Offline basemaps

Tile Downloader

Download raster tiles (PNG, JPG, WebP) from XYZ/TMS tile servers into OGC GeoPackage — shareable, appendable, offline-ready.

Map Tile Downloader pulls raster tiles from an XYZ/TMS tile server and saves them into a SQLite OGC GPKG GeoPackage you can share with other apps.

Append to an existing GPKG to add multiple tables. OpenStreetMap raster tiles are hard-coded as a starting server; paste any public XYZ/TMS URL for other providers.

Coming soon: OGC WMTS, OGC WMS, ESRI MapServer, and ESRI ImageServer download paths.

Reference public tile servers via leaflet-providers and similar catalogs when building custom offline basemaps.
