Convert ECW to TIF

Technical note

How ECW and TIF differ in practice

TIF is lossless, so nothing further is discarded during conversion. What it cannot do is restore detail that ECW compression already removed, and the output file will usually be considerably larger.

Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to TIF 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.
