Cut a track in two, merge multiple GPX files, fix elevation, reverse a route or plan one from scratch. Everything runs in your browser — no install, no account, your data never leaves your device.
Gravel cyclists, trail runners, long-distance hikers, kayakers — each tool answers a precise need, from creation to export.
Click the map to place waypoints. The routing engine calculates the best path for your chosen profile: road cycling, MTB, trail running or hiking. You can also draw freehand — useful for kayaking, stand-up paddleboarding or measuring the crossing distance across a lake or estuary. No starting file needed.
PlanningDrag and drop your file or click to select it. To convert FIT to GPX, import your Garmin file directly — no prior conversion needed. Compatible with Wahoo, Suunto, Bryton, Polar, Coros and Google Earth (KML). Import multiple files at once, with no limit on number.
ImportEnable Extend mode to continue a track from its endpoint — or from its start in reverse. Place additional points on the map with active routing: the new section connects cleanly to the original track. Useful for lengthening a recorded route or adding an out-and-back to a loop.
EditingOne click on the map or on the elevation profile places the cut marker. The track splits into two independent files you can edit and export separately. Useful for isolating a climb, separating two back-to-back recorded outings, or extracting a precise segment.
EditingAutomatically divide a track into fixed-length sections — for example every 10 km or every 30 minutes. Each section becomes an independent track. Ideal for preparing stages of a long-distance journey: split a Coast to Coast walk, an Alps cycling crossing or the West Highland Way over several days.
EditingSelect multiple GPX files and assemble them into a single route. Assembly order can be automatically optimised so that endpoints connect correctly. Ideal for reconstituting a route recorded in several outings — but also for preparing a multi-day journey: a 4-day hike along the Pembrokeshire Coast Path, a cycling tour of the Scottish Highlands or a long-distance trail walked over several sessions.
EditingImport multiple GPX files that cross or overlap. GPX Edit Pro analyses the intersections and generates up to 5 viable loops — each exportable as GPX. Ideal for creating an MTB loop from existing tracks, assembling trail paths or composing longer hiking circuits without retracing the same sections.
UniqueFlip the direction of a route in one click. You recorded the outward leg but want to navigate the return — reverse and export.
EditingOn a loop, choose where you want to begin without changing the rest of the track. Click the new start point — the route reorganises automatically. Locate a car park first using the POIs, then move the start point there.
EditingHandles are placed automatically every 500 m along your track. Drag a handle to redraw that section — routing recalculates in real time between neighbouring handles. More precise than moving individual points, faster than a full redraw.
EditingSwitch to edit mode to move, add or delete each GPS point individually on the map. Ideal for correcting an accidental detour, removing a zig-zag or adjusting an overly wide bend.
EditingThe Douglas-Peucker algorithm reduces the point count while preserving the general shape. Adjust the tolerance and see the result in real time before confirming. A 50,000-point GPX can drop to 3,000 with no visible distortion — essential for GPS devices with limited memory.
OptimisationYour GPS recorded erratic elevations due to poor signal? Recalculate from digital elevation models (EU-DEM, global SRTM). Elevation gain becomes reliable, graphs become coherent.
AnalysisCalculate positive and negative elevation gain, min/max altitude and gradient per segment. Hover over the curve to locate the corresponding point on the map. Select a zone on the profile to cut the track at exactly that point.
AnalysisColour your track by gradient: green for flat, orange for moderate slopes, red for steep sections. Spot the climbs at a glance before a cycling outing or identify the technical sections of a trail.
AnalysisThe track is coloured by actual surface: tarmac, compacted, gravel, dirt, grass, cobblestone, rock. A chart shows the percentage breakdown — essential before a gravel route so you know what to expect.
AnalysisCheck current conditions and a 7-day forecast for any point on your track: feels-like temperature, wind, rain probability, visibility. If your route climbs to a high point, a dedicated panel shows specific conditions at that altitude.
AnalysisOpen the comparison panel to view the statistics of each imported track side by side: distance, elevation gain, estimated duration, speed. Handy for choosing between two variants of the same route before you head out.
