Technical note

GTX to WEBP: what to expect from the conversion

GTX is not a map but a correction grid. Each cell holds the small offset needed to move coordinates from one datum to another, or the height of the geoid, the surface that turns a GPS height into a height above sea level. Survey and GIS software applies it silently during a coordinate transformation. Rendered as WEBP, it becomes a smooth picture of those offsets, useful for documentation or teaching, while the transformation itself still needs the original GTX. GTX carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. WEBP has nowhere to record any of that. The picture transfers intact, the location does not, so the output cannot be dropped onto a map afterwards without being placed by hand. Keep the GTX original if the data still has to go back into a GIS.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see GTX data has GIS software. reaConverter renders it to WEBP for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to WEBP with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • Stamp a text watermark, such as a project name or a date, on every image
  • Pick up new data automatically with Watch Folders, or script the job from the command line

Everything runs on your PC, which matters for cadastral, utility and client data that should not pass through an upload form.

I had a huge archive of WebP images from a client that I needed to convert to TIFF for printing. reaConverter handled it flawlessly – 500+ files in one go. No crashes, no quality loss. I'm genuinely impressed by the stability.

I use reaConverter's Watch Folder feature to automatically convert any WebP image dropped into a specific folder to JPG. This automates my entire image processing pipeline. Set it and forget it – that's how professional tools should work.

Google's WebP format is great for web performance, but not all platforms support it. reaConverter lets me convert WebP to JPEG and PNG in bulk, so I can use images everywhere. The batch processing is lightning‑fast, and the quality is identical to the original. A must‑have for any webmaster.

I downloaded thousands of WebP memes and wanted to share them with friends who use older phones. reaConverter turned them all to JPEG in minutes. Now everyone can enjoy the funny cat pics. Thanks, reaConverter, for being the hero of our group chat!

As a graphic designer, I often receive WebP files from clients who don't know any better. reaConverter converts them to PSD or PNG with layers intact (when possible). It's the only tool that gives me back editable files. Absolute game‑changer.

FAQ

GTX to WEBP Conversion

What are GTX files?

GTX is a grid file used by NOAA's VDatum software to convert heights from one vertical reference to another. Heights on maps can be measured from different surfaces, such as the ellipsoid used by satellite positioning, the geoid that approximates mean sea level, or a tidal level like mean lower low water, and the difference between these surfaces changes from place to place. A file of this type covers an area with a regular net of points and stores the height difference at each of them, so that a program can add it to a measured height and obtain the value in the other system. Earlier versions were text files, while current ones are binary. The format is also used for global geoid models and for national height transformations.

What are WEBP files?

WebP is an image file format released by Google in 2010 with the aim of challenging the leading positions of JPG and PNG in the domain of storing and transferring digital images. The purpose of the WebP format is to improve the speed of browsing by offering the same quality as JPEG or PNG, but in a smaller size. WebP images can contain both lossy and lossless compression. They continue, however, to be incompatible with some image viewers and browsers, and are often described by analysts as "work in progress" — a format that still needs to be developed.
