How it works
Section titled “How it works”- Select a map tile source
- Move and zoom the map to define the export area
- Select a zoom detail level or set a custom range
- Export tiles as a ZIP file
The visible map area is the export boundary.
Map sources
Section titled “Map sources”No map tiles are loaded until you explicitly select a source.
Available presets include:
- OpenStreetMap (test / standard)
- OpenTopoMap
- CARTO Positron
- CARTO Dark Matter (dark)
You may also provide a Custom tile source by entering a tile URL template.
Privacy notice
Section titled “Privacy notice”Tile sources are contacted directly by your browser.
When using Tor, this may involve Tor exit traffic unless you use an onion-based tile source.
Maps Exporter itself:
- Does not proxy requests
- Does not log usage
- Does not store data remotely
Zoom levels
Section titled “Zoom levels”Presets
Section titled “Presets”- Low: zoom levels 0 to 8
- Medium: zoom levels 0 to 12
- High: zoom levels 0 to 16
Advanced
Section titled “Advanced”Enable Advanced to set an exact zoom range manually.
Higher zoom levels significantly increase:
- Download time
- Disk usage
- Memory consumption during export
- File size (exponentially, as each level quadruples the tile count)
For a detailed explanation of zoom levels, including their impact on file sizes and performance, see Zoom Levels Explained.
Export controls
Section titled “Export controls”During export you can:
- Pause and resume downloading
- Stop and pack already downloaded tiles
- Cancel the export entirely
Progress indicators include:
- Percentage completed
- Number of tiles downloaded
- Total downloaded size
- Elapsed runtime
Output format
Section titled “Output format”The exported ZIP contains:
- A directory hierarchy of tiles organized by zoom, X, and Y
- A metadata file describing:
- Bounding box
- Zoom levels
- Tile source
- Creation timestamp
This format is compatible with Anonomi Offline Maps.