AnalysisDisplay mountain huts, passes, water fountains, car parks, restaurants, summits and other useful points near your route. Click a POI to automatically reroute your track to pass through it, then return to the main route.
PlanningDrop waypoints anywhere — a planned supply stop, a meeting point, a hazard to flag. Add a note to each marker. Waypoints are included in the GPX export as standard <wpt> tags.
Switch between several map backgrounds as needed: standard map, multiple topographic variants with contour lines. Useful for reading the terrain before a hike or analysing a col on a detailed topo map.
ComfortGenerate a print-ready A4 PDF for each track: topographic map capture, elevation profile, surface breakdown (tarmac, gravel, trail…), full statistics (distance, elevation gain, elevation loss, estimated duration). For multiple tracks, the export produces a ZIP containing a PDF and GPX per track. Choose the sport to adapt the layout (road cycling, MTB, trail, gravel, hiking).
ExportDownload your track in your preferred format. Standard GPX works with Garmin Connect, Wahoo, Suunto, Bryton, Polar, Coros, Strava, Komoot, RideWithGPS and the vast majority of GPS devices and sports platforms. KML for Google Earth. TCX for training platforms.
ExportGenerate a unique share link for any track. Your recipient opens it in their browser — the track displays on the map with elevation profile and statistics, no account or sign-up needed. A QR code is generated automatically, handy to print or display on screen. The GPX file remains downloadable from the link.
ShareChoose from 7 sport profiles — hiking, trail running, road cycling, gravel, MTB, kayak, stand-up paddleboarding — set your age, weight and effort level, and get a simulation with estimated duration, effective speed, heart rate and realistic cadence. Duration is calculated via the Naismith formula calibrated per sport. Useful for estimating the real time of a route before you go.
SimulationEnable your phone's GPS to locate yourself on the map and see your progress along the track. The compass shows your heading and the distance to the nearest track — handy during a recce or a navigation outing.
NavigationEvery change is recorded in a full history. A mis-placed cut, an accidental point move — undo in one click and your track is intact. Work without fear of losing your progress.
ComfortNo install, no account. Your GPX editor is ready in seconds.
Drag and drop a GPX, FIT, TCX or KML — or create a route from scratch directly on the map. Import multiple tracks simultaneously.
Interactive elevation profile, gradient visualisation, surface detection, 7-day weather, variant comparison — everything updates in real time.
Cut, merge, reverse, reshape, fix elevation, add POIs and waypoints — every operation can be undone.
GPX, KML, TCX, A4 PDF route book or share link with QR code — compatible with all GPS devices and sports platforms.
GPX Edit Pro reads files from your GPS devices and sports apps: Garmin, Wahoo, Suunto, Bryton, Polar, Apple Watch, Coros, Sigma and many others.
What you don't notice at first glance, but that makes a real difference from the second session onwards.
Choose the profile that matches your outing: road cycling, MTB, trail running or hiking. The engine calculates a realistic path on the appropriate network — not the same roads for a gravel rider and a cycle tourer.
Import tracks that cross each other. The algorithm builds a graph from intersections, eliminates dead-ends and proposes up to 5 viable loops from this path network.
Real surface detection in 7 categories (tarmac, gravel, dirt, grass, rock…) via PMTiles vector tiles. Breakdown displayed as a percentage along the track.
Elevation correction uses tiled topographic data: EU-DEM / Copernicus for Europe (25m resolution, the most precise available in open access), SRTM for the rest of the world (90m). Calculation is done directly from your track's coordinates — without sending the file to a server.
7-day forecasts for any point on your track. If the route climbs, a separate panel shows conditions at the highest point of the route.
Search along your track for all useful amenities: supermarkets, bakeries, pharmacies, petrol stations, water fountains. Plus accommodation: campsites, mountain huts, hotels, guesthouses. Filter by category, view on the map, add a stop in one click. Essential for planning an autonomous traverse.
Your work is kept in the browser. Reload the page without losing your tracks in progress. Close the tab — everything disappears cleanly, nothing remains on the server.
Questions asked by cyclists, trail runners and hikers before editing their GPS tracks.
