The Complete Maps.Me to Google Maps Migration Manual

When travelers decide to switch from Maps.Me to Google Maps, they immediately discover that Google Maps does not have a "Direct Sync" button. Furthermore, Maps.Me does not export to cloud Google accounts. To move your pins without losing custom folder names, descriptions, or coordinates, follow this battle-tested migration protocol using our KMB to KML converter. (If you also want your hiking tracks on a Garmin or OsmAnd GPS device, you can simultaneously use our KMB to GPX tool).

Where are .kmb files stored on Android and iOS?

πŸ€– Android Extraction Paths & Access:

On Android devices, your bookmark databases are stored inside the application sandboxes:

  • Maps.Me: /Android/data/com.mapswithme.maps.pro/files/
  • Organic Maps: /Android/data/app.organicmaps/files/

Android 11+ Scoped Storage Tip: Modern Android versions restrict direct access to the /Android/data/ folder. To copy your .kmb files, connect your phone to a Windows PC or Mac via USB file transfer, or open the system "Files" app (using an app shortcut or third-party manager like Shizuku / Solid Explorer).

🍎 iPhone / iPad (iOS) Extraction:

Open the Files app on iOS > tap On My iPhone > select the Maps.me or Organic Maps folder > open Bookmarks. You can share, AirDrop, or save the .kmb files directly. You can also export bookmarks right from within the Maps.Me / Organic Maps app using the native iOS Share Sheet.

⚠️

Google My Maps 2,000 Points Limit: Avoid the Dreaded Import Error

Google My Maps enforces a strict, hard-coded ceiling of 2,000 features (points, pins, and routes) per map layer. If you attempt to upload an unsegmented KML containing 2,001+ bookmarks, Google My Maps immediately aborts with an unhelpful error: "An error occurred while uploading your file".

How MapUnpack Solves This: When converting with MapUnpack, the Google My Maps Layer Auto-Split engine automatically groups bookmarks into cleanly numbered sub-layers (< 1,900 points per layer, e.g., "Favorites (Part 1)", "Favorites (Part 2)"). Your bookmarks import seamlessly on the first attempt with 100% pin preservation!

Google Maps "Saved Places" vs "Google My Maps": A Critical Distinction

Many users mistakenly try to import KML into standard Google Maps (maps.google.com). Standard Google Maps only supports saving individual pins one by one.

To manage entire collections of hundreds or thousands of pins with custom layers, Google provides a dedicated service: Google My Maps (mymaps.google.com). Once you create a map in Google My Maps and import your KML, it automatically syncs to your official Google Maps mobile app on your iPhone or Android!

How to View Your Converted Map on the Google Maps Mobile App

  1. Complete the import into Google My Maps on your computer browser using our online kmb to kml converter or kmb to gpx tool.
  2. Open the official Google Maps app on your iPhone or Android phone.
  3. Tap the "Saved" (or "You") tab at the bottom of the screen.
  4. Scroll to the very bottom and tap "Maps".
  5. Select your imported map. All your Maps.Me pins will illuminate on top of Google Maps' live vector satellite imagery! You can also export your dataset to kmb to geojson or kmb to csv.

πŸ”¬ Forensic Teardown β€’ 3 Min Read

Why Did MAPS.ME Trap Your Bookmarks in a Closed .KMB Format?

Unlike Google Earth (KML) and Garmin (GPX) which use open XML standards, MAPS.ME created a proprietary binary container using 32-bit packed Mercator integers and Protobuf serialization. Read our full forensic engineering teardown.

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.
