What is NMEA?
NMEA is the raw text protocol GPS receivers and loggers output, one sentence per position fix.
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 NMEA to GPX?
Raw NMEA logs from a GPS receiver or logger are not usable in maps. Convert the NMEA sentences into a clean GPX track.
How to convert NMEA to GPX
1. Drop your NMEA 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.
Which files does it accept?
NMEA logs as .nmea, .log or .txt containing standard GPS sentences.
