About 🚴

gpx.studio is a free online GPX viewer and editor which allows to:
  • visualize multiple traces in different colors and aided by many different maps (cycling, hiking, satellite, etc)
  • edit traces by adding, inserting, moving or deleting track points
  • reverse traces
  • add or change the timestamps of a trace
  • view, add, edit and remove waypoints
  • reduce the number of track points
  • view and rework the structure of the file
  • automatically add elevation data to traces if missing
  • merge multiple traces, extending time, heart rate, cadence, power and temperature data where needed
  • extract segments from traces and perform any other action while maintaining the segments' structure within files
  • save the result on your computer or to your Google Drive™ to get a shareable link and embedding code
It is a one-person side project created after messing with GPX files for some time. The project source code is publicly available on GitHub. Follow us on Facebook and Twitter to be notified about updates of the tool.

Mapbox Community 🤝

Mapbox is the company providing some of the beautiful maps on this website. They created a program called Mapbox Community to support non-profits, educational institutions, and positive-impact organizations (see the official page where they showcase some of their collaborations). We are very lucky to have joined this program and to benefit from a great discount on all API rates.

I am (and all users of the website can be) very grateful for their support and availability.

Support 💬

The Help dialog and the User Guide should answer most questions about the functionalities, but feel free to ask for help, report any issues or send suggestions on the Facebook or Twitter page, or by email at hello@gpx.studio.

For developers, the Github repository is also a good place to report issues or share ideas.

Help keep the website free (and ad-free) 🙏

Each time you add or move a track point, we make a request to our servers to retrieve a route on the road network. We also rely on APIs from Mapbox to load beautiful maps, retrieve elevation data and process geocoding requests (looking for a place in the search bar).

Unfortunately this is very costly so if you like the tool and use it frequently, please consider making even a small donation so that this website can stay free to use and ad-free. Thanks for your support!

Translation 🗣️

The website is translated by volunteers on a collaborative translation platform. You can help complete and improve the translations by joining the Crowdin project. Get in touch on Facebook, Twitter, by email or on GitHub if you would like to start the translation in a new language. Apart from a good understanding of gpx.studio, some basic knowledge of HTML can be useful. Any help is greatly appreciated!

If you make a mistake or change your mind about the itinerary, use the undo and redo buttons.

If routing is enabled, select the appropriate activity type in order to take the most suitable roads. Disabling the routing will allow you to draw straight lines freely on the map.

If you edit a GPX file containing time, temperature, heartrate, cadence or power data, new track points will automatically contain the average value for each of those fields.
Crop a GPX file
There are three options:
  • Use the slider in the bottom panel to move the start and end points of the trace. Click on to validate the selection. You can choose whether you want to keep cropped parts in separate files.
  • Enter the edition mode by clicking on . Then, click on an anchor point or on the line and use Split here to split the trace at a chosen location.

Add timestamps to a GPX file
  1. Click on .
  2. Enter the average speed.
  3. Select the start time.
  4. Click on Ok.
If the GPX file has no timestamps, a constant speed is applied to the whole GPX file by default. You can check the box Experimental to generate timestamps which make the speed vary depending on the slope.
If the GPX file already has timestamps, they will be shifted and compressed to match the chosen speed and start time.
Change the date of a GPX file
  1. Click on .
  2. Change the start time.
  3. Click on Ok.
Change the speed of a GPX file
  1. Click on .

If the GPX file already has timestamps, they will be shifted and compressed to match the chosen speed and start time.
Merge multiple GPX files
To merge two GPX files:
  1. Below the bottom panel, select the tab of the first GPX file you want to merge.
  2. Click on (available only when more than two files are open).
  3. Click on the tab of the second GPX file to merge or an the trace itself. The track points of the second GPX file will come after those of the first GPX file.
You can also use the file structure tool:
  1. Below the bottom panel, select the tab of the first GPX file you want to merge.
  2. Click on .
  3. Drag the tab of the file you wish to merge into the first one and drop it in the file structure.

  2. Click on Export.
  3. Check the box Merge all traces.
  4. Click on Download to download the files on your computer or on Save to Google Drive to save it in the cloud.
When merging multiple GPX files: missing time, temperature, heartrate, cadence or power data will be automatically extended with the average value across merged files. If some GPX files contains timestamps, it is ensured that the timestamps of the merged file are strictly increasing (the timestamps of some files are shifted if necessary).
Extract tracks or tracks segments of a GPX file
To extract all tracks or tracks segments from a trace, click on (available only if the file has more than one track or track segment). If the GPX file contains waypoints (points of interest), they are kept in the files for which the traces pass closest.

To extract a specific track or track segment:
  1. Click on .
  2. Drag the track or track segment you wish to extract from the file structure to the tabs above the elevation profile.
Change the structure of a GPX file

Embedding 🗺

You are very welcome to display traces on your website with gpx.studio. There are two ways to do it: the first one with files stored on a server and the second one with Google Drive.
  • File URL: Add the link to the file in the urls attribute of the state parameter of the query string. Make sure to use https, to encode any special characters and that gpx.studio is allowed to request the files, otherwise the requests will be blocked by the CORS policy, i.e. you should set the following header in your server response:

    Access-Control-Allow-Origin: * or https://gpx.studio

  • Google Drive: Just save the files to your Google Drive when exporting and copy the code provided! If you want to display files that you already have on your Google Drive, add the ID of the file in the ids attribute of the state parameter of the query string and make sure they are available to all users with the link.

Choose the map shown by default with the parameter source among the following values:

  • outdoors: Mapbox Outdoors
  • satellite: Mapbox Satellite
  • osm: OpenStreetMap
  • otm: OpenTopoMap
  • ohm: OpenHikingMap

To use Mapbox maps, you need to specify the token parameter with a valid Mapbox token. You can also use a custom Mapbox style by directly specifying its URL with mapbox-style=<STYLE_URL>.

You can optionally add parameters to the source URL: imperial to get data in miles and feet, running to display the pace in minutes by unit of distance, distance to show distance markers, direction to show direction markers and slope to show the slope view of the elevation profile. Below is a playground to play with the parameters, see a preview and get the HTML code.
