KMZ to Interactive HTML Map

Turn a KMZ file — the zipped Google Earth format — into one standalone HTML map. The archive is unzipped on your device, the KML inside is parsed, and every placemark renders as a clickable marker, line or area. The exported file inlines the map engine, styles and all features, so it double-clicks open and works offline — no Google Earth, no QGIS, no upload.

What Is a KMZ File?

A KMZ file is a ZIP archive containing KML — usually a single doc.kml plus optional images, icons or overlays. Google Earth and Google My Maps save in KMZ because the archive keeps everything in one compact file, including custom icons. Renaming a .kmz to .zip and extracting it is the classic manual trick — this page does the same thing properly, in your browser, at readonly speed.

Because KMZ is binary and compressed, it can't be opened in a text editor or most lightweight viewers. This viewer unpacks the archive locally, finds the KML entry, and renders the placemarks as markers, lines and polygons with their names, descriptions and custom data fields intact.

What's Inside the Archive

Entry	How it is used	Required?
`doc.kml`	The KML entry parsed by this tool — preferred wherever it sits in the archive	✅ Yes
other `.kml` files	Used only when there is no `doc.kml`	Fallback
images / icons / overlays	Ignored for now; the geometry still renders	Optional

Inside that KML, the same fields as the KML tool apply: Placemark name, description, ExtendedData and the Point / LineString / Polygon geometry types.

How to Convert KMZ to an HTML Map

Drop your .kmz file — drag & drop, or click to browse. The archive is unzipped in your browser's memory; nothing is uploaded.
Check the summary — the status bar shows how many features were found and which geometry types they are.
Preview the map — pan, zoom and click any feature to see its popup fields. The view auto-frames your data.
Pick a basemap — keep it fully offline with "no basemap", or view on OSM streets / satellite imagery.
Download single HTML — one .html file with everything inlined: double-click, email, or host it anywhere.

Open KMZ Without Google Earth

Google Earth is the default answer for KMZ files — but it's a large download, unavailable on some platforms, and overkill for a quick look. If all you need is to see where the pins, paths and areas are, this page is the fast lane: open the KMZ in a browser tab, inspect it, and share a self-contained map file if you need to.

Have an uncompressed KML file instead? That has its own converter. And if the archive was exported from a mapping tool as GeoJSON, try the GeoJSON to HTML map converter.

Features

Unzips locally — the KMZ archive is decompressed in your browser; finds doc.kml wherever it sits in the archive.
Full KML parsing — Point, LineString, Polygon, MultiGeometry and gx:Track, with ExtendedData turned into popup fields.
Self-contained export — one HTML file with the map engine, styles and all features inlined. No CDN, no tracking, no expiry.
Offline mode — export with "no basemap" and the file opens without any internet connection.
100% private — nothing is uploaded, no signup, no server round-trip at any point.

FAQ

Is there an online KMZ viewer?

This page works as one as well as a converter — open a .kmz and it renders as an interactive map entirely in your browser. Unlike most online KMZ viewers, nothing is uploaded: the archive never leaves your device. And when you want a file instead of a view, the same page exports the standalone HTML map.

Does this work without installing Google Earth?

Yes — that's the point. Drop the .kmz file into the zone above and it unzips and renders entirely in your browser. No Google Earth, no QGIS, no desktop software of any kind. You can even export the result as a standalone HTML map to share with people who have nothing installed.

Is my KMZ file uploaded to a server?

No. The ZIP archive is decompressed in your browser's memory using a local unzip library, and the KML inside is parsed locally too. The file never leaves your device — you can verify this in your browser's network tab.

What's the difference between KMZ and KML?

KML is the plain-text XML format; KMZ is exactly that KML (usually named doc.kml) inside a ZIP archive, often together with icons and images. Use the KML to HTML map tool for plain .kml files.

My KMZ has multiple KML files inside — which one is used?

The viewer looks for doc.kml first (the standard entry point every tool writes). If the archive doesn't have one, it falls back to the first .kml file it finds. Auxiliary KML files are ignored for now.

Can I get the data back out as KML or GeoJSON?

The export is a self-contained HTML map — the fastest way to share or archive the view. If you need the raw data, the same preview works from the original KML: extract it from the KMZ with any ZIP tool, then convert it with the KML converter or a GeoJSON tool.
