Drop KMZ 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.
Press Convert. There is nothing else to set. The work happens in this tab.
Save the WKT, or download everything as one ZIP if you converted several files.
The KMZ to WKT converter is part of this page and runs inside your browser. Your map files are never sent to ToAny or to anyone else.
Nothing has to travel to a server and back, so the conversion starts the moment you press Convert, even on a slow connection.
No sign-up, no email address and no watermark. Add several files and download them together as a ZIP.
KMZ is a compressed archive, so text editors and many scripts cannot read it directly. WKT is what spatial databases and GIS libraries accept as text. KMZ is at home in KML with its icons and overlay images in one file; WKT is the usual choice for writing a single geometry in a database or script.
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. XML that declares custom entities is refused, and KMZ files are parsed without touching the network. The KML inside the KMZ is read; icons and overlay images in the archive are not carried over. WKT describes shapes only, so names and properties are left out; each feature is written on its own line.
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.

KMZ converterWKT 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.

No. The KMZ to WKT conversion runs inside your browser, on your own phone or computer. The file is not sent to ToAny or to anyone else.
The values are kept. Anything WKT has no way to express, such as formatting, formulas or nesting, is simplified or left out.
Yes. Add as many as you like, convert them together and download each result or all of them as one ZIP.
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 KMZ file, press Convert and save the WKT. There is nothing to install.
Yes. Files up to 200 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.
