to hand an archive to someone who isn't on Linux.
• Changing the compressor, not the contents. If bzip2's slow decompression is the bottleneck, convert to TAR.GZ for faster handling; if you want a tighter archive than bzip2 manages, convert to TAR.XZ. Both keep the Unix-friendly tarball structure.
• Stripping compression for speed. Converting TB2 to plain TAR removes the bzip2 layer, leaving an uncompressed archive that build scripts and indexing tools can read without spending CPU on decompression.
• Fitting a different toolchain. Some Windows utilities and corporate environments expect 7Z or RAR. Repackaging keeps the files intact while matching whatever the receiving software speaks.

Converting never edits the files inside — it unpacks the original archive and re-packs the identical contents into the new container, so a TB2 of source code becomes a ZIP, 7Z, or TAR.GZ of the exact same source code.

TB2 vs Common Conversion Targets

Frequently Asked Questions

What is a .tb2 file?

A .tb2 file is a bzip2-compressed TAR archive — byte-for-byte the same kind of file as .tbz2 and .tar.bz2. TAR bundles the files and folders together (keeping Unix permissions and paths), and bzip2 compresses that bundle using the Burrows-Wheeler Transform. The short .tb2 and .tbz2 spellings exist mainly because older Windows and DOS-style filesystems disliked the double .tar.bz2 extension. To get at the contents you decompress with bzip2 first, then extract the TAR — or just upload it here and convert it to a format your software opens directly.

Is TB2 the same as TBZ2 and TAR.BZ2?

Yes. .tb2, .tbz2, and .tar.bz2 are three spellings of the identical format: a TAR archive compressed with bzip2. There is no difference in the data — a tool that reads one reads all three. Renaming a .tar.bz2 to .tb2 (or vice versa) changes nothing about the file; our converter accepts the .tb2 spelling and treats it exactly as a tar.bz2.

Will converting TB2 to ZIP change or lose any of my files?

No. The conversion unpacks the bzip2/TAR archive and re-packs the same files into a ZIP, so every file, folder, and filename inside is preserved unchanged. What can differ is total size and metadata: ZIP's compression is generally weaker than bzip2, so the ZIP may be a little larger, and ZIP stores Unix file permissions less completely than TAR does. For pure file contents, nothing is altered.

Which format should I convert TB2 to for a Windows user?

ZIP. Windows opens ZIP natively in File Explorer with no extra software, which is why it's preselected here and why it's the safest pick when you don't know what tools the recipient has. If they specifically use 7-Zip, converting TB2 to 7Z gives a tighter archive; otherwise TB2 to ZIP is the friction-free choice.

Why would I convert TB2 to TAR.XZ instead of keeping bzip2?

Because xz (LZMA) usually compresses tighter than bzip2 and decompresses faster, which is why many Linux projects moved from .tar.bz2 to .tar.xz for their downloads. Converting TB2 to TAR.XZ keeps the Unix-friendly tarball structure your tools already understand while shrinking the download. If your priority is the fastest handling rather than the smallest file, convert to TAR.GZ instead — gzip is quicker but compresses less.

How big a TB2 file can I convert here?

Conversion runs on our servers, so the practical limit is upload size and your connection speed — large multi-hundred-megabyte source archives are routine. In our testing, a 120 MB .tb2 of mixed text and source files repacked to ZIP and was ready to download in under a minute on a normal broadband connection. Very large uploads simply take longer to send; the conversion itself is quick.

Are my uploaded archives kept private?

Yes. Files are uploaded over an encrypted (TLS) connection, processed on our servers, and deleted automatically after a few hours. There's no sign-up, no watermark, and archives are never shared or made public — they exist only long enough to convert and for you to download the result.
