About GPX Analyzer
Free GPS tools built by one developer who actually uses them on the trail.
Why this site exists
GPX Analyzer is an independent, one-developer project: seven free browser-based tools for working with GPX files and GPS coordinates, plus practical guides on GPS file formats and offroad navigation. Everything here grew out of the same problem — needing simple, reliable ways to inspect, repair, and convert GPS data before heading somewhere without cell service.
The site is built and maintained by the developer behind the GPS iOS apps MyGPSConverter, MyGPSLog, MyGPSWaypoints, and RC Sentinel. The browser tools share the same conversion and analysis logic the apps use in the field, so what you see on a tool page here reflects how the apps handle real GPS data on real trips — desert two-track, backcountry trails, and offroad rally stages.
Privacy is the feature
Every tool on gpxanalyzer.com runs entirely in your browser. Your GPX, KML, and CSV files are parsed locally on your device — nothing is uploaded to a server, ever. There are no accounts, no paywalls, and no feature gates. The iOS apps follow the same principle: data stays on your device unless you choose to export it.
That isn't a marketing line; it's an architecture decision. GPS tracks reveal where you live, park, camp, and travel. Tools that handle them shouldn't require you to hand that data over.
Found something wrong?
The guides aim to be technically accurate — datums, elevation models, GPX schema details, and format quirks included. If you spot an error in a guide or a bug in a tool, send a note. Fixes ship fast.
