How to Convert Multiple HEIC Images to DCM?
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. Apply image edits like resize, crop, or color adjustment while converting.
2. Load your HEIC files
Start reaConverter and add your .heic 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 DCM as output format
Select DCM from 700+ supported output formats. Choose your destination folder and adjust settings to match your needs.

4. Start HEIC to DCM 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 DCM output.
Before you convert HEIC to DCM
HEIC 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 HEIC compression already removed, and the output file will usually be considerably larger.
