ESRI File Geodatabase is a file-based geodatabase format from ESRI using proprietary binary storage. It overcomes many Shapefile limitations, supporting massive data storage (single table exceeding 1TB), advanced data modeling (topology networks, subtypes, domains), and spatial indexing. GDB is the preferred data format for the ArcGIS platform, widely used in enterprise and government GIS systems.
KML (Keyhole Markup Language) is an XML-based geographic markup language originally developed by Keyhole and later acquired by Google, becoming an OGC standard. KML can describe points, lines, polygons, image overlays, 3D models, and other rich geographic content. It is the native format for Google Earth and Google Maps. KML files organize geographic data using tags and attributes, and support style definitions and network link functionality.
Converting File Geodatabase to KML is one of the most common workflows in GIS. File Geodatabase data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while KML is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your File Geodatabase files, keeps geometry and attributes intact, and writes clean KML 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 File Geodatabase 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 File Geodatabase files at once and each one produces its own KML output.
Upload your File Geodatabase 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 KML file. Each input produces its own output, ready to use in your GIS, web map, or archive.
