S-57 is an electronic navigational chart (ENC) data exchange standard defined by the International Hydrographic Organization (IHO), the official data format recognized by the International Maritime Organization (IMO) for Electronic Chart Display and Information Systems (ECDIS). S-57 data contains nautical features including water depths, channels, anchorages, and obstructions, serving as the key data foundation for safe maritime navigation.
DXF (Drawing Exchange Format) is a CAD data exchange format developed by Autodesk, the native interchange format for AutoCAD. DXF stores vector graphic data in text format, including points, lines, polygons, text annotations, and layer information. In GIS, DXF is commonly used for data exchange with CAD systems, and many survey and engineering data are provided in DXF format.
Converting S-57 to DXF is one of the most common workflows in GIS. S-57 data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while DXF is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your S-57 files, keeps geometry and attributes intact, and writes clean DXF output — entirely in your browser, so your data never leaves your device.
No. The conversion runs entirely in your browser using WebAssembly — your files never leave your device.
Yes, completely free with no sign-up and no usage limits.
By default the output keeps the source coordinate system. If your S-57 file uses a projected CRS (like UTM), you can search any EPSG coordinate system by keyword or code and reproject in one step. Note: output formats that require WGS84 by specification (KML, KMZ, GPX) always reproject to WGS84 automatically.
Yes — drop several S-57 files at once and each one produces its own DXF output.
Upload your S-57 file — drag and drop it onto the page, or browse from your device. You can add several files at once for batch conversion.
The conversion runs automatically in your browser. No upload, no server — your data stays on your device the entire time.
Download the DXF file. Each input produces its own output, ready to use in your GIS, web map, or archive.
