KML (Keyhole Markup Language) is an OGC standard XML format created for Google Earth and used widely across Google Maps, mobile mapping apps and GIS software. It stores placemarks, paths, polygons, styling and folder structure, which makes it ideal for sharing annotated maps with non-technical audiences. A KML file is plain text; when zipped with its assets it becomes a KMZ.
Need the other direction instead? WKT is well-Known Text — the geometry syntax used by spatial databases. WKT (Well-Known Text) is the OGC standard text representation of geometry — POINT, LINESTRING, POLYGON and their multi- variants — used throughout spatial databases like PostGIS, MySQL and SQL Server, and in SQL queries. It describes geometry only, one shape per line, which makes it perfect for pasting features into a database or pulling geometry out of one.
WKT encodes geometry only — feature attributes/properties are not part of the format and are dropped on conversion to WKT.

KML to WKT — FAQ
- How do I convert KML to WKT?
- Upload your .kml file using the converter above (drag & drop or click to browse). GeoMaps converts it to WKT instantly in your browser and gives you a .wkt file to download. No software to install and no signup required.
- Is the KML to WKT converter free?
- Yes — it's completely free with no usage limits, watermarks or account needed. We offer it as a free tool from GeoMaps, the platform for turning your data into interactive maps.
- Is my data private? Are my files uploaded to a server?
- No. The conversion runs entirely in your web browser using JavaScript — your file is never uploaded to any server. Because nothing leaves your device, it's safe for sensitive or confidential data and works even offline once the page has loaded.
- Can I convert WKT back to KML?
- Yes. Use our WKT to KML converter for the reverse conversion — every format on GeoMaps converts both ways.
- Anything to know about WKT output?
- WKT encodes geometry only — feature attributes/properties are not part of the format and are dropped on conversion to WKT.
- How large a file can I convert?
- Because conversion happens in your browser, the limit is your device's memory rather than a server quota — files up to tens of megabytes convert comfortably on a typical laptop. Very large datasets may be slower depending on your machine.
