We've launched a suite of free tools for working with geo files. Convert between GPX, KML, GeoJSON, and CSV formats, or validate your files for errors. Everything runs in your browser — your files never touch a server.

What's Available

Converters

Need to get a GPX file into KML format for Google Earth? Or convert a GeoJSON export into CSV for a spreadsheet? We support every combination:

  • GPX to KML, GeoJSON, or CSV
  • KML to GPX, GeoJSON, or CSV
  • GeoJSON to GPX, KML, or CSV
  • CSV to GPX, KML, or GeoJSON

Select a file and the conversion happens instantly — no button to click, no waiting. The converted file is ready to download immediately.

Validators

Not sure if your geo file is well-formed? Our validators check your files against their format specifications:

  • GPX Validator — checks schema compliance, tracks, waypoints, and metadata
  • KML Validator — verifies placemarks, styles, and Google Earth compatibility
  • GeoJSON Validator — validates features, geometries, and RFC 7946 compliance

Drop a file and validation runs automatically, showing results in a split pane with an interactive map preview of the geometries in your file.

Privacy First

All processing happens client-side in your browser using JavaScript. Your files are never uploaded to any server. There's no signup, no account, and no limits on how many files you can process.

This matters for geo data. Location files contain places you've been, routes you've taken, and waypoints you've saved. That data stays on your device.

Who Are These For?

  • Hikers and cyclists converting routes between GPS apps (Garmin, OsmAnd, Organic Maps)
  • Travelers moving saved places between Google Earth, Maps.me, and other apps
  • GIS professionals doing quick format conversions without firing up QGIS
  • Developers validating geo files before feeding them into applications
  • Anyone who exported data from one mapping tool and needs it in another format

Try Them Out

All tools are available at takeout-tools.com/tools. No signup required.
