Your data never travels
There is no upload endpoint and no database. What the page knows about your file is what is on your screen, and it forgets that when you close the tab.

How it works
Three steps and you are done. No account at any point.
-
1
Pick your file
Drag it onto the panel or browse for it. Several files at once is fine, and a KMZ is unzipped for you.
-
2
Check it on the map
Features are drawn with their attributes so you can confirm the geometry landed correctly before you commit.
-
3
Download the result
The converted file is written in memory and saved straight to your downloads. Nothing is kept anywhere.
Why in the browser?
Most online converters upload your file, convert it on their server and hold it for a while afterwards. For a hiking track that is fine. For revenue records, property boundaries and drone survey output it is not.
Fast on any connection
Only the page travels over the network. A 40 MB file converts at the same speed on a village broadband line as it does on fibre.
Output that validates
GeoJSON per RFC 7946 in WGS 84, with exterior rings wound counter-clockwise and holes clockwise. QGIS, ArcGIS, Leaflet and Mapbox all take it without a warning.
Frequently asked questions
Are my files uploaded to a server?
No. Every conversion runs as JavaScript inside your own browser. The file is opened from your disk, converted in memory and written back to your downloads folder. Open the network tab while you convert and you will see no request carrying your data.
What file size can I convert?
Around 100 to 150 MB comfortably, and more on a stronger machine. Because there is no server involved there is no plan limit, no queue and no daily cap. The only ceiling is your device memory.
Will my coordinate system be preserved?
KML is always WGS 84, so GeoJSON output is written in EPSG:4326 to match. Where a source format carries its own CRS metadata, that is read and reported before conversion so you know exactly what you are getting.
What happens to attribute data?
Attributes are preserved with their types intact. In KML that means ExtendedData and SchemaData become feature properties, so a survey number stays text and an area stays a number. Folder names are recorded too.
Can I convert several files at once?
Yes. Drop as many as you like and choose whether to merge them into one collection or download them separately. There is no batch limit, because there is nothing to queue.
Is it really free?
Yes, and there is no sign-up. It is built by Quantox, a GIS and e-governance company in Karad, because these are the tools we needed ourselves for municipal and Gram Panchayat work.
