KMZ to KML Converter
Unzip and convert any KMZ file into a clean, editable KML file directly in your browser. Nothing is uploaded to a server — your geographic data stays on your device.
Conversion Result
Upload a KMZ file above to see your extracted KML output here.
Built for real geospatial work
Every feature runs locally in your browser, so large placemark sets, folders, and embedded overlays convert quickly without a round trip to a server.
100% Client-Side
Conversion happens with JavaScript in your browser tab. Your KMZ file and the coordinates inside it are never transmitted anywhere.
Instant Results
Drop a file and get readable, formatted KML output in under a second, even for archives with many placemarks and folders.
Real-Time Validation
The tool checks file extension, ZIP structure, and internal KML presence before conversion, with clear inline error messages.
Placemark Summary
See a quick count of placemarks, folders, and file size at a glance before you download or copy the extracted KML.
Formatted Output
Extracted XML is presented in an indented, syntax-friendly view so you can review or copy it directly into another GIS tool.
Dark & Light Mode
Switch themes instantly with a single click — your preference is remembered for your next visit to the converter.
How the KMZ to KML conversion works
Select your file
Click the upload zone or drag a .kmz file directly onto the converter card.
Automatic validation
The tool checks the extension and ZIP signature to confirm it's a real KMZ archive.
In-browser extraction
JSZip unpacks the archive and locates the embedded doc.kml or first .kml entry.
Copy or download
Review the formatted KML, then copy it or download it as a standalone .kml file.
Understanding KMZ to KML Conversion
Anyone who has worked with Google Earth, GPS mapping software, or GIS platforms has likely come across both KMZ and KML file types. A KML file, short for Keyhole Markup Language, is an XML-based format used to display geographic data such as points, lines, polygons, and image overlays on a map. A KMZ file is simply a compressed, zipped version of a KML file, often bundled together with icons, textures, or ground overlay images into a single package. Converting a KMZ file to KML essentially means unzipping that archive and pulling out the readable, editable markup document hidden inside it.
People search for a way to convert KMZ to KML for a variety of practical reasons. Some need to open the placemark data in a text editor or code editor to inspect coordinates, folder structures, or style definitions. Others want to import the geographic data into a script, a spreadsheet, or a custom mapping application that only accepts plain KML rather than the compressed KMZ container. Developers building location-based tools frequently need raw XML access to parse points, paths, and polygons programmatically, which is far easier with an uncompressed KML file than with a zipped archive.
The conversion process itself is straightforward once you understand what a KMZ file actually is. Because a KMZ is fundamentally a ZIP archive with a different extension, unpacking it exposes a folder structure that typically contains a file named doc.kml at the root, along with an images or files subfolder holding any embedded icons or overlays. A dedicated KMZ to KML converter automates this unzip step, locates the correct KML document even if it has a nonstandard filename, and presents the extracted markup ready to copy, edit, or save.
This tool performs that extraction entirely inside your web browser using a client-side JavaScript ZIP library, which means the file you upload is read locally on your own device and never transmitted to a remote server. This approach keeps sensitive location data private, works offline once the page has loaded, and returns results almost instantly regardless of how many placemarks or nested folders the original KMZ file contains. For example, a delivery route exported from Google Earth as a KMZ can be converted here in seconds, letting you inspect every waypoint's latitude and longitude directly in the output panel.
Typical use cases include GIS analysts converting survey boundaries for use in open-source mapping tools, developers extracting coordinate arrays for a custom web map, real estate professionals sharing property boundary outlines in an editable format, and hobbyist GPS users who exported a hiking trail from Google Earth and now want to tweak the raw XML by hand. Whatever the reason, having a fast, reliable, browser-based way to convert KMZ to KML removes a small but recurring friction point from working with geographic data, and this converter is built specifically to solve that problem well.
Frequently asked questions
Open Google Earth, select the placemark, path, or folder you want to save in the Places panel, right-click it and choose "Save Place As," then pick KMZ from the file type dropdown before saving it to your device.
Upload your KMZ file to this converter above. It unpacks the compressed archive directly in your browser and extracts the plain-text KML document, which you can then review, copy, or download instantly for editing.
KML is an uncompressed XML file describing geographic data such as points and shapes, while KMZ is a compressed ZIP archive that bundles a KML file together with images, icons, and overlays into one smaller package.
