Technical note

How GRIB2 and TIFF differ in practice

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. TIFF 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.

Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see GRIB2 data has GIS software. reaConverter renders it to TIFF for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to TIFF 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.

My scanner saves everything as massive TIFF files, which are impossible to email. reaConverter lets me batch-convert them to searchable PDFs with tiny file sizes. My clients actually get their documents now!

I work in medical imaging, and we receive TIFFs from various sources. reaConverter converts them to DICOM‑compatible formats while preserving all pixel data. It's HIPAA‑friendly because it works offline – no data leaves our network. Essential for our lab.

I needed to convert TIFF to multi‑page PDF for an archive project. reaConverter handled it effortlessly – 2,000 pages in one batch. The output PDF was searchable (thanks to OCR) and had the same resolution as the originals. Absolutely brilliant.

I'm a graphic designer, and I often receive TIFF files from photographers. reaConverter converts them to editable PSDs with layers intact (where possible). It even keeps the colour profiles. This has streamlined my collaboration with clients tremendously.

My scanning software outputs TIFF, but I need PNGs for my website. reaConverter batch‑converts hundreds of TIFFs to PNG with perfect colour fidelity. The process is lightning‑fast, and the interface is so intuitive that even my non‑tech assistant uses it.

FAQ

GRIB2 to TIFF 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.
