Map to GPS is a browser tool for turning a line on a map into a file your GPS can follow. Click to plot. Drag to fix. Download a GPX track. There is no account.
The map uses OpenStreetMap data through OpenFreeMap. It covers roads, trails, waterways, and other mapped features worldwide.
The drawing tools here are not a routing engine: nothing snaps your line to a road or picks a path between two clicks. You place the points, check the line, and download the result. Two things can ask a public routing service to draw the road for you instead: the Google Maps import, which rebuilds the route a link carries, and the Follow the roads button, which takes the points you already drew.
