What is GPX?
GPX (GPS Exchange Format) is the universal, human-readable XML standard for GPS tracks — understood by almost every map, route planner, watch and hiking site.
What is KMZ?
KMZ is a zipped KML — the compact single-file version used by Google Earth, smaller to share and store.
Why convert GPX to KMZ?
KMZ is the compact, zipped KML that Google Earth prefers — smaller to email or store. Turn your GPX into a ready-to-open KMZ.
How to convert GPX to KMZ
1. Drop your GPX file above (or click to choose). 2. It is converted on the spot. 3. Your KMZ download starts automatically. No sign-up, and your file is never stored.
FAQ
What happens to my file?
Your file is sent to the Reisezoom server for processing, handled there and deleted immediately — nothing is stored. A browser cannot read FIT, TCX, KML or KMZ — some of those are packed binary formats. The conversion uses the same component as the desktop app.
Is it free, no sign-up?
Yes — completely free, no sign-up, and your file is never stored; it is only used to convert.
KMZ or KML?
KMZ is a zipped KML — same content, smaller file. Both open in Google Earth.
