How to Convert Multiple HEIF Images to DCM?
1. Download and Install reaConverter
reaConverter is a standalone Windows app — download, install, and start converting HEIF files in under two minutes. Need edits? Resize, rotate, or add watermarks during conversion.
2. Load your HEIF files
Add your HEIF files to reaConverter. Whether it's a handful or an entire archive, the batch engine processes them efficiently.
Browse for files, drag them in, or add entire folders at once. reaConverter queues everything automatically.

3. Select DCM as output format
Pick DCM as the output format. Set the destination folder and optionally configure resolution, quality, or file naming.

4. Start HEIF to DCM conversion
Start the conversion with one click. reaConverter handles everything and notifies you when it's done.

When the batch finishes, your DCM files are ready in the destination folder you chose earlier.
HEIF to DCM: what carries over and what does not
HEIF can carry an alpha channel and DCM cannot. Transparent areas are composited onto a solid background during conversion, so pick that background colour deliberately: white is the default, and it is rarely the right choice for a logo that will sit on a dark page. DCM is lossless, so nothing further is discarded during conversion. What it cannot do is restore detail that HEIF compression already removed, and the output file will usually be considerably larger.
