Visualise Your GPS Tracks on an Interactive Map
GPS-enabled devices — from dedicated Garmin handhelds to smartphones and sports watches — constantly record your position, elevation, and time as you move through the world. This data is typically exported as a GPX file, a lightweight XML format that has become the universal language of GPS data exchange. But raw GPX files are just text: a dense list of coordinates and numbers that tell you very little until visualised on a map. A dedicated gps file viewer turns that raw text into something you can actually read at a glance.
This gpx viewer online transforms those coordinates into an interactive picture of your journey. Open gpx file data and within seconds your route appears as a green polyline over an interactive map, the elevation profile fills in below, and your track statistics populate in the sidebar. No account creation, no file upload to a server, no waiting — the entire process runs inside your browser using native browser APIs. Your GPS data stays on your device.
Watch: GPX File Viewer in Under a Minute
Prefer to watch instead of read? This short walkthrough covers uploading a GPX track, viewing it on the map, and reading its elevation profile.
Step-by-Step Guide
Step 1
Tool Opens with Empty World Map
The GPX File Viewer loads showing an empty world map and the sidebar on the right. The sidebar contains an upload zone, track statistics panel, basemap selector, and action buttons. The elevation profile panel sits below the map.
Step 2
File Drop Zone Ready to Accept GPX
The dashed drop zone in the sidebar highlights green when you drag a GPX file over it. You can also click anywhere on the zone to open the system file browser and select a .gpx file from your device.
Step 3
GPX Track Drawn on Map
After opening a file, the GPS track appears as a green polyline on the map. The sidebar immediately populates with track statistics: total distance, elevation gain, elevation loss, max/min elevation, duration, and point count.
Step 4
Map Zooms to Track Extent
The map automatically fits the view to show the entire track with padding. You can also click "⊙ Zoom to Track" in the sidebar at any time to return to this view, useful after panning away to explore the surrounding area.
Step 5
Click Start or End Marker for Popup
The green circle marks the track start and the red circle marks the finish. Clicking either marker opens a popup showing the elevation at that point and the timestamp if it is embedded in the GPX file.
Step 6
Topo Basemap Active Showing Terrain
Switching to the Topo basemap reveals contour lines and terrain shading, making it easy to understand the landscape context of your GPS track. Useful for hiking and mountaineering routes where terrain matters.
Step 7
Satellite Basemap with Track Overlay
The Satellite basemap shows aerial and satellite imagery from Esri's World Imagery service. The green GPX track overlays clearly over the aerial photo, letting you see the exact path relative to real-world terrain features, trails, and roads.
Step 8
Elevation Profile with Hover Tooltip
The elevation profile chart at the bottom of the tool shows the terrain shape of your entire track. Moving your mouse over the chart displays a dashed vertical line, a dot on the profile, and a tooltip showing the exact distance and elevation at that point.
Step 9
Dark Basemap with Green Track
The Dark basemap provides a high-contrast background that makes the green GPS track stand out vividly. This is particularly useful for screenshots, presentations, and social media sharing of your route.
Step 10
Waypoints Shown on Map with Popup
Named waypoints embedded in the GPX file appear as blue circle markers. Clicking a waypoint opens a popup showing its name, description, and elevation if available. Waypoints are commonly used for campsites, summits, checkpoints, or points of interest along a route.

Frequently Asked Questions
What does the elevation profile chart show?
The elevation profile shows how your altitude changes over the course of your track. The horizontal axis represents cumulative distance from the start in kilometres, and the vertical axis shows elevation above sea level in metres. The green filled area lets you see the terrain shape at a glance — climbs appear as rises, descents as drops, and flat sections as plateaus. Hover over any point to see the exact distance from the start and the elevation at that location. If your GPX file does not contain elevation data, the profile will show a flat line.
Can the viewer display GPX waypoints and routes?
Yes. This viewer supports all three GPX data types: tracks (trk/trkpt), routes (rte/rtept), and waypoints (wpt). Routes are treated as tracks and drawn as green polylines. Waypoints appear as blue circle markers — click any to see its name, description, and elevation. If your GPX file contains multiple track segments (trkseg elements), each is drawn as a separate polyline — useful for multi-day journeys exported as a single file with gaps between days.
What is a good GPX viewer for Google Maps?
Google Maps does not natively support GPX import. Google My Maps (mymaps.google.com) lets you import a GPX file as a map layer — it supports up to 2,000 points and multiple layers. You can also convert GPX to KML and drag it onto Google Earth. However, Google My Maps provides no elevation profiles or statistics. This tool gives you instant elevation profile, distance, elevation gain/loss, and interactive basemap switching — all in the browser with no account required.
What is the difference between elevation gain and elevation loss?
Elevation gain is the total accumulated ascent — the sum of all uphill portions of your track. Elevation loss is the total accumulated descent — the sum of all downhill portions. For an out-and-back route, gain and loss are usually approximately equal. This tool uses a 0.1 m threshold when counting elevation changes to filter out GPS noise — without this, small random fluctuations in GPS altitude readings would artificially inflate both figures, which is a common problem with phone GPS that lacks a barometric altimeter.
