Convert a file to GRD

To convert other file formats to the "Geospatial Grid or Preset" file type, you need software like Adobe Photoshop or a similar tool.

About GRD files

The .GRD extension identifies two distinct but widely used file types: Adobe Photoshop Gradient files and Golden Software Surfer Grid files.

1. Photoshop Gradient Files:
Designers use these files to store gradient presets - mathematical definitions of color transitions.

The Problem: These are proprietary settings files, not standard images. You cannot view them in standard image viewers or browsers, and opening them requires an expensive subscription to Adobe Photoshop. Users often struggle to extract the specific hex codes or visual representation without the native software.
The Solution: Convert these .GRD files to standard raster images like PNG or JPG to visualize the gradient instantly. For web development, extracting the color data to generate CSS code is the ideal workflow.

2. Surfer & GIS Grid Files:
Scientists and engineers use this format (often associated with Golden Software Surfer, Generic Mapping Tools, or DIVA-GIS) to store uniform grids of elevation or geospatial data.

The Problem: Many GRD files use proprietary binary encoding or legacy text formats (e.g., Surfer 6 vs. Surfer 7) that are incompatible with modern GIS suites like QGIS or ArcGIS. Users face 'unknown format' errors when trying to import data from older equipment or specific academic software.

Convert.Guru analyzes your GRD file, detects the exact format, and lets you read the text inside.

Users also converted GGR, GRID, JPG, ZIP, PNG, GRADIENTLIBRARY, GRADIENTS, XML, CSV, NC, SRF, PDF and GDR files.

FAQ

If you want to convert GRD file to TIFF, CSV, NETCDF, GGR, SHP, PNG, INI, CFG, CONF, CONFIG, JSON or XML, you can use Adobe Photoshop or similar software from the "Gradients or Spatial Data" category. In the File menu, look for Save As… or Export….

The GRD Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our GRD converter.
