About GISConverters

GISConverters started with a file I could not upload. I had sensitive survey data to convert, and every online tool wanted me to send it to a server I knew nothing about. So I built a GIS file converter that never sees your data: it converts KML, KMZ, Shapefile, GeoJSON, GeoPackage, GML, GPX, DXF, DGN, CSV and Excel, and reprojects coordinates, entirely inside your browser. Nothing is uploaded, nothing is stored, and it is free.

Who builds it

I'm Ghulam Hasnain, a PhD researcher in space science and technology. I work with GIS and remote-sensing data every day in QGIS, ArcGIS and Google Earth, and I write and test every converter and every guide on this site myself. The editorial policy explains how.

How it works

Instead of sending your file to a server, the site runs GDAL/OGR, the open-source engine behind QGIS and most professional GIS software, compiled to WebAssembly and loaded into your browser. When you drop a file, it is read, converted and written back as a download on your own device. The engine downloads once, a few megabytes, and is then cached, so later conversions are fast and work offline. You don't have to take any of this on trust: you can check it yourself in two minutes.

How it stays free

There is no paid tier, no account and no file limit. Because conversion runs on your device rather than on servers, the cost of running the site is close to nothing. The site may show clearly labeled advertising to cover hosting. Ads never influence the content and never receive your files. See the terms and the privacy policy.

What it does not do

Raster imagery and elevation grids such as GeoTIFF are not converted here. This is a features-and-attributes tool. A few formats, such as AutoCAD DWG and Apache Parquet, need components that are not available in the WebAssembly build, so they are not offered. Very large files are limited only by the memory your browser can give the page.

Built with open source

• GDAL/OGR, an OSGeo project, running in the browser through gdal3.js.
• Leaflet for the map preview, with basemap tiles from OpenStreetMap contributors.
• JSZip for reading and writing zipped shapefiles and KMZ.
• Lucide icons, and the Manrope and JetBrains Mono typefaces, all self-hosted.
