About OSM
OpenStreetMap is the free map of the world that millions of volunteers draw. Its Export button, JOSM, Overpass and other tools save pieces of it as .osm, an XML file of the data as the volunteers entered it.
An OSM file holds nodes, single points with a place, ways, lines of nodes that make roads, rivers and the outlines of buildings, and relations, which group them into things like bus routes and areas with holes. Each carries tags such as highway=residential or a name.
Filepeek draws the data in your browser as layers by what it is: roads, rail, buildings, water, green spaces, boundaries and places, with multipolygons put together from their ways. Click anything for its tags, search the names, and save the features as GeoJSON, KML, GPX or CSV.

Questions
How do I open an .osm file?
Drop it on this page or choose Peek an OSM. It opens on a map, its roads, buildings, water and places as layers.
Can I edit OpenStreetMap with it?
No. Filepeek shows what the file holds and saves it in other formats. JOSM and iD edit OpenStreetMap.
How big a file can it open?
A town's or a city's data fits. Filepeek draws up to 3 million points on a computer and 750,000 on a phone, and Show details says when it left some out.
Can I convert OSM to GeoJSON?
Yes. Open it, choose Export, then Save the features as GeoJSON. Each feature keeps its tags.
