About

GMT

GMT ASCII Vectors is a text-based vector data format used by Generic Mapping Tools (GMT) software. GMT is widely used in earth science research and academic paper map making. The GMT format records geographic features as text lines, each containing coordinates and optional attribute information.

DXF

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.

Conversion trade-offs

GMT: limitations to know

  • Only used in GMT software ecosystem, low universality
  • Does not support complex attributes and style information

DXF: what you gain

  • Supported by virtually all CAD software and many GIS applications
  • Suitable for exchanging data with engineering surveys

Why convert GMT to DXF?

Converting GMT to DXF is one of the most common workflows in GIS. GMT 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 GMT files, keeps geometry and attributes intact, and writes clean DXF output — entirely in your browser, so your data never leaves your device.

Frequently asked questions

Are my files uploaded to a server?

No. The conversion runs entirely in your browser using WebAssembly — your files never leave your device.

Is the GMT to DXF converter free?

Yes, completely free with no sign-up and no usage limits.

Are coordinate systems preserved when converting GMT to DXF?

By default the output keeps the source coordinate system. If your GMT 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.

Can I convert multiple files at once?

Yes — drop several GMT files at once and each one produces its own DXF output.
