Offline Maps

Save maps for offline viewing with Quick Save or Full Offline mode

Last updated: February 7, 2026

Offline Maps

Mapiry lets viewers save maps for offline access, so they work even without an internet connection. This is a Pro feature — viewers can save maps created by Pro users.

Overview

When viewing a map created by a Pro user, viewers see a "Save Offline" button. This opens a dialog with two options:

  • Quick Save — Fast, lightweight offline snapshot
  • Full Offline — Complete regional map download for full offline rendering

Offline maps are stored entirely in the viewer's browser using IndexedDB and Cache Storage. No app installation required.

Quick Save

Quick Save caches the map tiles that are currently loaded in your browser, along with the map's location data.

How It Works

  1. Click "Save Offline" on any Pro user's map
  2. Select "Quick Save"
  3. Currently loaded tiles and map data are cached
  4. The map is available offline at whatever zoom level and area you were viewing

Best For

  • Quick access to a map you've already been browsing
  • When you know the area you'll need
  • Saving storage space on your device

Limitations

  • Only caches tiles you've already loaded (current viewport and zoom)
  • Zooming beyond cached tiles will show blank areas
  • Uses Mapbox tiles (the same as the online version)

Full Offline

Full Offline downloads a complete regional PMTiles file, giving you full map rendering with zoom and pan support — even without internet.

How It Works

  1. Click "Save Offline" on any Pro user's map
  2. Select "Full Offline Map"
  3. Mapiry identifies the correct region for the map's location
  4. Regional map data (powered by OpenStreetMap) is downloaded to your browser
  5. A progress bar shows the download status
  6. Once complete, the map renders fully offline using MapLibre GL JS

Supported Regions

Full Offline is available for maps in these regions:

Asia:

  • Singapore
  • Malaysia
  • Thailand
  • Japan
  • South Korea

Europe:

  • United Kingdom
  • Germany
  • France

Oceania:

  • Australia

United States (cities):

  • New York City, Los Angeles, Chicago, San Francisco Bay Area, Miami, Seattle, Washington D.C., Boston, Houston, Las Vegas

If a map's location is outside these regions, only Quick Save will be available.

How It Renders

Offline maps use MapLibre GL JS instead of Mapbox, rendering OpenStreetMap data from PMTiles files stored in your browser. The offline view includes:

  • Full map with streets, labels, and landmarks
  • All location markers with category-based colors
  • Location popups with names and descriptions
  • An offline banner showing when the map was saved

The visual style may differ slightly from the online Mapbox version since it uses OpenStreetMap data with a light base style.

Storage

Full Offline downloads can range from ~50 MB (small cities) to ~3 GB (large countries like Japan). The exact size depends on the region and is shown before downloading.

Data is stored in your browser's Cache Storage and IndexedDB. You can remove offline maps at any time to free up space.

Managing Offline Maps

Viewing Offline Maps

When offline, simply navigate to the map URL as normal. If the map has been saved, it will load from your browser's cache automatically.

Removing Offline Maps

To remove a saved offline map:

  1. Open the map (while online or offline)
  2. Click the "Saved Offline" button
  3. Click "Remove"
  4. Both the map data and cached tiles are deleted

Storage Limits

Browser storage limits vary by device and browser:

  • Most modern browsers allow several GB of storage
  • If storage is full, the download will fail gracefully with an error message
  • You can check approximate storage usage in your browser settings

Requirements

  • Pro feature: Only maps created by Pro users can be saved offline
  • Modern browser: Chrome, Firefox, Safari, or Edge (recent versions)
  • Service worker support: Required for tile caching (supported by all modern browsers)
  • Sufficient storage: Full Offline requires space for the regional PMTiles file

Frequently Asked Questions

Q: Can I edit maps offline? A: No. Offline mode is view-only. You need an internet connection to edit maps.

Q: Do offline maps update automatically? A: No. Offline maps show data from when they were saved. To get updates, remove the offline map and save it again while online.

Q: Can I save any map offline? A: Only maps created by Pro users can be saved offline. The map owner must have an active Pro subscription.

Q: How long do offline maps last? A: Offline maps persist in your browser until you manually remove them or clear your browser data. They don't expire.

Q: Does Full Offline work in all regions? A: Full Offline is available for specific supported regions. If the map is outside these regions, you can still use Quick Save to cache loaded tiles.
