Conversion from KMZ to GeoJSONSeq
Upload your Keyhole Markup Language - KMZ (compressed) data files (typically used in software like Google Earth, Google Maps, Locus Map or other software for outdoor activities) and convert them online in a few clicks to GeoJSON Sequence (GeoJSONSeq) format (most commonly used in software such as QGIS, ArcGIS or Manifold GIS) or to many other formats commonly used in GIS and CAD systems.
How it works
-
Data upload
Upload one or more Keyhole Markup Language - KMZ (compressed) 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 GeoJSONSeq files are packaged in ZIP format and ready for immediate download by the user.

Frequently Asked Questions
What is KMZ file?
The KMZ (Keyhole Markup Zip) format is a compressed version of KML, used to efficiently store and share geospatial data. A KMZ file is essentially a ZIP archive that contains one main KML file along with any related resources, such as images, icons, textures, or 3D models. This packaging makes KMZ ideal for distributing complete map visualizations that include both geographic features and their supporting media. KMZ files are widely supported in Google Earth, Google Maps, and various GIS applications, where they can be opened directly to display all included data in a single, self-contained file.
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.
