KML to BZ2 Converter
Processing entirely on your device — large files may take a moment.
Convert BZ2 to ZIP or TAR when modern tools need a friendlier container. If your files are still in KML format, this page is the shortcut: KML is Google Earth’s XML markup for places, paths and polygons — still the lingua franca of consumer map sharing.
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 KML format
KML (Keyhole Markup Language) started life as Google Earth’s file format and became an OGC standard. It describes placemarks, paths, polygons and even camera tours, with rich styling — which is also why it is heavier and harder to parse than GeoJSON.
Most KML files in the wild come from Google Earth exports and government portals. Converting them to GeoJSON puts the same places into any web map without a Google Earth dependency.
+Strengths
- ✓Rich styling, tours and descriptions
- ✓Google Earth and Maps read it natively
- ✓OGC standard, widely published by agencies
!Limitations
- −Verbose XML, hard to hand-edit
- −Web map libraries need conversion first
About the BZ2 format
BZ2 applies the Burrows–Wheeler transform: slower than gzip but noticeably smaller, which is why Wikipedia database dumps and old source tarballs still arrive as .bz2.
Few GUI tools ship a bz2 reader these days, so converting the contents into a ZIP or TAR is the practical way to hand the payload to someone else.
+Strengths
- ✓Better ratio than gzip
- ✓Common in dumps and archives
- ✓Mature, stable format
!Limitations
- −Slow to compress and decompress
- −Declining tool support
Why convert KML to BZ2?
There is a concrete reason this conversion exists: Verbose XML, hard to hand-edit BZ2 sidesteps that — Better ratio than gzip If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this KML to BZ2 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.
Is there a file size limit for KML to BZ2?
The only limit is your device's memory, since nothing is uploaded. Files up to a few hundred megabytes work fine on a modern desktop browser; very large files simply take a little longer.
Is there a size limit for archive conversion?
There is no upload cap because nothing is uploaded — the practical limit is your device memory. A few hundred megabytes of unpacked content works comfortably on a modern computer.
What about folders and directory structure?
The full directory tree is preserved: folders stay folders, and deep paths arrive exactly as they were packed in the KML file.
