Convert GRB2 to WEBP

Online GIS converters cap file size and need an upload. reaConverter converts GRB2 to WEBP locally, whatever the size of the dataset.

Online converters too slow for your GRB2 files? reaConverter works locally and handles unlimited batches. All processing runs locally on your PC, so your files stay private and secure. No command line and no scripting, unlike the usual ogr2ogr route.

Technical note

How GRB2 and WEBP differ in practice

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. 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 GRB2. GRB2 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 GRB2 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 GRB2 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.

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 download memes and graphics all the time, but half are WEBP files that won’t open in my editing apps. reaConverter fixes this in two clicks. Now I can actually use the funny cat pics I save!

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.

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

GRB2 to WEBP 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 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.
