How to use Float GPX Editor

Open a GPX file and choose what to edit

Float GPX Editor is a map workspace for existing GPX files. Start with a copy of your recording, or choose “Explore a sample” to try an original synthetic track. You do not need an account. The file limit is 10 MiB and the project limit is 100,000 points, including routes and waypoints.

1. Click “Import GPX” or drop one or more .gpx files onto the app.
2. In Files, click an object’s name to make it current. Its points and statistics appear in Data and Elevation.
3. Use the visibility switch to show or hide an object, and “Fit to view” to locate it. Checkboxes separately choose tracks for merging and objects for export.

Inspect points on the map and elevation profile

In Browse mode, click a track line or its elevation curve to select a point. Data shows its coordinates and available original elevation, time and XML. Previous/next controls move through the selected object; the arrow keys do the same when focus is outside a form or dialog.

The profile uses recorded elevations only. Empty or broken curves indicate missing data rather than a terrain lookup failure. Statistics are calculated for the current track, and distances do not bridge segment gaps. On phones, switch between Files, Data and Elevation below the map.

Move, insert or delete a GPS point

Choose “Edit points”, select a point, then drag its handle. A completed drag is one undo step. You can also enter Latitude and Longitude in Data and click “Apply coordinates”. Values are WGS84 decimal degrees: latitude −90 to 90 and longitude −180 to 180.

“Insert point” places a new point after the current point when you click the map. An empty track starts with a new segment. New points contain coordinates only; the app does not invent time, elevation or sensor readings. Moving an original point keeps its other fields.

“Delete point” removes a single track point and connects the remaining points in that segment. This differs from deleting a middle range, which leaves separate segments. Undo restores the previous geometry.

Trim, delete a range or split a track

Select a track point and choose “Set start”. Select another point and choose “Set end”. The range follows the stored point order, including any segment boundaries; it is not a rectangle drawn on the map.

“Keep range” retains the inclusive range and removes the rest of that track. “Delete range” removes the inclusive range; removing the middle leaves separate surviving segments without a new connecting line. “Clear range” only clears the selection.

“Split here” creates two tracks at the current track point. It duplicates the boundary point so both sides keep their endpoint. Use the file list to select each result and inspect it before export. A GPX route must first use “Convert to track” for these track operations.

Reverse and merge tracks

“Reverse” reverses both segment order and point order within segments. Original point timestamps remain attached to their points, so recorded time can become backward and speed unavailable.

For a merge, use the checkboxes to select at least two tracks, open “Merge tracks”, choose their order and confirm the name. The result replaces those tracks and retains their separate segments. It does not join distant endpoints, snap to roads or create missing points. Waypoints and source file metadata are not removed by the merge. One undo restores the inputs.

Add waypoints and convert routes

Choose “Add waypoint”, then click the map to add a standalone place to the current file. Select it in Files to edit its name, description or coordinates. Waypoints are separate from the points making up a track.

Route points can be edited directly. “Convert to track” changes a route into a track so you can use range, split and merge. It uses the same existing points; it does not calculate a road route or provide turn instructions.

Manage local projects and undo changes

My projects lets you create, rename, duplicate, switch and delete local projects. The project name below the editor title is also a rename control. Geometry edits support up to 60 undo steps in the current session. A duplicate gives you a separate workspace for an experiment.

Autosave writes to this browser after a short delay. Wait for “Saved locally” before leaving, and download GPX as a portable copy. A save failure keeps the current project open and blocks switching to avoid losing unsaved changes; retry or export while the project is available. Browser storage is not cloud synchronization or a permanent backup.

Export the intended GPX content

Open “Export GPX” and choose the scope carefully. “Current file” retains the source version; “Selected” and “All content” create GPX 1.1. Selected uses checked objects, or the current object when nothing is checked. Hidden objects are still included if the scope selects them.

Wait for preparation and click “Download GPX”. The prepared file reflects the snapshot at preparation time. After more editing, prepare again. Export does not contain undo history or the entire local workspace.

Retained points keep their original recording fields, extensions and unchanged coordinate precision. Combined files preserve source metadata in application extensions; other tools may not show these. Reopen the result and check its geometry and destination-software behavior.

Use GPX with SpeedX on your phone

Float GPX Editor is the free browser companion to SpeedX, an iPhone and iPad app for live speed, altitude and trip recording. The editor works independently; SpeedX requires Pro for GPX import and export.

Files move between the two apps by download and manual import. Opening the SpeedX website, App Store or QR code does not transfer the GPX file or your browser project.

1. In SpeedX, open a saved trip, export it as GPX and keep the original copy. You can also start with a GPX recording from another tool.
2. Import that GPX into this editor and make your changes. If you have a route rather than a track, use “Convert to track” first; SpeedX imports tracks, not standalone routes or waypoints.
3. Select the tracks you want to transfer and export “Selected objects” as GPX 1.1. Each track needs at least two valid points. Click “Download GPX” to save the file.
4. If you edited on a computer, transfer the saved .gpx file to your iPhone or iPad using AirDrop or Files. The QR code opens the SpeedX product website only.
5. Open Trip Log in SpeedX, tap the import button at the top right and select the GPX file. Review the imported trip before using or sharing it.

• SpeedX creates a trip for each track, combines its segments and orders the points by time. To keep separate sections as separate trips, split them into distinct tracks before exporting.
• SpeedX fills missing point times during import. Times generated after inserting points or editing a route are not original recordings; statistics may differ from this editor.
• Standalone waypoints, routes and unknown extensions are not a full SpeedX trip backup. Keep the original GPX and use SpeedX’s backup feature for its saved trip data.

Keyboard shortcuts and practical limits

Shortcuts leave the usual behavior of text fields, buttons and dialogs intact. The map still needs a network connection for new basemap tiles; the GPX data itself is processed locally.
