BPG at a glance
BPG
BPG arrived in the mid-2010s when image engineers were looking for better post-JPEG compression before AVIF and JPEG XL had ecosystem momentum.
DCM at a glance
DCM
DICOM grew out of the need to exchange imaging data across scanners, archives, and clinical systems without throwing away the surrounding context that makes a medical image usable in practice.

FAQs
Why convert BPG to DCM?
Convert to DCM when the output must remain part of a medical-imaging workflow, preserving both image data and associated study metadata.
It is the correct target for diagnostic, archival, and interoperable clinical imaging systems.
What changes when converting BPG to DCM?
This conversion changes how the format behaves in downstream tools and delivery environments.
Moving to DCM removes animation support. Moving to DCM removes HDR content.
What should I review after converting BPG to DCM?
