Step by step

How It Works

reaConverter offers the fastest, simplest solution for converting your GTIFF files into WEBP without GIS software - all files processed on your PC for maximum privacy and speed.

Technical note

Before you convert GTIFF to WEBP

GTIFF 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 GTIFF original if the data still has to go back into a GIS. GTIFF carries 16 bits per channel and WEBP carries 8, so tonal steps get coarser during conversion. It shows up first in smooth gradients such as skies. If the result will be edited further, move to an 8-bit format only at the very end.

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 GTIFF 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.

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!

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 use reaConverter's Watch Folder feature to automatically convert any WebP image dropped into a specific folder to JPG. This automates my entire image processing pipeline. Set it and forget it – that's how professional tools should work.

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.
