Maps that start the moment you drop in a file.
DropMaps is a browser-based GIS workspace for desktop and mobile. Drag in your layers, style them, edit them.
Plus a free desktop Raster Converter and a QGIS plugin to round-trip your work with the rest of your GIS.
For anyone who needs to show something on a map
A full GIS, with nothing to set up
Drop in any format
Shapefiles, File Geodatabase (.gdb.zip), KML/KMZ, GeoJSON, CSV, TopoJSON, GeoTIFF/COG and PMTiles — drag them straight onto the map.
Runs in your browser
DuckDB-WASM and MapLibre do the heavy lifting client-side. No upload, no server round-trip, no install.
Style & edit
Symbolise layers, edit attributes, draw and reshape geometry, and organise everything into layer groups.
Big rasters, no sweat
Cloud-Optimized GeoTIFFs and PMTiles stream via HTTP range reads — view large imagery without downloading it all.
Publish a map, not a file
Stay free and local forever, or go Pro to sync across devices, back up to the cloud, and share a live map with anyone — no account needed to view.
Local-first, always free
The full editor — import, edit and export every format — runs in your browser. Nothing leaves your machine unless you choose to sync.
Share a public link
On Pro, make and share a read-only map in minutes. Share a map to anyone via a link — a branded, read-only viewer with optional password, expiry and view stats.
Cloud sync & storage
Pro backs up and syncs your maps across devices, with 5 GB of storage included — add more in $1/mo USD per-10 GB packs whenever you need it.
