XBM to TBZ2 Converter
Processing entirely on your device — large files may take a moment.
Convert TBZ2 exactly like TAR.BZ2. If your files are still in XBM format, this page is the shortcut: XBM is a bitmap stored as C source code — literally an array of hex bytes that a C compiler includes. It was the original X11 icon format, and it still compiles.
This converter runs entirely in your browser using WebAssembly — your files never leave your device, nothing is uploaded, and there are no watermarks, sign-ups or queues. Drop in several files at once to convert them as a batch.

About the XBM format
XBM is the most honest image format ever shipped: the "file" is a C source array of hex bytes, compiled straight into X11 applications as cursor and icon bitmaps. Rendered, it is 1-bit black and white — the ancestors of every pixel-art cursor you still use.
Because it compiles, XBM never died: firmware UIs, embedded icons and retro Unix tooling still want it. Converting a PNG down to XBM gives embeddable, compilable art; the other direction previews what the C array actually draws.
+Strengths
- ✓Compiles directly into C/C++ programs
- ✓Zero-payload format — text only
- ✓Still required by embedded and Unix tooling
!Limitations
- −1-bit black & white only
- −Human-hostile representation
- −X11 bit order trips up hand-rolled decoders
About the TBZ2 format
TAR.BZ2 pairs the tar container with bzip2 compression — the classic release artifact of the 2000s Unix world. Bzip2's block-sorting algorithm compresses text and source trees noticeably tighter than gzip, which is why distribution mirrors and source releases favoured it for years.
Today it has largely ceded the top spot to TAR.XZ (smaller) and tar.gz (faster), but countless build scripts, mirrors and legacy toolchains still expect the exact .tar.bz2 artifact — and producing it is a matter of running the tar through a bzip2 encoder.
+Strengths
- ✓Tighter than gzip on text and source trees
- ✓Classic, universally supported on Unix-like systems
- ✓Deterministic, well-understood artifact for releases
!Limitations
- −Slow compression compared to gzip/zstd
- −Larger than TAR.XZ for the same content
- −Single stream — no random file access
Why convert XBM to TBZ2?
Think of it as moving your file to the container that fits the job. 1-bit black & white only TBZ2 works differently: Tighter than gzip on text and source trees If any of that sounds like your task, run the conversion — it takes seconds and nothing leaves your device.
Frequently asked questions
Is this XBM to TBZ2 converter really free?
Yes — completely free, with no sign-up, no watermark and no daily conversion limits. The site is supported by advertising.
Are my files uploaded to a server?
No. The conversion runs entirely inside your browser using WebAssembly, so your files never leave your device — that is what makes it instant and private.
Does it work on Windows, Mac, iPhone and Android?
Yes. Anything with a modern browser works: Windows, macOS, Linux, Android and iOS. No software installation is required.
Will I lose quality converting XBM to TBZ2?
No — TBZ2 is a lossless format, so every pixel of the converted image matches your original XBM file. You can also adjust the quality/size balance before converting when the target format supports compression.
Can I convert several XBM files at once?
Yes — drop as many files as you like into the tool and they are converted in one batch. When more than one file comes out, everything is bundled into a ZIP for a single download.
Will transparent areas survive the conversion to TBZ2?
Transparency is kept whenever TBZ2 actually supports an alpha channel. If the target format has none (like JPG), transparent areas are flattened onto a white background — that is a property of the format, not of this tool.
