How to convert WKT to KML

  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. KML is already chosen

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

  3. Download

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

Why ToAny

  • Private by construction

    The WKT to KML 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 KML: what to expect

WKT carries geometry only, with no names or properties. KML opens in Google Earth and Google My Maps. WKT is at home in writing a single geometry in a database or script; KML is the usual choice for places, routes and tours viewed in Google Earth.

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.

WKT vs KML

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.

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.

Questions

Are my geometries uploaded anywhere?

No. The WKT to KML 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 KML?

The values are kept. Anything KML 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 KML 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 KML. 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.
