GDAL · Isolated EU Worker
GIS File Conversion Utility.
Deterministic geospatial translations — no databases, no data retention.
Privacy-first conversion service for Shapefile, GeoJSON, GeoPackage and more. Files are processed on an isolated, short-lived GDAL worker (Fly.io, Frankfurt/EU) and deleted immediately after conversion — no persistent storage. Fully open spec mappings.

System Architecture & Security Spec
01
Deterministic Engine Core
Runs GDAL 3.10.3 from the Debian package, pinned in the worker image. The same file on the same converter always runs the same ogr2ogr commands.
02
Ephemeral Processing
Conversions run on an isolated, short-lived GDAL worker. Each upload is processed in a per-request temporary directory that is deleted in full the moment the job finishes — even on error.
03
Nothing Lost Silently
Coordinate systems are kept; only KML and GPX output is converted to WGS84, as these formats require. Where a target format cannot hold something (long field names in Shapefiles, areas in GPX), the report after each conversion lists every change.
