TBZ2 Converter
FileFlip converts TBZ2 files into 10 other formats entirely inside your browser, using libarchive compiled to WebAssembly. The TBZ2 file is never uploaded to a server: it is read off your disk, converted on your own machine, and saved back by the browser. There is no file-size limit and no account to create.
How do I convert a TBZ2 file?#
- Drop your TBZ2 file onto the converter at the top of this page, or click it to pick one from your computer.
- Choose the format you want out of it. FileFlip downloads the engine that conversion needs, once, and your browser caches it.
- Conversion starts the moment you pick the format, and the result is yours to download. The work happens in this tab, so nothing is uploaded and nothing is queued.
Is it safe to convert TBZ2 files online?#
Yes, because nothing is uploaded. FileFlip converts TBZ2 files inside the browser tab you already have open, using WebAssembly builds of the same engines a desktop converter would install. Your file is read from your own disk into the page's memory, and no request carrying it is ever made.
You do not have to take that on trust. Open your browser's network panel, run a conversion, and you will see the engine come down and your file go nowhere. There is no upload, no server-side copy, no retention window, and no account tied to what you converted.
How FileFlip works lists every engine, its version and its download size, and shows how to check for yourself that nothing leaves your machine.

What is a TBZ2 file?#
A TBZ2 file is a TAR archive compressed as one continuous bzip2 stream under a single extension, so unlike ZIP, extracting one file means decompressing everything that comes before it in the archive.
Use TBZ2 when a tarball needs to be smaller than TGZ makes it and the slower compression time is acceptable.
Convert TBZ2 to TXZ for a smaller result still, or to TGZ when speed matters more than size.
The TBZ2 file format reference covers the specification, the programs that open one, and what each conversion keeps or drops.
TBZ2 questions people ask#
What's the difference between .tar.bz2 and .tbz2?
Nothing; TBZ2 is a tar archive compressed with bzip2, identical in content to a file named .tar.bz2, with tbz2 just the shortened single-extension spelling.
Is a TBZ2 smaller than a TGZ of the same files?
Usually yes. bzip2 typically compresses tighter than gzip, so a TBZ2 archive of the same directory is often smaller than the equivalent TGZ, at the cost of taking longer to create.
Why would I pick TBZ2 over TXZ?
TBZ2 compresses faster than TXZ for a similar amount of size reduction, since bzip2's block-based compression is lighter on CPU than xz's LZMA2. If squeezing out the smallest possible file matters more than compression time, TXZ usually wins instead.
