Technical note

GRB to PNG: what carries over and what does not

GRB is a container for scientific arrays, not a picture. One file usually holds several variables, such as temperature, pressure or wind, often across a series of time steps and a stack of vertical levels, each stored as floating-point values in its own units. PNG holds one flat image, so the conversion has to reduce all of that to a single slice and map its values onto shades. Treat the result as a snapshot for a report or a slide: the data itself stays in the GRB. GRB carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. PNG 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 GRB 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 GRB data has GIS software. reaConverter renders it to PNG for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to PNG 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 design stickers but could never cleanly resize my PNG logos without pixelation. reaConverter’s PNG-to-SVG tool keeps everything sharp—even when scaling up. My Etsy shop looks way more professional now!

I love that reaConverter can convert PDF pages to individual PNGs. I used it to extract images from a scanned document – each page became a high-res PNG with zero loss. It's like magic, but it actually works every time.

FAQ

GRB to PNG Conversion

What are GRB files?

GRB is a file extension used for GRIB (GRIdded Binary), a standard of the World Meteorological Organization (WMO) for storing and exchanging weather and climate data on a regular grid. The format is widely used for forecasts from numerical weather prediction models, such as temperature, pressure, wind, humidity, and precipitation. A file of this type is a sequence of messages, and each message holds one set of values for a single parameter, level, and time, together with a description of the grid and the date of the forecast. The format exists in two main editions: GRIB1, introduced around 1990, and the newer GRIB2, which uses the .grb2 or .grib2 extensions. Data are compactly packed, so large forecast archives take little space.

What are PNG files?

The PNG (Portable Network Graphics) file format was designed in the mid-1990s as an improved alternative to the previously existing JPG and GIF formats, and as an extension which would be particularly web-friendly. In time, PNG files have gained a wide popularity and are highly appreciated at the moment for their ability to provide a lossless compression of images, which translates in high-quality and detailed renderings.
