How to Convert Multiple HPG Files to TIFF?
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 HPG files
Start reaConverter and add your .hpg files. The software processes everything locally, so your files never leave your computer.
Use drag-and-drop, folder browser, or right-click conversion from Explorer.

3. Select TIFF as output format
Select TIFF from 700+ supported output formats. Choose your destination folder and adjust settings to match your needs.

4. Start HPG to TIFF conversion
Click Convert to start the batch. reaConverter processes files quickly and shows you the status of each one.

Once done, reaConverter shows a summary. Click 'Show converted files' to jump straight to your TIFF output.
How HPG and TIFF differ in practice
HPG describes geometry rather than pixels, so it has no inherent resolution. The conversion renders it at whatever size you choose, and that choice is final: enlarging the TIFF afterwards will not recover the sharpness. Set the output dimensions or DPI before converting, not after.
