About
This browser-based tool loads a ZIP containing Shapefile (.shp, .shx, .dbf) components and renders the polygons, lines, and points directly on a map, with all processing done client-side so no file is uploaded to a server. It converts the data to GeoJSON in WGS84 for download, and when a ZIP lacks a .prj file it lets the user pick between modern datums (WGS84/JGD2000/JGD2011) and the legacy Tokyo Datum, since coordinates from either datum look identical but can differ by roughly 464 meters in central Tokyo.
At a glance
This browser tool previews a shapefile on a map and converts it to WGS84 GeoJSON. It is worth using for a quick conversion when you know the source coordinate system and want to inspect the result before importing it elsewhere.
Good fit
People preparing a small public geospatial dataset for a web map.
Consider something else when
Use a scripted GIS pipeline when the conversion needs to be repeated, audited or applied to many files.
Start here
Load a public sample ZIP with its projection file. Compare a recognizable feature with a known location before using the converted geometry.
Cost and requirements
Browser tool. The ZIP needs the geometry, index and attribute files. Include the projection file when available.
Limits to know
Without a projection file, you must choose the source datum. A plausible-looking map can still be shifted if that choice is wrong.

Why it made the leaderboard
It saves GIS-adjacent developers from silently mislocating data by hundreds of meters when public datasets ship without projection files, without needing to install QGIS.
