KMZ:
what's in the file
What is a KMZ file?
A KMZ is a zip archive with a KML file inside, usually doc.kml, plus the icons and images the KML refers to. Google Earth saves as KMZ by default because the result is smaller and travels as one file. Rename a .kmz to .zip and you can open it with any archive tool.
The KML inside is XML that describes places, lines and shapes, and how they should look: icons, line colours, camera positions for a fly-through. Google Earth reads and writes it. So do Google My Maps, QGIS and most route planners.
What the viewer shows
The paths. Every LineString in the KML is read, drawn as an outline and measured, and the lengths are added up. Start and end are taken from the first and the last point in file order. If the KMZ holds a dozen separate paths, the distance shown is the total.
Pins are counted as points but not drawn. Images, ground overlays and the styling are left in the archive. To see those, you want Google Earth. To see the path over terrain, you want the 3D preview button.
Other free GPS file tools
Same idea on every page: the file is read in your browser and nothing is uploaded unless you open the 3D preview.

Frequently asked questions
Is the KMZ viewer free?
Yes. Viewing a file, 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?
The KMZ is unzipped and read in your browser. When you open the 3D preview, the route extracted from it is sent to AvoMap to build that preview. The original file stays on your computer.
How do I open a KMZ file in Google Earth or Google Maps?
Google Earth opens a KMZ with a double-click on the desktop and from the share sheet on a phone. Google Maps itself does not; import the KMZ into Google My Maps and the layer shows under Your places. To check what the file holds first, drop it here.
Can it open plain KML files too?
Yes. Drop a .kml and it is read directly, no unzipping needed. There is also a KML viewer page in the footer with the same tool.
Can I see the images and overlays from the KMZ?
No. The viewer reads the paths and points and leaves the media in the archive. Google Earth is the place for the full presentation.
Can I see the route on a real map?
Yes. Once the file has loaded, Open 3D Preview shows the track over satellite terrain in the AvoMap editor. From there you can render it as a video.
Does it work on a phone?
It does. Any current mobile browser can open this page and pick a file from your phone's storage.
Can I convert the KMZ here?
Not on this page. The footer has KMZ to KML, KMZ to GPX and KMZ to SHP converters, all free and all running in the browser.