How do I fix a GPX file that won't load?
GPX load failures are usually caused by four issues. First, the file may not be valid XML — open it in a text editor and check it starts with an XML declaration and has a GPX root element. Special characters in waypoint names must be XML-escaped. Second, your file may be TCX or FIT format, not GPX. Third, the file may be truncated — re-export or re-download it. Fourth, some apps add a Byte Order Mark (BOM) that can confuse parsers. You can validate GPX files at gpx.studio or the official Garmin GPX Validator.
Which basemap should I use for hiking vs cycling?
For hiking and trail running, the Topo basemap is best — it shows contour lines and elevation shading that reveal the terrain shape, identifying ridge lines, valleys, and steep sections. For road cycling, the Street basemap gives clean road detail. For mountain biking, Topo or Satellite work best — Satellite shows the actual surface of trails. The Dark basemap creates high-contrast screenshots where the green GPS track stands out vividly and works for any activity type.
How do I export a GPX file from my GPS device or app?
On Strava, open an activity, click the three-dot menu, and select Export GPX. On Garmin Connect, open an activity and use the gear icon then Export to GPX. On AllTrails, activities you have recorded can be exported from the activity page. On Komoot, go to a tour and click the download icon. For Garmin GPS devices, connect via USB and copy .gpx files from the Activities folder. On iPhone, WorkOutDoors, Footpath, and Gaia GPS support direct GPX export. On Android, OsmAnd, Maps.me, and Locus Map all export GPX natively. Not all apps that open gpx files also let you export them, so check your app's sharing or export menu first.
How is total distance calculated — is it accurate?
Total distance is computed using the Haversine formula, which calculates the great-circle distance between consecutive GPS track points. This is the same method used by most GPS apps. Accuracy depends on your recording interval — a track recorded every second will be very accurate, while one recorded every 60 seconds may underestimate distance on winding paths by cutting corners between widely spaced points. This tool calculates 2D horizontal distance, so on very steep terrain the result may be slightly less than what your GPS device showed.
What is a GPX file and what information does it contain?
GPX (GPS Exchange Format) is an open XML-based standard for storing GPS data. A GPX file can contain three types of data: tracks (trk elements), routes (rte elements), and waypoints (wpt elements). Tracks are sequences of timestamped geographic coordinates recorded by a GPS device as you move. Each track point stores latitude, longitude, elevation, and optionally a timestamp. GPX files are the standard export format for Garmin, Suunto, Wahoo, Strava, Komoot, and AllTrails.
Is my GPX data sent to a server?
No. Your GPX file is opened and processed entirely within your browser using the browser's built-in FileReader and DOMParser APIs. The file bytes never leave your device — there is no upload to our servers, no cloud processing, and no storage of your track data. Map tiles fetched from CARTO, OpenTopoMap, and Esri contain only tile coordinates, not any of your GPS data. This makes the tool safe to use with sensitive tracks, private property routes, or any GPS data you prefer not to share. It is a genuinely private way to view gpx file online without any server round-trip.
Understanding the Elevation Profile — Using This Tool as a GPX Elevation Viewer
The gpx elevation profile chart at the bottom of the tool is one of the most useful features for any outdoor activity. It shows altitude (Y axis, in metres above sea level) against cumulative distance from the start (X axis, in kilometres). The shape of the profile immediately communicates the difficulty of the terrain: a sawtooth pattern indicates repeated steep climbs and descents, a smooth arc shows a single long climb followed by a descent, and a flat line indicates a route with little vertical variation.
GPX elevation gain and elevation loss are displayed separately because they tell different stories. A 1,000 m elevation gain route is significantly harder than a 200 m gain route of the same distance. The 0.1 m threshold used when counting gain and loss filters out GPS noise — without this, random altitude fluctuations from the GPS signal would artificially inflate both figures, sometimes adding hundreds of phantom metres to a flat run. Hover over any part of the profile chart to see the exact elevation and distance at that point.

What Can a Good App to Open GPX File Data Show You?
A typical GPX file exported from a sports watch or dedicated GPS unit contains rich data beyond simple coordinates — this gpx reader online surfaces all of it:
- Track line — the full path of your route drawn as a continuous line on the map, showing every turn, switchback, and detour you took.
- Waypoints — named points of interest embedded in the file, shown as blue markers on the map. Common uses include summits, water sources, campsites, road crossings, and emergency evacuation points.
- Elevation data — the altitude above sea level at each recorded GPS point, used to build the elevation profile and compute gain/loss statistics.
- Timestamps — the exact date and time of each track point, from which the viewer calculates total duration and (if needed) speed at any point.
- Track name — a human-readable name embedded in the GPX metadata or first track element, displayed in popups and used to identify multi-track files.
