Technical note

Before you convert GRB2 to JXR

GRB2 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. JXR 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 GRB2. GRB2 carries georeferencing: a coordinate reference system, and the real-world position and ground size of every pixel. JXR 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 GRB2 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 GRB2 data has GIS software. reaConverter renders it to JXR for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to JXR with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • 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.

Needed to convert my professional photos to JXR for long-term storage and was pleasantly surprised by reaConverter's handling of this format. The compression maintains exceptional dynamic range while reducing file sizes significantly compared to TIFFs. The batch processing saved me hours of work, and the quality preservation is outstanding - perfect for my HDR photography archive.

I firmly believe working with JPEG — the universal format supported by all devices and apps—is the wisest choice. reaConverter handles these conversions flawlessly.

FAQ

GRB2 to JXR Conversion

What are GRB2 files?

GRB2 is a file extension for the second edition of GRIB (General Regularly-distributed Information in Binary form), a World Meteorological Organization (WMO) standard for gridded weather, ocean, and climate data. Compared with the first edition, GRIB2 describes the data in greater detail and with higher precision, including coordinates stored in micro-degrees and a larger range of parameters, vertical levels, and message lengths. A file of this type is a series of messages, and a single message can contain several data fields that share the same origin and date. National weather services use it to distribute model forecasts, radar-derived products, and ocean and wave data. The same format is also found with the .grib2 and .grb extensions.

What are JXR files?

JXR or JPEG XR (JPEG Extended Range) is the extension used to define high resolution and high color depth images that provide better quality than regular JPEGs. The JXR format was initially developed as an HD Photo format for Windows' media viewers and editors and can support lossy or lossless compression. Its 48-bit RGB color range allows for accuracy in rendering images and better graphic representation. Additionally, JXRs can include an alpha channel which facilitates the editing of transparent layers.
