File Converter

Convert GPX, KML, or CSV files to and from GeoJSON.

How to use

Single File tab: upload or paste a GPX, KML, or CSV file and it converts to GeoJSON automatically.
Download the result as GeoJSON, GPX, KML, or CSV using the export buttons.
Batch (Multiple Files) tab: upload several files at once — they're parsed and merged into one combined GeoJSON.

Spatial File Conversion Coverage

Convert CSV, KML, and GPX input to a GeoJSON FeatureCollection and inspect it on a map. Export the result as GeoJSON, GPX, KML, or CSV. Processing runs in the browser.

CSV export represents Point features only. Input files are limited to 50 MB, and large files can affect browser memory and responsiveness.

Frequently asked questions

Why does exporting a Polygon to GPX look odd?

GPX 1.1 has no polygon concept, so the outer ring exports as a closed track — the same lossy convention other GPX tools use.

What's the file size limit?

Input files are capped at 50 MB to keep browser processing responsive.
