Drag and Drop Map — Preview KML Files on OpenStreetMap
Free drag-and-drop KML map preview for local SEO and Earth workflows: drop a .kml file and see coordinates on OpenStreetMap tiles — no Google Earth install or API key. Large rings are sampled for speed; files stay in your browser. Pair with KML Reader to extract coordinate lists.
Key features
- Drop any .kml with <coordinates> blocks
- Pins render on free OpenStreetMap tiles
- Large files show a sampled pin set for responsiveness
- Browser-only — files are not uploaded to a server
What Drag and Drop Map does
It reads KML XML locally, extracts coordinate blocks, and plots pins on an OpenStreetMap preview so you can confirm rings, paths, and pins landed on the right city before sending files to clients.
Why local SEO and map teams use it
Quick visual QA for Circle Generator rings, territory files, and client Earth exports — verify coverage landed on the correct neighborhood without installing desktop software.
Privacy & performance
Parsing happens in your browser session only. Very large coordinate sets are sampled on the map so the preview stays responsive.
How to use this tool (best practice)
1) Drop a .kml file (unzip KMZ first). 2) Confirm pins on the map. 3) Use KML Reader to copy coordinates for Merge, Reverse, or Geometries.
Frequently asked questions
Is this Drag and Drop Map free?
Yes. It is free on GBP Local Ranker’s KML Workbench at /free-tools/kml-workbench/drag-and-drop-map — no login required for basic use.
What files are supported?
KML text files (.kml) with <coordinates> elements. Unzip KMZ packages first and drop the inner .kml file.
Why are only some pins shown?
Very large rings may be sampled (up to 200 pins on the map) so the browser stays responsive.
Can I edit KML here?
This is preview-only. Use Reverse, Merge, Segment, or Geometries to transform coordinates.
Do map tiles need a Google API key?
No. OpenStreetMap raster tiles load without a Google Maps key.
Is my file uploaded to a server?
No. The file is read locally in your browser for preview only.
What if drop does nothing?
Confirm the file is XML KML with <coordinates>…</coordinates> blocks containing lon,lat values.
Can I click to pick a file instead of drag?
Yes — click the drop zone to open a file picker on supported browsers.
How do I extract coordinates after preview?
Open KML Reader, paste the same KML XML, and copy numbered coordinate blocks.
Where is the full KML Workbench suite?
Open All KML Workbench Tools at /free-tools/kml-workbench for reader, circle generator, merge, and more.
