Online converters too slow for your ECW files? reaConverter works locally and handles unlimited batches. All processing runs locally on your PC, so your files stay private and secure. Survey and cadastral data stays on your machine, with no upload at any point.

Step by step

How It Works

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

Technical note

Before you convert ECW to PDF

PDF is a page format, so each ECW image is placed on a page rather than converted into something else. Two settings decide how the result looks: the DPI, which fixes how large the image sits on the page, and whether a batch becomes one file per image or a single merged document. reaConverter can do either.

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 PDF for a report, an email or a slide, and handles a whole folder in one run.

  • Render every file in a folder to PDF with the same size and settings
  • Set DPI and output dimensions before the run, not afterwards
  • 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.

PDF is certainly a universal format, but sometimes you need JPEG files instead. For conversion, I use reaConverter - a lightning-fast program. No online editor can match its speed. Install it once, and you're set. Just open, convert, and done!
