About

MIF/MID

MapInfo MIF (MapInfo Interchange Format) is MapInfo's data exchange format. MIF files store geometric graphics data, and MID files store corresponding attribute data. Unlike TAB format, MIF/MID is a plain text format more suitable for cross-platform data exchange. Many GIS software use MIF/MID as a bridge for interacting with MapInfo data.

KML

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.

Conversion trade-offs

MIF/MID: limitations to know

  • Large file sizes, slow loading speed
  • Style support not as complete as TAB format

KML: what you gain

  • Deep integration with Google ecosystem, can be displayed directly in Google Earth
  • Supports NetworkLink for dynamic data updates

Why convert MIF/MID to KML?

Converting MIF/MID to KML is one of the most common workflows in GIS. MIF/MID 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 MIF/MID files, keeps geometry and attributes intact, and writes clean KML output — entirely in your browser, so your data never leaves your device.

Frequently asked questions

Are my files uploaded to a server?

No. The conversion runs entirely in your browser using WebAssembly — your files never leave your device.

Is the MIF/MID to KML converter free?

Yes, completely free with no sign-up and no usage limits.

Are coordinate systems preserved when converting MIF/MID to KML?

By default the output keeps the source coordinate system. If your MIF/MID 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.

Can I convert multiple files at once?

Yes — drop several MIF/MID files at once and each one produces its own KML output.
