Why GPX is the Gold Standard for Outdoor Navigation

While Google Earth and Google My Maps rely on our KMB to KML converter, the outdoor, bikepacking, and hiking world runs on GPX (GPS Exchange Format). GPX is an open XML schema specifically engineered for handheld GPS units, cycling computers (Garmin Edge, Wahoo ELEMNT), outdoor watches (Garmin Fenix, Coros, Suunto), and specialized wilderness navigation applications like OsmAnd, Gaia GPS, and Komoot.

If you recorded multi-day hiking routes or backcountry campsites in Maps.Me, converting your .kmb file to standard GPX 1.1 ensures that your waypoints (<wpt>) and track points (<trkpt>) are translated into native navigation routes that your GPS hardware can follow turn-by-turn. To learn how to extract this file from your smartphone storage, consult our Smartphone Extraction Guide, or read our technical autopsy on What is a .KMB File to see how track coordinates are decoded.

How to Import Your Converted GPX into Garmin Devices

  1. Generate GPX: Drop your .kmb file into MapUnpack and click "Download GPX (Garmin / OsmAnd)".
  2. Connect your Garmin: Plug your Garmin device into your computer via USB (it will mount as a mass storage drive).
  3. Copy to NewFiles: Open the Garmin drive on your computer, navigate to the Garmin/NewFiles (or Garmin/GPX) directory, and copy the downloaded .gpx file into this folder.
  4. Eject & Restart: Safely eject your device. Upon reboot, Garmin will process the GPX file and place your waypoints under Saved / Navigation > Waypoints.

How to Import GPX into OsmAnd (Mobile)

OsmAnd is one of the most powerful offline map apps for hikers. To import your GPX file:

Frequently Asked Questions

Everything you need to know about .kmb, Google Maps limits, and privacy.

Where are .kmb bookmark files stored on Android? β–Ό

On Android devices, Maps.Me stores bookmarks at /Android/data/com.mapswithme.maps.pro/files/ and Organic Maps at /Android/data/app.organicmaps/files/. On Android 11+, access these folders by connecting your phone to a PC via USB or using the system Files app.

Why does Google My Maps reject my converted KML file with an error (2,000-point limit)? β–Ό

Google My Maps enforces a strict ceiling of 2,000 features (points and routes) per layer. Files exceeding this limit trigger an import error. MapUnpack automatically splits large bookmark files into numbered layers (Part 1, Part 2) with under 1,900 points each.

Does MapUnpack preserve custom pin colors and categories? β–Ό

Yes. Maps.Me uses an internal 8-color preset palette (Red, Blue, Purple, Green, Yellow, Orange, Gray, and Pink). MapUnpack maps these IDs to standard hex color values and embeds them into KML styles and GeoJSON properties so your color categories remain intact.

Can I convert .kmb files directly on my iPhone or iPad? β–Ό

Yes. Because MapUnpack operates entirely in web browser memory without requiring desktop software, you can open mapunpack.com in mobile Safari or Chrome, select your .kmb file from the iOS Files app (On My iPhone > MAPS.ME > Bookmarks), and download standard KML or GPX directly.

Is my location data uploaded to any third-party server (100% offline privacy)? β–Ό

No. Unlike other converters that upload your files to remote servers, MapUnpack uses client-side JavaScript and WebAssembly. All parsing and conversion occur 100% inside your computer's local memory. No coordinates, filenames, or IP addresses are ever transmitted.

Does MapUnpack support Organic Maps bookmark files? β–Ό

Yes. Organic Maps is the open-source continuation of Maps.Me and uses the exact same .kmb binary format and OMIM data container. MapUnpack fully decodes Organic Maps .kmb bookmarks, tracks, and categories.
