How to convert WKT to KMZ

  1. Add your WKT geometries

    Drop WKT files onto the box above, or click it to choose them. ToAny reads the file's contents to detect the type, so a wrong extension does not matter.

  2. KMZ is already chosen

    Press Convert. There is nothing else to set. The work happens in this tab.

  3. Download

    Save the KMZ, or download everything as one ZIP if you converted several files.

Why ToAny

  • Private by construction

    The WKT to KMZ converter is part of this page and runs inside your browser. Your geometries are never sent to ToAny or to anyone else.

  • No upload, no queue

    Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.

  • Free, without an account

    No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.

WKT to KMZ: what to expect

WKT carries geometry only, with no names or properties. KMZ bundles a map with its icons and images in one file. WKT is at home in writing a single geometry in a database or script; KMZ is the usual choice for KML with its icons and overlay images in one file.

Every format is read into plain GeoJSON features and written out from there, so coordinates, names and properties carry over wherever the target has a place for them. Each geometry in the file becomes one feature without properties; WKT in a coordinate system other than latitude and longitude is refused. Altitude and per-point timestamps are kept; a line with timestamps is written as a Google Earth track that can be played back. The KML is zipped as doc.kml, the name Google Earth expects.

WKT vs KMZ

WKT

Well-known text geometry

WKT writes a geometry as text, for example POINT (30 10) or POLYGON ((30 10, 40 40, 20 40, 10 20, 30 10)). Spatial databases such as PostGIS use it. It describes shape only, without names or other attributes.

KMZ

KMZ map file

A KMZ is a ZIP archive containing a KML file, normally named doc.kml, and the icons and images it uses. Google Earth saves a placemark collection as KMZ so that the pictures travel with it.

Questions

Are my geometries uploaded anywhere?

No. The WKT to KMZ conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.

Is anything lost when converting WKT to KMZ?

The values are kept. Anything KMZ has no way to express, such as formatting, formulas or nesting, is simplified or left out.

Can I convert several WKT files at once?

Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.

How do I convert WKT to KMZ on Windows, Mac, iPhone or Android?

The steps are the same everywhere because ToAny runs in the web browser: open this page in a current version of Chrome, Edge, Safari or Firefox, add the WKT file, press Convert and save the KMZ. There is nothing to install.

Is there a file size limit?

Yes. Files up to 150 MB are accepted; a larger file is refused with a message. Beyond that the limit is your device's memory, since nothing is uploaded; a computer copes with large files better than a phone.
