Step by step
How to convert GPX to KML
- 01
Drop your .gpx file
Open the converter and drop the GPX file — parsing happens locally in a Web Worker, so nothing is uploaded.
- 02
Choose KML as the output
Pick KML, reproject to any of 180+ coordinate systems if needed, trim attributes and preview the geometry on a map.
- 03
Download the .kml file
Save a single file, or convert a whole batch and download everything as a ZIP. Nothing is stored after the download.
GPX to KML — questions
Is converting GPX to KML really private?
Yes. The conversion runs entirely in your browser using a Web Worker — the GPX file is never sent to a server, so it works with confidential data and offline.
Do I need an account to convert GPX to KML?
No. There is no signup, no email and no install. Open the converter, drop the file and download the result.
What happens to attributes and coordinate systems?
KML is always written in EPSG:4326, as required by the specification. You can also reproject between 180+ coordinate reference systems or add a custom proj4 definition before writing.
