How to convert KML to WKT

  1. Add your KML map files

    Drop KML 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. WKT is already chosen

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

  3. Download

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

Why ToAny

  • Private by construction

    The KML 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.

  • 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.

KML to WKT: what to expect

KML is XML tied to Google Earth's way of styling, and not all GIS tools read every feature. WKT is what spatial databases and GIS libraries accept as text. KML is at home in places, routes and tours viewed in Google Earth; 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 KML files are parsed without touching the network. WKT describes shapes only, so names and properties are left out; each feature is written on its own line.

KML vs WKT

KML

KML map file

KML is the format of Google Earth. It stores placemarks, lines and areas with names, descriptions and styling in XML, and can add camera paths for tours. It became an Open Geospatial Consortium standard in 2008. A KMZ is the zipped form.

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.

Questions

Are my map files uploaded anywhere?

No. The KML to WKT 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 KML to WKT?

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

Can I convert several KML 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 KML to WKT 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 KML file, press Convert and save the WKT. 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.
