View DICOM Files Online — Private & Free
DICOM files contain your medical scans (CT, MRI, X-ray). This guide shows how to view them safely online without uploading sensitive patient data to any server.
Quick Answer: View DICOM files privately at ViewAnyFile.app. Your medical images are processed locally — nothing is uploaded, nothing is stored.
When your hospital gives you a CD or USB with your scans, the files are in DICOM format (.dcm). Most online DICOM viewers upload your scans to a cloud server, raising privacy concerns about patient data.
The Problem with Most Online DICOM Viewers
Patient name, ID, date of birth, and study date are embedded in DICOM metadata. Uploading to a third-party server may violate hospital privacy policies and data protection law.
