YOUR TRACK WORKSHOP

Keep the journey.

Remove GPS drift at stops and simplify your route with precision.

Opened from Facebook or Instagram? If you can’t select files, use the app’s menu (⋯) and choose Open in browser to continue in Safari or Chrome.

GPX stays GPX, KML stays KML, and KMZ stays KMZ. Independent routes, folders and resources stay in their original files, including ZIP batches.

02 Processing settings

Remove stop drift

Stop radius 15 m

5 m50 m

Minimum stop duration 60 s

Keep the entry and exit points to preserve stop duration.

Simplify route

Deviation tolerance 3 m

Tolerance applies to simplification after stop cleanup.

Coordinate precision

Rounds latitude and longitude on export only. Elevation, timestamps, styles and folders stay unchanged. Preview shows the route before rounding.

03 Recording cleanup

Split at recording gaps

Minimum time gap 5 min Minimum distance gap 500 m

Split when both limits are reached between consecutive samples. No line connects the parts. Loose GPX exports use part 1, part 2, etc. ZIP archives keep original filenames with separate segments or geometries inside each file. Timestamps are required.

Trim after sustained high speed

Speed above 15 km/h Minimum fast travel 60 s Allow brief slowdowns 30 s

Find the first sustained fast section anywhere in each track, then remove everything after its start — including later stops or walking. At least two fast intervals are required. Detection resets at segment boundaries, invalid times and gaps at or above the time-gap limit. Review before exporting.

Your tracks stay yours.We do not and will not collect or store your tracks. All track processing happens locally in your browser; your files are never uploaded to our servers.Anonymous usage counts are sent to our counter; no tracks or filenames are included. Optional map tiles are loaded from OpenStreetMap for the area you view.
