Map Data Workflow

Turn GIS data into something anyone can open

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

  • Render every file in a folder to BMP 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.

This online converter works perfectly for small batches of files. I occasionally need to convert BMP to JPG, and it doesn't make sense to install software for such simple tasks. It's much easier to just visit the site, click a couple buttons, and get the same quality result in seconds.

FAQ

HDR to BMP Conversion

What are HDR files?

The HDR file format (.hdr) is a raster image format designed to store high dynamic range (HDR) data, capturing a wider range of brightness levels than standard formats like JPEG or PNG. Developed by Radiance, it uses a 32-bit floating-point representation per channel, enabling realistic lighting, shadows, and highlights.

What are BMP files?

The BMP or Bitmap file format is a popular raster graphic format, compatible with a wide array of image processing software, both on PC and Mac computers. BMP files store grids of pixels and detailed information concerning color tones and shades, and are highly appreciated for their ability to provide increased quality images. However, due to the lack of any compression algorithm in storing pixel data, BMP images can often be very large in size and thus difficult to store or transfer.
