How to Convert Multiple DNG Images to STP?
1. Download and Install reaConverter
Download reaConverter and install it in seconds. The setup is straightforward — no complex configuration, no extra software required. Apply image edits like resize, crop, or color adjustment while converting.
2. Load your DNG files
Add DNG camera files to reaConverter. Import folders of RAW photos and process them all with consistent settings.
Use drag-and-drop, folder browser, or right-click conversion from Explorer.
3. Select STP as output format
Select STP from the format list. Fine-tune color space, compression, and quality before converting your RAW photos.
4. Start DNG to STP 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 STP output.
Before you convert DNG to STP
DNG files hold unprocessed sensor data, so white balance and exposure are still adjustable. Converting to STP 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. DNG is made of pixels and STP 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 STP container, and that determines whether a CAD or design tool can work with it.
