About OpenStreetMap

OpenStreetMap (.osm) is the native XML format of the OpenStreetMap project. It stores nodes, ways, and relations with their associated tags, representing the full OSM data model. OSM data is also distributed in the binary PBF format (.osm.pbf) for more efficient storage and processing.

You might convert from OpenStreetMap format when you need to bring OSM data into a conventional GIS as point, line, or polygon features, when performing spatial analysis that requires standard vector format inputs, or when sharing OSM-sourced data with tools that do not have native OSM support.

Frequently asked questions

What geometry types are extracted from an OSM file?

The converter produces separate layers for points (nodes with tags), lines (open ways), and polygons (closed ways and multipolygon relations). You can select which layer to export in the output.

Is PBF format supported?

Yes — the OSM driver supports both .osm (XML) and .osm.pbf (binary) files. Upload either format directly.

How large can OSM files be for browser-based conversion?

Processing is done client-side using WebAssembly. Very large OSM files such as full country extracts of several gigabytes may exhaust browser memory. For large datasets, consider using osmosis or osmium-tool on the command line instead.
