TIGER/Line (Topologically Integrated Geographic Encoding and Referencing) is a series of geographic data products published by the US Census Bureau. TIGER data includes road networks, administrative boundaries, census areas, hydrographic features, and more, representing one of the most comprehensive public geographic datasets in the United States. RT1 is the classic exchange format for TIGER/Line data.
KMZ is the compressed archive format of KML, packaging the .kml file and its associated images, icons, and other resources into a single ZIP archive. KMZ files are smaller and easier to distribute via email or web download. Google Earth can open KMZ files directly, automatically extracting and rendering the geographic content.
Converting TIGER/Line to KMZ is one of the most common workflows in GIS. TIGER/Line data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while KMZ is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your TIGER/Line files, keeps geometry and attributes intact, and writes clean KMZ output — entirely in your browser, so your data never leaves your device.
No. The conversion runs entirely in your browser using WebAssembly — your files never leave your device.
Yes, completely free with no sign-up and no usage limits.
By default the output keeps the source coordinate system. If your TIGER/Line file uses a projected CRS (like UTM), you can search any EPSG coordinate system by keyword or code and reproject in one step. Note: output formats that require WGS84 by specification (KML, KMZ, GPX) always reproject to WGS84 automatically.
Yes — drop several TIGER/Line files at once and each one produces its own KMZ output.
Upload your TIGER/Line file — drag and drop it onto the page, or browse from your device. You can add several files at once for batch conversion.
The conversion runs automatically in your browser. No upload, no server — your data stays on your device the entire time.
Download the KMZ file. Each input produces its own output, ready to use in your GIS, web map, or archive.
