About

KMZ

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.

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.

Conversion trade-offs

KMZ: limitations to know

  • Essentially a ZIP archive, needs to be extracted for processing
  • Limitations of the internal KML format still apply

MIF/MID: what you gain

  • Better suited for data exchange compared to TAB format

Why convert KMZ to MIF/MID?

Converting KMZ to MIF/MID is one of the most common workflows in GIS. KMZ data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while MIF/MID is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your KMZ files, keeps geometry and attributes intact, and writes clean MIF/MID 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 KMZ to MIF/MID converter free?

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

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

By default the output keeps the source coordinate system. If your KMZ 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 KMZ files at once and each one produces its own MIF/MID output.
