Why this tool is useful
Prepare a private GPS export for local GIS analysis, offline visualization or a controlled data pipeline without granting a third-party converter access to movements.

Private GPX to GeoJSON Converter
Convert GPX tracks, routes and waypoints into a standards-friendly GeoJSON FeatureCollection with names, timestamps, elevation and inert link metadata while excluding invalid coordinates.
Ready. Your working data stays in this browser.
Files and capture streams stay on this device. Processing uses browser APIs only; nothing is uploaded to YTSave, the media API or a proxy. No server copy is created, stored or left to delete. The file picker is cleared when processing starts, and disposable worker memory is destroyed after completion or cancellation. Preview and generated-output memory is released when you clear the tool or leave the page.
How it works
Valid track segments and routes become LineString features and valid waypoints become Point features; source links remain plain properties and are never opened.
Practical example
Convert a walking GPX file to GeoJSON, inspect its feature names and coordinate arrays, then load the downloaded result into a desktop GIS project.
Validation
The calculation is deterministic and explains validation errors instead of silently changing invalid input.
Privacy boundary
Input and output remain in this tab. Copy and download happen through browser APIs without a server upload.
Result passport
Every run reports its tool mode, timestamp and input/output size so transformed data can be audited.