Import your file, activate the Cut tool, then click on the map or on the elevation profile. The track splits into two independent files, each exportable separately.
Import your files simultaneously, select them in the track list, then click Merge. Assembly order can be automatically optimised so that endpoints connect. One GPX file as output, directly exportable.
Merge joins tracks end to end. Combine analyses the intersections between multiple crossing tracks and generates up to 5 viable loops without dead-ends — useful for assembling local trail paths, MTB loops or hiking trails into larger circuits.
In the Analysis panel, enable Surface by colour. The track is coloured by actual surface in 7 categories: tarmac, compacted, gravel, dirt, grass, rock. A chart shows the percentage breakdown.
Weather button in the Analysis panel. 7-day forecast for the start point. If your route climbs, a dedicated panel shows specific conditions at the summit.
Select your track and click Reverse. The route is flipped in one click — handy for turning an outward journey into a return.
Use Fix Elevation in the Edit panel. Elevations are recalculated from digital elevation models: EU-DEM / Copernicus for Europe (25m precision), SRTM for the rest of the world (90m). No file is sent to a server.
Simplify in the Edit panel. The Douglas-Peucker algorithm reduces the point count while preserving the general shape. Adjust the tolerance in metres and see the result in real time — a 50,000-point file can drop to 3,000 with no visible distortion. Essential for GPS devices with limited memory.
Click Draw / Route in the toolbar, place points on the map. Routing calculates the path automatically (road, cycling, trail, hiking). Export as GPX when ready.
Import your .fit directly — GPX Edit Pro reads Garmin FIT files without any intermediate conversion. The elevation profile and statistics appear immediately. Then export as standard GPX compatible with all sports platforms.
Cut at the start of the section to remove, then at the end. Delete the middle. Merge the two remaining pieces. Or switch to Edit points mode to delete point by point.
Split by intervals in the Edit panel. Choose the distance (e.g. every 10 km) or duration (every 2 hours) — each section becomes an independent track exportable separately. Handy for preparing stages of a long-distance journey or a multi-day tour.
The tool uses tiled data: EU-DEM / Copernicus for Europe (25m resolution, the most precise available in open access) and SRTM for the rest of the world (90m). Correction is applied point by point on your track, without sending the file to a server.
Enable Points of Interest (POIs) and filter by category: mountain huts, guesthouses, campsites, water fountains, supermarkets, bakeries, pharmacies, petrol stations, car parks, mountain passes, summits. Click a POI to automatically reroute your track to pass through it, then return to the main route. Essential for planning supplies and accommodation on a long-distance trip.
The elevation profile appears as soon as you import a file. Enable Gradient by colour to see steep sections on the map — green for flat, red for severe climbs.
Find the break between the two outings on the elevation profile — it often appears as an altitude jump or speed gap. Cut there with the Cut tool, then export each half separately as GPX.
Yes. The GPX export is in the universal format compatible with Garmin Connect, Wahoo ELEMNT, Suunto, Bryton, Polar, Coros, Sigma, Apple Watch (via Workouts), Strava, Komoot and RideWithGPS.
No. GPX Edit Pro runs entirely in your browser — your files never leave your device. Optional features (weather, elevation correction, routing) contact external APIs only with the coordinates needed, with no personal data.
Yes. The interface is optimised for mobile with a tool dock at the bottom of the screen and touch-friendly buttons. Compatible with Chrome, Firefox, Safari and Edge on Android and iOS. All editing, analysis and export features are accessible on mobile.
Yes. GPX Edit Pro is completely free: no ads, no account required. All features are accessible without restriction — editing, surface analysis, weather, PDF export, simulation and sharing.
Runners, cyclists, hikers — each uses the tool in their own way.
Practical tips for cyclists, trail runners and hikers who want to master their GPX files.
Before loading up your bags, knowing whether you'll be riding on 60% tarmac or 70% dirt track makes all the difference to preparation. GPX Edit Pro colours your GPX track by actual surface extracted from OpenStreetMap: tarmac, compacted gravel, dirt path, grass, rock. A chart shows the exact percentage breakdown. Result: you leave with the right bike, the right tyres and the right tyre pressure.
