What is KMZ?
KMZ is a zipped KML — the compact single-file version used by Google Earth, smaller to share and store.
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.
Why convert KMZ to GPX?
You have a KMZ from Google Earth but need GPX for a watch, hiking portal or editor. This unzips the KMZ and writes a clean GPX track.
How to convert KMZ to GPX
1. Drop your KMZ file above (or click to choose). 2. It is converted on the spot. 3. Your GPX 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.
What is the difference from KML to GPX?
KMZ is just a zipped KML — this page accepts the zipped file directly, no need to unzip first.
