Download Country Boundaries — GeoJSON by Country & Level
Quick answer: choose a country and an administrative level, preview the result on the map, then download it as GeoJSON. Data comes from geoBoundaries and is assembled entirely in your browser.
Choose a country
Every country is available at its outermost level (ADM0). Deeper levels — states, districts, and smaller units — are only offered when that country actually publishes them.
Simplified loads far faster; full detail keeps every vertex.
Data from geoBoundaries. Files are assembled in your browser — nothing is uploaded.
What you can download
- ADM0 — the national outline, one feature per country.
- ADM1 — first-level divisions such as states, provinces, or regions.
- ADM2–ADM4 — progressively finer units such as counties, districts, and municipalities, where the source publishes them.
Coverage is uneven. France publishes down to ADM4 while the United States stops at ADM2, so unavailable levels are disabled rather than offered and then failing.
Simplified vs full detail
Every boundary ships in two versions. Simplified geometry drops vertices that do not change the shape at screen resolution and is usually several times smaller — the difference between a map that appears immediately and one that stalls a browser tab. Full detail keeps every original vertex and is the right choice for analysis, measuring, or cartographic output.
The map preview and the download always use the same version, so what you see is what you save.
How to use the file
- 1. Download the GeoJSON for the country and level you need.
- 2. Drop the file into the Studio viewer to inspect attributes, check coordinates, or filter units.
- 3. Convert it to Shapefile, KML, or GeoPackage when your desktop GIS or Google Earth needs another format.
Ready-made country layers
