Step by step
How to convert GPX to GML
- 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 GML as the output
Pick GML, reproject to any of 180+ coordinate systems if needed, trim attributes and preview the geometry on a map.
- 03
Download the .gml file
Save a single file, or convert a whole batch and download everything as a ZIP. Nothing is stored after the download.
GPX to GML — questions
Is converting GPX to GML 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 GML?
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?
Reader handles simple feature members; complex schemas may need a desktop GIS. You can also reproject between 180+ coordinate reference systems or add a custom proj4 definition before writing.
