How to Convert Multiple GBR Files to PDF?
1. Download and Install reaConverter
First, grab reaConverter from the download button below. Installation is fast, and the software runs offline — no account or signup needed.
2. Load your GBR files
Launch reaConverter and drop in your GBR files. The software queues everything for batch processing with consistent settings.
Add files by dragging them in, browsing folders, or using the right-click menu from Windows Explorer.

3. Select PDF as output format
Choose PDF as the target format. Pick a destination folder or let reaConverter save files alongside the originals.

4. Start GBR to PDF conversion
Then simply press the Convert button and your conversion will begin in no time!

Once the conversion is complete, you can find your PDF files in the destination folder you selected.
How GBR and PDF differ in practice
GBR drawings carry layers, line weights, and a drawing scale, and PDF records how the drawing looks on a page. Layout, paper size, and scale are decided at conversion time, so set them deliberately: a drawing that reads correctly on screen can come out unusable if the scale is left at its default.
