Read guide ↗Start with the file you already have
A GPX editor helps you inspect GPS data and make deliberate changes before saving another copy. If you only want to see a recording, import it and select a track. If you need a shorter section or several files in one, follow the trim or merge tutorial below.
The user guide explains every main control. The knowledge articles explain the file structure and statistics, while the FAQ covers local storage, privacy and common import or export questions. All guides have English and Simplified Chinese versions.
A short practice session
Open the editor’s synthetic sample, select a point on the elevation curve and inspect its coordinates. Set two range endpoints, keep the range and then undo. This lets you see exactly what a range operation changes without using a personal recording.
After trying your own file, download the result and reopen it. Check the beginning, the end, any gaps and the export scope. Keep the original file so you can compare or start again.
