Step 1: zip the right files together
A shapefile is never just .shp. You need at minimum .shp + .dbf, and you should always include .prj so the coordinate system is preserved. Select the files in your OS file manager and create a single .zip.
Step 2: drop the zip into the viewer
Open the Shapefile Viewer and drag the zip onto the upload box. Parsing happens in your browser — files never leave your device.
Step 3: explore your data
Click any feature to see its attributes. Use the layer panel to toggle visibility. The viewer auto-fits to your data extent.
Step 4: save, share, or convert
For one-off inspection, you’re done. To save the map, generate a shareable URL, or convert to GeoJSON/KML, sign up free.
Frequently asked questions
Why does my map appear blank or in the wrong place?▾
Your shapefile is probably in a projected CRS (UTM, State Plane) and you didn’t include the .prj file. Add the .prj to your zip and try again.
Is there a file size limit?▾
Around 20–50 MB practical in the free in-browser viewer. Use the signed-in /shapefile tool for larger files (web worker streaming).
Can I open KML or KMZ this way?▾
Use the KML → GeoJSON converter instead. KMZ should be unzipped first.
