Free KMZ to SHP converter online Convert KMZ files to shapefile in your browser. Unzipped on your device, nothing uploaded.
Turn a KMZ into a shapefile
without sending it anywhere.
Drop the .kmz here. It is unzipped in this tab, the KML inside is read, and you get a zip with .shp, .shx, .dbf and .prj for QGIS or ArcGIS.
Want to look at the route first? The 3D preview is one click, and optional.
How to convert a KMZ file to SHP online
Four steps, and the unzipping is done for you.
Step 1
Open the converter
This page. No account, nothing to install.
Step 2
Drop in your KMZ
Drag a .kmz onto the page, or click Select KMZ File. The archive is unpacked on your computer, not on a server.
Step 3
Check what was found
You get the outline, the length and the number of features. If that looks wrong, load another file.
Step 4
Download the shapefile
Click Download SHP File. A zip lands in your downloads with one shapefile per geometry type in the KMZ.
KMZ and shapefile:
what's inside and what comes out
What is a KMZ file?
A KMZ is a KML file zipped up, usually with the icons and images it refers to packed alongside. Google Earth saves as KMZ by default because the result is smaller and travels as one file. Rename one to .zip and open it and you'll find a doc.kml inside. The converter does that unpacking, then reads the KML the same way the KML to SHP page does.
Images and ground overlays in the archive are ignored. A shapefile has no way to hold them.
What is a shapefile?
The Esri format most GIS software reads natively. It is a set of files that belong together: .shp for the geometry, .shx as an index, .dbf as a table with one row of attributes per shape, and .prj for the coordinate system. The download here is a zip with all four, in WGS84, the same lat/lon the KML used.
One shapefile holds one geometry type. If the KMZ has pins and a path you get two shapefiles in the zip, one for points and one for lines. Placemark names and descriptions become columns in the .dbf, with names cut to ten characters.
KMZ vs SHP: key differences
The rows that explain most of what looks different after the conversion.
| Feature | KMZ | Shapefile |
|---|---|---|
| Files | One .kmz, a zip with a KML and media inside | .shp + .shx + .dbf + .prj |
| Format | Zipped XML | Binary geometry plus a dBase table |
| Geometry per file | Any mix of points, lines, polygons | One type per file |
| Attributes | Name, description, ExtendedData | Columns in the .dbf, names up to 10 characters |
| Images and overlays | Packed in the archive | Not supported, dropped |
| Coordinate system | Always WGS84 | Anything, declared in the .prj |
| Typical software | Google Earth | QGIS, ArcGIS, GeoPandas |

Same idea on every page: the file is read in your browser and nothing is uploaded unless you open the 3D preview.
Turn the KMZ into a 3D map video in the AvoMap editor
Google Earth can fly a tour along a KMZ path. The AvoMap editor does that with satellite terrain and a camera you control, and exports the result as an MP4 in up to 4K.
The editor is free to use. You pay per exported video.

Frequently asked questions
Is the KMZ to SHP converter free?
Yes. Converting, the stats and the 3D preview cost nothing. AvoMap charges for exported videos, and that pays for the free tools.
Does my file get uploaded?
No. The KMZ is unzipped, parsed and rewritten as a shapefile in your browser. Two things do leave the tab: the first and last coordinate, to look up the place names you see, and the route itself if you click Open 3D Preview. Skip the preview and the data stays put.
The KMZ has several KML files inside. Which one is used?
The first .kml found in the archive, which is doc.kml for anything Google Earth wrote. If you built the KMZ by hand with several KMLs, unzip it and convert each one on the KML to SHP page.
Why are there two or three shapefiles in the zip?
A shapefile holds one geometry type. If your KMZ has placemarks and a path, you get one file ending in -points.shp and one in -lines.shp. Add them as separate layers.
What happens to the images in the KMZ?
They're dropped, along with icons, colours and ground overlays. Shapefiles carry geometry and attributes, not media. The placemark names and descriptions do come through as columns.
What coordinate system is the output in?
WGS84, EPSG:4326, in decimal degrees. That is what KML uses, and the .prj in the zip says so. Reproject in your GIS if you need UTM or a national grid.
Can I drop a plain KML here too?
Yes. The converter tries KMZ first and falls back to KML. The KML to SHP page in the footer is the same tool with the other name on the door.
Is there a size limit?
None enforced. Everything happens in memory on your machine. A KMZ that unpacks to several hundred megabytes will be slow on a phone and fine on a laptop.
