SWEREF99 TM is often required for delivery to municipalities, Lantmäteriet and Swedish GIS systems, where coordinates are given in metres (northing and easting).
Which file formats can I convert?
KML, KMZ, GPX, GeoJSON and CSV with coordinate columns. The result is delivered with SWEREF99 TM coordinates.
Can I choose a local SWEREF99 zone instead?
Yes. Select the correct zone (SWEREF99 12 00 to 23 15) as the target system in settings if your data requires a local zone.
Is the file processed locally?
Yes. All conversion happens in your browser and no coordinates are sent to a server.
