Turn a GPX File Into a 3D Route Video

TrailReplay is a free, open-source studio for runners, cyclists, hikers, and outdoor creators. Import a GPX or KML track, replay it on a 3D map with terrain, and export the animation as a video with distance, pace, elevation, photos, and annotations.

Routes are parsed locally in your browser — no account, no upload, and no installation.

How it works

  1. 1. Import one or more GPX or KML files, or combine them into a longer journey.
  2. 2. Choose the basemap, 3D terrain, camera behaviour, and trail style.
  3. 3. Add live statistics, elevation, photos, icons, and text annotations.
  4. 4. Record an MP4 or WebM in landscape, square, or vertical format.
