GPX Validator
Validate your GPS Exchange Format files. Check for errors, warnings, and data quality issues. Free and private — files are processed in your browser.
What we check
- Valid XML structure
- Required elements and schema compliance
- Coordinate bounds and validity
- Missing or empty feature names
- Duplicate coordinates
- Data quality suggestions
Common issues we detect
Malformed XML structure from manual editing, coordinates outside valid ranges (latitude ±90°, longitude ±180°), missing required elements like track points or waypoint coordinates, empty track segments, duplicate consecutive coordinates, and missing timestamps that break route reconstruction in GPS devices.
When to validate your GPX
Before uploading to GPS devices to avoid transfer errors, after manual editing to catch XML mistakes, when routes won't load in apps like AllTrails or Strava, before sharing files publicly to ensure compatibility, or when combining multiple GPX files and want to verify the merged output maintains correct structure and data quality.
Frequently Asked Questions
What errors does the GPX validator check for?
The validator checks XML structure, required GPX elements, coordinate bounds (valid lat/lon ranges), duplicate coordinates, empty track points, missing names, and schema compliance. It also provides data quality suggestions like missing elevations or timestamps.
Is my GPX file uploaded to a server?
No. Validation happens entirely in your browser. Your GPX file stays on your device and is never sent to any server, ensuring complete privacy for your GPS data.
What's the maximum file size?
The browser-based validator can handle files up to 5MB. For larger files or batch validation, check out the full Takeout Tools app which supports files of any size.
Can I see my GPX data on a map?
Yes! The validator includes a map preview showing your tracks, waypoints, and routes. This helps you visually verify that your coordinate data is correct and complete.
