Most GIS jobs aren’t analysis. They’re converting a file, fixing a coordinate system or checking what is in a dataset someone sent over. QuickMapTools does those jobs in the browser.
It runs GDAL compiled to WebAssembly, so files are processed on the user’s own machine and never uploaded. It covers format conversion between most common vector and raster formats, reprojection, coordinate conversion, clipping, buffering, dissolving and simplifying, geometry repair, file inspection, and downloads from web services, OpenStreetMap and Natural Earth. Longer jobs can be chained into workflows and run over a batch of files.
