Convert Google Earth KMZ archives (.kmz) into clean, standard RFC 7946 GeoJSON in your browser. Unpacks compressed archives and extracts geographic placemarks with 100% privacy and zero server uploads.
Detailed side-by-side format architecture for KMZ Document (.kmz) and GEOJSON Document (.geojson). Every conversion executes strictly within isolated browser memory without network transit.
Drag and drop your .kmz file onto the working surface or use the system file dialog. File magic bytes are verified locally on device.
Select a quality preset (Lossless, Visually Lossless, Balanced, Smallest) or adjust advanced encoding switches in the options panel.
Click CONVERT to execute local WebAssembly compilation. Save the finished .geojson directly to local storage, or stage it for chaining.
Prefer local shell scripting? Run this standard POSIX command on your machine to achieve equivalent transcoding without a web interface:
# Convert KMZ to GEOJSON locally
pandoc input.kmz -o output.geojsonWorking with files across multiple web pages? The official convrtr Chrome Extension adds native Side Panel docking, right-click context menu media extraction, and visible viewport capture. Powered by the same zero-upload client-side WebAssembly engine.
KMZ (Keyhole Markup language Zipped) is the compressed format used by Google Earth and Google Maps. It packages a main KML XML file (typically doc.kml) along with embedded custom placemark icons, ground overlays, and 3D COLLADA models into a single ZIP container.
convrtr unzips the KMZ container entirely in browser memory using fast pure-JavaScript decompression, extracts the primary KML vector document, and parses all Point, LineString, Polygon (including inner cutout holes), and ExtendedData fields into an RFC 7946 compliant GeoJSON FeatureCollection.
The generated GeoJSON is 100% compatible with modern web mapping libraries (Mapbox GL JS, Leaflet, OpenLayers, Kepler.gl, D3.js) as well as desktop GIS suites (QGIS, ArcGIS Pro, Google Earth Pro, geojson.io).
Never. All ZIP decompression, XML parsing, and GeoJSON synthesis are executed client-side in your browser memory. Your sensitive geospatial boundaries never leave your machine.
KMZ Document (KMZ) and GEOJSON Document (GEOJSON) serve distinct roles across the digital workflow. Converting to GEOJSON provides optimized compatibility, modern compression efficiency, or standardized playback across web browsers, operating systems, and media production environments.
The output format (GEOJSON) is inherently lossless or supports lossless operation. Your original visual or audio fidelity is mathematically preserved without quantization artifacts.
Never. convrtr is architected with a strict zero-upload model. All processing, decoding, decompression, and encoding happen 100% locally on your machine using sandboxed WebAssembly and Web Workers. Your data never touches an external server, database, or analytics collector.
You can execute this conversion locally via command-line utilities such as ffmpeg, cwebp, or ImageMagick. For example: see the developer terminal recipe provided in the technical specifications dossier above. convrtr provides the identical local-first capability directly inside your browser without installing CLI packages.
Yes. You can drop multiple .kmz files into the instrument to process them concurrently in browser Web Workers, or click 'Open in Master Studio' to queue mixed formats, configure individual targets, and export as a single ZIP archive.
Convert web media, local files, and document assets directly in Chrome Side Panel using client-side WebAssembly, zero-server uploads, and the official convrtr browser extension.
A byte-level walkthrough of the MLW container format: the Root marker, the filename block, the AES-GCM payload, and the one part of the layout nobody has documented.
MLW uses a single fixed encryption key shared across every install of the app. What that means for whether unwrapping it counts as DRM circumvention — in plain English, not legal advice.
