About This GPX Cleaner

Clean GPX Elevation Online is built for runners, hikers, cyclists, and mappers who expect precise elevation data without the bloat that clutters most GPX editors. The tool opens instantly in your browser, keeps every change on-device, and intelligently smooths noisy altitude spikes using adaptive windowing plus grade-aware outlier detection. Four quick presets—Trail, Road, Commute, and Aggressive—dial in the perfect configuration instantly, so you skip the guesswork competitors force on you.

Beyond basic editing, you can enrich tracks with new points, adjust coordinates with sub-meter precision, and export both refreshed GPX and analysis-ready CSV reports. A real-time elevation profile offers immediate feedback, helping you validate every adjustment before you hit download, while clipboard-ready summaries make sharing painless.

Unlike heavyweight desktop apps, the interface prioritizes clarity, keyboard-first accessibility, and lightning performance. Whether you want to repair barometer drift, merge data from multiple devices, or prep a route for sharing, this toolkit balances professional control with approachable design. No logins, no ads, just fast cleanup.

How to Use

  1. Upload a GPX file or paste raw XML directly into the editor, then click Parse & Visualize.
  2. Review the summary tiles for total distance, ascent, descent, elevation range, and data confidence.
  3. Tap a preset (Trail, Road, Commute, or Aggressive) or fine-tune the smoothing window, spike sensitivity, and grade limit till the live profile looks right, then hit Clean elevation.
  4. Edit any row inline, add new coordinates with timestamps, or remove noisy points instantly.
  5. Download the refreshed GPX, export the elevation table to CSV, or copy a shareable summary to your clipboard.

Pro tip: tap the sample dataset to test-drive the workflow before loading your own route.

Tips for Better GPX Data

  • Start with the Trail preset for technical routes, then tweak the window size by one point at a time for razor-thin ridgelines.
  • Use the grade limiter to catch sudden elevation jumps that are physically impossible for your activity type.
  • Trim redundant points at pauses or turnarounds to reduce file size and improve device battery life when navigating.
  • Export the CSV profile and compare it against weather or heart-rate data for deeper ride or hike analysis.
