About

NTF

UK NTF (National Transfer Format) is a geographic data exchange format defined by the UK Ordnance Survey, primarily used for distributing official UK topographic data. NTF is a complex binary format supporting multiple feature types and topological relationships. It is widely used in UK government and mapping departments.

GPX

GPX (GPS Exchange Format) is an XML-based GPS data exchange format and the de facto standard for exchanging data between GPS devices and applications. GPX supports three core data types: Waypoints (single location points), Routes (ordered path point sequences), and Tracks (GPS-recorded point sequences with timestamps). GPX files can be generated by various GPS devices, sports watches, and mobile apps.

Conversion trade-offs

NTF: limitations to know

  • UK-specific format with low international compatibility
  • Complex binary format, difficult to parse

GPX: what you gain

  • Supported by almost all GPS devices and apps for import/export
  • Human-readable, allows manual editing of routes and waypoints

Why convert NTF to GPX?

Converting NTF to GPX is one of the most common workflows in GIS. NTF data usually comes from desktop GIS software, government open-data portals, or data exchange with partners, while GPX is what modern tools, web maps, and platforms expect. This converter bridges the two: it reads your NTF files, keeps geometry and attributes intact, and writes clean GPX 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 NTF to GPX converter free?

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

Are coordinate systems preserved when converting NTF to GPX?

By default the output keeps the source coordinate system. If your NTF 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 NTF files at once and each one produces its own GPX output.

How to Use

  1. 1

    Upload your NTF file — drag and drop it onto the page, or browse from your device. You can add several files at once for batch conversion.

  2. 2

    The conversion runs automatically in your browser. No upload, no server — your data stays on your device the entire time.

  3. 3

    Download the GPX file. Each input produces its own output, ready to use in your GIS, web map, or archive.
