About GPXtoolset

GPXtoolset is a focused toolkit for your activity files. Convert GPX ↔ FIT, preview tracks, and prepare files for the tools you already use.

Privacy is built in. All conversion and processing run in your browser on your device. No accounts. No uploads. Your data stays with you.

Optional Strava import and upload use serverless endpoints only to handle OAuth and API calls. Files are never stored on our servers; they stay local to your session.

Fast, minimal, and distraction free. Get back outside sooner.

If the toolkit makes your day easier, I'd be thrilled if you bought me a coffee!
