Map Data Workflow

Turn GIS data into something anyone can open

Not everyone who needs to see DAT 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.

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.

As a book scanner, I deal with TIFF files daily – they're huge. reaConverter compresses them to PDF or JPEG without losing any detail. I've saved terabytes of storage and still have archive‑quality images. This software paid for itself in storage costs alone.

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.

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!
