Conversion from PBF to TopoJSON
Upload your OpenStreetMap OSM/PBF data files (typically used in software like OpenStreetMap, Overpass API or Geofabrik) and convert them online in a few clicks to TopoJSON format (most commonly used in software such as QGIS, D3.js, OpenLayers or Highcharts) or to many other formats commonly used in GIS and CAD systems.
How it works
-
Data upload
Upload one or more OpenStreetMap OSM/PBF files (or a .ZIP / .7z archive).
-
Review and display
Reviewing input data parameters and displaying their extent on a map.
-
Conversion options
Settings for format options and conversion parameters.
-
Download result
Resulting TopoJSON files are packaged in ZIP format and ready for immediate download by the user.
Technical details
Input data
| Format | OpenStreetMap PBF (Protocolbuffer Binary Format) |
|---|---|
| Description | Community map data dump; OSM primitives mapped to GIS layers (points/lines/polygons) on import. |
| File type | vector / single-file |
| Extensions | .osm.pbf, .osm (XML) |
| Note | Compact binary encoding of OSM nodes/ways/relations. |
| Supported geometries | POINT LINESTRING POLYGON |

Output data
| Format | TopoJSON (topological GeoJSON) |
|---|---|
| Description | Topology-aware variant of GeoJSON that references shared arcs. Great for political/admin boundaries with common edges. |
| File type | vector / single-file |
| Extensions | .topojson / .json |
| Note | JSON with shared arc topology; reduces duplication in boundaries. |
| Supported geometries | POINT MULTIPOINT LINESTRING MULTILINESTRING POLYGON MULTIPOLYGON GEOMETRYCOLLECTION |

Frequently Asked Questions
What is the maximum allowed size of input data?
The maximum size of the uploaded file is 5 GB. If your file is larger, you can try to compress it into a ZIP file with the maximum compression level (9) or, even better, into a 7z file. The contents of the package will be automatically unpacked on the server.
How secure is my data?
All data transfers are performed using the encrypted SSL protocol, which ensures secure data transfer. Both uploaded and converted data is temporarily stored in the data center and is further processed according to the user’s request. After some time, the data is automatically deleted - there is no need to delete it manually.