Your Garmin Edge or Forerunner records every outing in FIT format. To edit that file — remove a failed out-and-back, cut the first few warm-up kilometres, fix erratic elevations from a poor barometric signal — you need a GPX editor that reads FIT directly. GPX Edit Pro imports your .fit without any intermediate conversion, displays the full elevation profile and lets you cut, fix and re-export as standard GPX, ready to load onto Garmin Connect or send to Strava.
The elevation gain shown on platforms is often wrong — raw GPS altitudes unfiltered, erratic points caused by going under tree cover or through a tunnel. For reliable ascent figures, two steps: fix the elevations from a digital elevation model (EU-DEM 25m for Europe), then read the interactive profile. In GPX Edit Pro, hover over the curve to locate each pass on the map, identify steep sections with gradient colouring, and select a zone on the profile to extract a segment — useful for isolating a climb before a recce.
On a tour spanning several days — an Alps crossing, a Scottish Highlands tour, a Pyrenees traverse by bike — logistics depend on what's available along the route. GPX Edit Pro displays directly on the map the OpenStreetMap points of interest filtered by category: supermarkets, bakeries, pharmacies, campsites, mountain huts, guesthouses, petrol stations. Click a POI to see its distance from the track. One click reroutes your itinerary to pass through it, then back to the main route. Add waypoints with personal notes to remember opening times or contacts. Everything exports in the final GPX file with standard <wpt> tags — visible on your Garmin or Wahoo GPS.
No need for Komoot or Strava to plan a route. GPX Edit Pro includes a routing engine directly in the browser, with no install. Choose your profile — road cycling, MTB, trail running, hiking — then click the map to place waypoints. The optimal path is calculated automatically between each point, following roads and trails suited to your activity. You can also draw freehand for off-network areas. As you draw, the elevation profile builds in real time: elevation gain, distance and max altitude are visible before you've even finished. Export as standard GPX as soon as the route suits you.
You've prepared a route and want to share it with your group without going through a third-party platform? GPX Edit Pro generates a unique share link for each track, with a QR code — handy to display on screen or print on a route sheet. Your contact opens the link in their browser: the track displays directly on the map with the elevation profile, no account or sign-up on their side. They can explore it, check the statistics and download the GPX file to import on their own GPS. No data stored on the server beyond the shared file.
GPX Edit Pro includes an activity simulator with 7 sport profiles: hiking, trail running, road cycling, gravel, MTB, kayak and stand-up paddleboarding. Enter your age, weight and effort level (easy, moderate, intense), and the tool calculates an estimated duration via the Naismith formula calibrated segment by segment — climbs slow you down, gentle descents speed you up. The simulation also returns estimated average and max heart rate based on your physiological parameters, and an average cadence per sport. For water activities (kayak, SUP), elevation correction is disabled — distance is all that counts. Ideal for calibrating water and food needs or planning timings before a multi-day tour.
Faced with two options — going over the main pass or contouring via the valley, taking the direct road or the scenic alternative with less elevation gain — the figures shown on platforms are rarely enough to decide. GPX Edit Pro lets you import both files simultaneously and open the comparison panel to see side by side: total distance, elevation gain, elevation loss, max altitude, estimated duration, average speed. Both tracks are displayed together on the map in distinct colours, and their elevation profiles are overlaid. Enable surface detection on each one to also compare the proportion of tarmac and trails — useful before a gravel or MTB route.
Older Garmin Edge computers, entry-level GPS watches or certain Wahoo devices have a per-file point limit. A GPX from a long recording — an ultra-trail, multi-day hike or cycling tour — can exceed 50,000 points and cause slowdowns or a loading error. The built-in Douglas-Peucker algorithm reduces the point count while preserving the general shape: bends are kept, straight sections are simplified. Adjust the tolerance in metres and see the result in real time on the map before confirming — a 5m setting often brings 40,000 down to 3,000 points with no visible distortion.
Cut, merge, reverse or plan your route in a few clicks. No install, no account required.
