GPX to XZ Converter
Processing entirely on your device — large files may take a moment.
Unpack XZ into ZIP/TAR for tools that cannot read LZMA2. If your files are still in GPX format, this page is the shortcut: GPX is the GPS track format: waypoints, routes and recorded tracks with timestamps, written by every watch, phone and bike computer.
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 GPX format
GPX is the GPS exchange format: an XML file with waypoints, routes and — most importantly — <trk> tracks of timestamped coordinates. Every sports watch, phone app and bike computer exports it, which makes it the common denominator of “where have I been” data.
Converting GPX to GeoJSON puts the track on an interactive map; converting to CSV turns it into rows you can pivot, chart or join with sensor data.
+Strengths
- ✓Universal across GPS devices and apps
- ✓Timestamps enable pace and speed analysis
- ✓Simple XML, easy to post-process
!Limitations
- −No styling or basemap context
- −Large tracks make big files
About the XZ format
XZ wraps the LZMA2 algorithm: the best ratio of the common Unix compressors, which is why distribution packages and source releases pick it when bandwidth matters more than CPU.
Windows Explorer and many cross-platform tools cannot open it — unpacking to ZIP or TAR makes the payload portable.
+Strengths
- ✓Highest common ratio
- ✓Standard for Linux packages
- ✓Integrity checks built in
!Limitations
- −Memory-hungry at high settings
- −Sparse support outside Linux
Why convert GPX to XZ?
There is a concrete reason this conversion exists: No styling or basemap context XZ sidesteps that — Highest common ratio If that is your situation, the tool above settles it in seconds, entirely on your device.
Frequently asked questions
Is this GPX to XZ 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 GPX to XZ?
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.
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 GPX file.
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.
