AWS HealthImaging adds JPEG XL support

Posted on: Feb 2, 2026

AWS HealthImaging now supports storing and retrieving lossy compressed medical images in the JPEG XL transfer syntax (1.2.840.10008.1.2.4.112). It is now simpler than ever to integrate HealthImaging with applications that require JPEG XL encoded DICOM data, such as digital pathology whole slide imaging systems.

With this launch, HealthImaging stores your JPEG XL Lossy image data without transcoding, which maintains the fidelity of your data and reduces your storage costs. Further, you can retrieve stored image frames in the JPEG XL format without the latency of transcoding at retrieval time.

JPEG XL support is available in all AWS Regions where AWS HealthImaging is generally available: US East (N. Virginia), US West (Oregon), Asia Pacific (Sydney), and Europe (Ireland).
