GPS Overlay Toolkit is a lightweight, browser-based suite of tools for working with GPX files and converting them into video-friendly overlays. Built for mountain biking and action sports, the toolkit is especially helpful for creators using DaVinci Resolve to visualize real-time GPS movement on screen.

• Converts .gpx files to:
  • SVG route overlays
  • SPL timing files compatible with DaVinci Resolve
• Customize:
  • Path color, thickness, drop shadow, and offset
  • Frame rate
• Real-time preview before download

• Visually trims the start and end of a GPX track
• Live map preview using Leaflet
• Export the cleaned .gpx file
