Maps Exporter

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

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

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

Presets

Low: zoom levels 0 to 8
Medium: zoom levels 0 to 12
High: zoom levels 0 to 16

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

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

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.

Notes on tile usage

Public tile servers are intended for light usage only.

For large areas or high zoom levels, consider:

Running your own tile server
Using a provider that allows bulk downloads
Respecting provider rate limits and usage policies

Using Google Maps as source

Using Google Maps tiles might not be compatible with their Terms of Service. We wouldn’t want you to get in trouble.

So, hypothetically speaking, if you were to click on Custom and enter one of these tile URL templates:

Hybrid (satellite + labels):

https://mt1.google.com/vt/lyrs=y&x={x}&y={y}&z={z}

Roadmap:

https://mt1.google.com/vt/lyrs=m&x={x}&y={y}&z={z}

Satellite:

https://mt1.google.com/vt/lyrs=s&x={x}&y={y}&z={z}

You would risk bankrupting Google.

Please don’t do that.
