Convert GDB to BMP

Batch GDB to BMP conversion doesn't have to be complicated. reaConverter processes entire folders with consistent quality settings. Works offline with no internet required, so you can convert anywhere, anytime. Surveyors and planners use it to pass GIS data to colleagues who work in other software.

How It Works

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

Technical note

How GDB and BMP differ in practice

A GDB file holds geometry and an attribute table, and nothing at all about appearance. Colours, line weights, fills and labels are properties of the GIS project rather than of the file, which is why the same GDB looks different in every program that opens it. The BMP render therefore falls back on defaults and will not match the styled map you see in QGIS or ArcGIS. Expect a clean drawing of the geometry rather than a finished cartographic product. GDB coordinates are positions on the earth, tied to a stated reference system, and each feature carries its own row of attributes. BMP is a picture: the coordinates become pixel positions and the attribute table is dropped entirely. That is fine for illustration and no use as data, so keep the GDB original if anything downstream needs to query or reproject the features.

Map Data Workflow

Turn GIS data into something anyone can open

A map saved as BMP opens on any computer and any phone. reaConverter produces those from GDB in batch, entirely offline.

  • 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.
