About OpenStreetMap XML

OSM XML is the human-readable export format used by the OpenStreetMap editor (JOSM) and the Overpass API. It carries every node, way, and relation in an extract along with their tag metadata. Most large extracts are shipped as PBF instead because XML is verbose, but small areas and Overpass results arrive as .osm.

Typical producers: JOSM, Overpass API, osmosis, osmium.
Typical consumers: JOSM, QGIS (osm plugin), Mapbox toolchain, pyrosm.

About GeoParquet

GeoParquet is the OGC-blessed extension to Apache Parquet that adds geometry columns (WKB-encoded by default) and a `geo` schema-metadata block. It is the format of choice for analytical pipelines — Athena, BigQuery, DuckDB, Polars, and Spark all read it directly.

Typical producers: DuckDB, GeoPandas, Sedona, BigQuery, Athena.
Typical consumers: DuckDB, GeoPandas, Polars, pyarrow, Sedona.

How to convert OpenStreetMap XML to GeoParquet

  1. Drop your OpenStreetMap XML file (.osm) on the area above, or click to browse.
  2. The file is parsed server-side — geometries are normalised to a GeoJSON FeatureCollection internally, then written out as GeoParquet.
  3. The converted file downloads automatically. No retention; nothing is kept on the server.

Want to inspect the geometry before converting? Use the full 3D viewer instead — it renders the file on a MapLibre globe with toggleable layers, then lets you convert from the same toolbar.

FAQ

Is the OpenStreetMap XML to GeoParquet converter free?

Yes. rooot viewer is free and requires no account. There are no per-conversion charges.

Do I need to install software?

No. The conversion runs server-side, the result is delivered as a download. Works in any modern browser.

Are my files kept after conversion?

Direct conversions through this page (the form above) do not persist files at all — the bytes are parsed in memory and the result returned. Persistence only happens when you use the main viewer's Open in roooute button, and persisted files are deleted within 24 hours.

What is the maximum OpenStreetMap XML file size?

50 MB per file.

Does the converter preserve attribute properties?

Yes — feature properties round-trip through the canonical GeoJSON intermediate. Schema differences between source and target formats may force lossy coercions (e.g. shapefile DBF column-name length limits), but rooot viewer applies sensible defaults.
