GPX Viewer & Editor

Open a GPX file on a map, check the speed and altitude, and edit the track. The file stays on your device.

  • GPX viewer online
  • Edit the track
  • GPX to CSV

This GPX viewer reads a track, a route, or waypoints. After it loads, the map fills the page. Speed, altitude, distance, and time sit under the map. Trim, simplify, reverse, or fix elevation spikes, then download GPX, CSV, or KML.

Open a GPX file

Your file never leaves your device.

How it works

  1. 1

    Open the file

    Drop a .gpx file, or choose one. A track from a watch, a phone, a logger, or a camera export all open the same way.

  2. 2

    Read it here

    The browser draws the path and the graphs. That read stays on your device. Nothing is sent to a server.

  3. 3

    Edit or export

    Trim the ends, thin a dense line, reverse it, or fix a bad elevation spike. The map shows the change before you keep it. Save GPX, a CSV for a spreadsheet, or KML.

Drop the file and the route fills the map. Start and end are marked. Open Graphs for speed, altitude, distance, and time. If the file has several tracks, each one is listed and the map shows the one you pick.

Waypoints stay as points on the map. They are not joined into a line. A route with no track is drawn as the line you can edit.

What you can edit

  • Trim keeps the points between two handles on one bar. The bright line on the map is the part you keep.
  • Simplify drops points that sit close to a straight line. Drag the distance and the map shows the points that would remain.
  • Reverse flips the direction. The timestamps still run forward, so the graphs stay readable.
  • Fix elevation replaces isolated spikes and fills short gaps from nearby points in the file. It does not download new heights.

Undo puts the last edit back. The original file on your device is left as it was until you download a new one.

GPX to CSV, or back to GPX and KML

Export writes a file on this device. GPX is the track you are viewing. If the file already has several tracks, the GPX download keeps every part. CSV is one row per point: time, latitude, longitude, altitude in metres, and speed in metres per second. KML is the line for an earth-style map.

Privacy

Your file never leaves your device. There is no upload and no account. Closing the tab drops the track from this page.

Questions

Does the GPX file get uploaded?

No. The browser reads the file where it already is. GPS Toolset does not receive a copy.

What is a GPX file?

GPX is a common file for a GPS track: a list of positions, often with time and elevation. Watches, phones, loggers, and some cameras can save one. This page opens it on a map.

What can I change in the track?

You can trim a start and end on one bar, simplify a dense line, reverse the direction, and fix elevation spikes using nearby points in the file. Trim and simplify show the result on the map before you keep it. Undo puts the last edit back. Download when you want a copy.

Can I turn a GPX file into a CSV?

Yes. After the track loads, Export can save GPX, CSV, or KML. CSV is one row per point, with time, latitude, longitude, altitude in metres, and speed in metres per second. The file is saved on your device.

What does fix elevation do?

It replaces isolated spikes and fills short gaps from the elevations already in the file. It does not download new heights, and it does not send your track anywhere.

The file has several tracks. Which one do I edit?

Each part is listed under Edit. The map shows the part you pick. A GPX download keeps every part. CSV and KML save the part you are viewing.

Will this work on a phone?

Yes. Choose a .gpx file from your phone. The map fills the screen, and the edit controls are large enough to tap.

A video from a GoPro camera that recorded GPS can be read on the GoPro GPS extractor, then opened here if you download the GPX. Other converters will sit with these tools.
