Technical note

GRIB2 to WEBP: what carries over and what does not

GRIB2 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. WEBP 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 GRIB2. GRIB2 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 GRIB2 original if the data still has to go back into a GIS.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as WEBP opens on any computer and any phone. reaConverter produces those from GRIB2 in batch, entirely offline.

  • 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.

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.

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.

FAQ

GRIB2 to WEBP Conversion

What are GRIB2 files?

GRIB2 is the second edition of the GRIB standard of the World Meteorological Organization (WMO), introduced in the early 2000s to replace the first edition. It stores weather, ocean, and climate data on a grid, and it is now the main format used by national weather services for publishing model forecasts, radar-based products, and wave and sea condition data. Compared with the first edition, it describes the data more precisely, supports many more kinds of products, and allows larger messages, so that a modern global forecast can be stored without loss of detail. A single file may contain many fields, such as pressure, wind, and precipitation, for different times and heights. The format is also found with the .grb2 and .grb extensions.

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.
