Convert GPX to FlatGeobuf Online — Free & Instant
Converting GPS tracks from GPX to FlatGeobuf produces a compact, indexed binary file that is ideal for storing and analysing large GPS datasets in QGIS or cloud-native GIS tools. FlatGeobuf retains all GPX geometry types and attributes while providing significantly better performance than GeoJSON for large track collections.

About GPX
GPX (GPS Exchange Format) is an XML-based format for storing GPS data including waypoints, routes, and tracks. It is the de-facto standard for sharing GPS recordings from devices like Garmin, Suunto, and smartphones. GPX is natively supported by Google Earth, Strava, Komoot, Garmin Connect, and virtually every GPS application. A GPX file can contain three types of data: waypoints (individual points of interest), routes (ordered lists of waypoints for navigation), and tracks (continuous GPS recordings with timestamps). GDAL reads and writes GPX natively.
Strengths
- +Universal GPS device compatibility
- +Supported by Strava, Garmin, Google Earth
- +Contains timestamps and elevation data
- +Human-readable XML
About FlatGeobuf
FlatGeobuf is a modern, high-performance binary format for geospatial vector data, designed for efficient streaming and cloud-native workflows. Based on FlatBuffers, it supports random access via HTTP range requests, making it ideal for serving large datasets directly from object storage like S3 without a tile server. FlatGeobuf is an OGC Community Standard and is supported by GDAL 3.1+, QGIS, Mapbox, and the GeoJSON ecosystem. Its compact binary encoding is significantly faster to parse than GeoJSON for large datasets.
Strengths
- +Extremely fast read/write — binary encoding
- +Supports HTTP range requests for cloud-native access
- +OGC Community Standard
- +Compact — much smaller than equivalent GeoJSON
Frequently asked questions
Q.Are GPX timestamps and elevation preserved?
Yes. All GPX attributes including timestamps and elevation are stored as FlatGeobuf feature properties.
