What is GeoTIFF Converter?

GeoTIFF to KML Converter turns any georeferenced raster into a KML Ground Overlay — a precisely positioned image layer for Google Earth and QGIS.

The tool extracts georeferencing metadata, reprojects the bounding box to WGS84, renders the raster as PNG, and packages everything into a KMZ archive.

How to Use GeoTIFF Converter

  1. Click to upload or drag and drop your .tif or .tiff GeoTIFF file.
  2. The tool automatically reads the file's CRS, bounding box, and pixel resolution.
  3. Review the detected WGS84 bounding box and metadata in the info panel.
  4. Select output format: PNG, KML, or KMZ (recommended).
  5. Click Download to save the output and open it directly in Google Earth.

Frequently Asked Questions

Q:How do I convert a GeoTIFF to KML?

Upload your .tif or .tiff file, select KMZ as output format, and click Download. The tool reads the embedded georeferencing metadata, reprojects the bounding box to WGS84, renders the raster as PNG, and packs everything into a KMZ GroundOverlay that opens directly in Google Earth.

Q:What is a KML Ground Overlay?

A KML GroundOverlay positions a raster image at exact GPS coordinates. The GeoTIFF bounding box sets the north/south/east/west corners so the image snaps to the correct location in Google Earth, QGIS, or any KML viewer.

Q:Which projections are supported?

WGS84 (EPSG:4326), Web Mercator (EPSG:3857), NAD83 (EPSG:4269), and all 120 UTM zones (EPSG:32601–32760 North/South). Files in unsupported projections still export as PNG.

Q:Does it upload my GeoTIFF to a server?

No. All processing runs entirely in your browser using geotiff.js, proj4.js, and JSZip. Your raster data never leaves your device.

Q:My GeoTIFF opens correctly in QGIS but the KMZ is in the wrong location. Why?

This usually means the GeoTIFF is in an unsupported or custom projection. Reproject the raster to WGS84 (EPSG:4326) in QGIS first.

Q:Can I convert a multi-band (hyperspectral) GeoTIFF?

Yes. Files with more than 4 bands will use bands 1, 2, and 3 as RGB.
