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.
ESRI Shapefile is a vector data format developed by ESRI and one of the most widely used formats in GIS. A Shapefile actually consists of multiple files: .shp stores geometry, .shx stores spatial index, .dbf stores attributes, and .prj stores coordinate reference system information. Common practice is to package these files into a ZIP archive for distribution. Shapefile supports three basic geometry types: point, line, and polygon.
Converting S-57 to Shapefile 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 Shapefile 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 Shapefile 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 Shapefile 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 Shapefile file. Each input produces its own output, ready to use in your GIS, web map, or archive.
