Conversion from TIFF to KMLSuperoverlay
Upload your GeoTIFF data files (typically used in software like QGIS, ArcGIS, GRASS GIS or various software for working with GIS data) and convert them online in a few clicks to KMLSuperoverlay (kmz) format (most commonly used in software such as Google Earth) or to many other formats commonly used in GIS and CAD systems.
How it works
-
Data upload
Upload one or more GeoTIFF files (or a .ZIP / .7z archive).
-
Review and display
Reviewing input data parameters and displaying their extent on a map.
-
Conversion options
Settings for format options and conversion parameters.
-
Download result
Resulting KMLSuperoverlay files are packaged in ZIP format and ready for immediate download by the user.
Technical details

Frequently Asked Questions
What is the maximum allowed size of input data?
The maximum size of the uploaded file is 5 GB. If your file is larger, you can try to compress it into a ZIP file with the maximum compression level (9) or, even better, into a 7z file. The contents of the package will be automatically unpacked on the server.
How secure is my data?
All data transfers are performed using the encrypted SSL protocol, which ensures secure data transfer. Both uploaded and converted data is temporarily stored in the data center and is further processed according to the user’s request. After some time, the data is automatically deleted - there is no need to delete it manually.
