How to Convert Multiple SR2 Images to HPG?
1. Download and Install reaConverter
reaConverter is a standalone Windows app — download, install, and start converting SR2 files in under two minutes. Need edits? Resize, rotate, or add watermarks during conversion.
2. Load your SR2 files
Add your SR2 files to reaConverter. Whether it's a handful or an entire archive, the batch engine processes them efficiently.
You can drag-and-drop files, browse to a folder, or add entire directory trees including subfolders.
3. Select HPG as output format
Set HPG as output format and select where to save your converted files. Customize quality settings if needed.
4. Start SR2 to HPG conversion
Click the Convert button to start. reaConverter will process all your files with the settings you selected.
When finished, your new .hpg files will be waiting in the destination folder.
How SR2 and HPG differ in practice
SR2 files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to HPG bakes those decisions into the pixels, and highlight recovery is no longer available afterwards. Set white balance and exposure before the run rather than after. SR2 is made of pixels and HPG is a geometry format, so the two describe images in fundamentally different ways. Check the result before sending it downstream: what matters is whether the output contains editable geometry or a picture placed inside a HPG container, and that determines whether a CAD or design tool can work with it.
