About Converting KML to GPX

KML is the XML format Google Earth introduced for describing points, paths, polygons and overlays on a map. It became an Open Geospatial Consortium standard in 2008 and is now read by most mapping software. When you need to move away from KML, the usual reason is simple: verbose — large datasets produce very big files.

Converting your KML map file to GPX solves that. GPX is the open XML schema that GPS devices and fitness apps use to record where you went. It holds three distinct things: waypoints, routes you planned, and tracks you actually travelled, usually with a timestamp and elevation on every point. In practice you gain universal on gps units, watches and fitness platforms and preserves timestamps and elevation per point. PrivConvert runs the whole KML-to-GPX conversion in server memory and deletes your file the instant the GPX is ready — nothing is stored, logged or reused.

When this conversion helps

  • You need universal on GPS units, watches and fitness platforms
  • You need preserves timestamps and elevation per point
  • You need simple, well-documented open schema
  • Sharing a KML map file with someone whose software expects GPX

Tips for best results

  • After converting, open the GPX and skim the formatting — complex layouts occasionally need a small touch-up.
  • Files up to 250 MB are supported, and you can batch-convert several KML files at once; each is processed privately and deleted immediately.

How to Convert KML to GPX Online

Here is how a KML → GPX conversion works on PrivConvert, from start to finish. What you gain with GPX: universal on GPS units, watches and fitness platforms.

1
Upload your KML file

Drag and drop your file into the upload area, click to browse your device, or paste a URL to a file hosted online. You can upload files up to 250 MB and batch convert up to 20 files at once.

2
Automatic conversion

Once uploaded, the conversion from KML to GPX starts automatically. The process runs entirely in an isolated environment - your data never leaves the secure pipeline.

3
Download your GPX file

Your converted file is ready instantly. Click the download button to save it to your device. The file is deleted from memory immediately after download.

Private by design, not as an afterthought

Most online converters upload your files to a server, keep them for days, and may mine them for AI training or resale. PrivConvert was built the opposite way — around your privacy.

Works on any device

Runs in any modern browser on Windows, macOS, Linux, Android and iOS — no install, plugin or desktop software needed.

Fast in-memory processing

Each job runs in an isolated in-memory sandbox, so most conversions finish in seconds instead of waiting in a queue.

Nothing is stored

We never keep a copy. Once your GPX is delivered, both the original and the result are gone — there is nothing left to leak or misuse.

Isolated sandbox

Every conversion runs in its own locked-down process with no network access, so files can never leak or interfere with one another.

Frequently Asked Questions

How do I convert KML to GPX?
Upload your .kml file and complete the quick security check. Point placemarks become waypoints and lines become tracks, then the GPX downloads in seconds ready for your GPS device.
How are KML shapes mapped to GPX?
Point placemarks become GPX waypoints and LineStrings become tracks. Because GPX has no area type, a KML Polygon is exported as a track following its outer ring; KML styles and icons are not carried over.
Does it handle folders and multi-geometry?
Yes. Placemarks nested inside Document and Folder elements are all collected, and MultiGeometry placemarks are expanded into their individual points and lines.
Is my data safe and private?
Yes. The file is parsed entirely in server memory with a hardened, XXE-safe XML parser, never written to disk, never stored or logged, and deleted the moment your download is ready.
