Free online DICOM viewer
Drag in a DICOM folder and view it instantly in 2D and 3D — right in your browser. Nothing is uploaded: the files are decoded locally, so your images stay private on your device. Axial, coronal and sagittal views are MPR reformats rebuilt from the volume, and a slab MIP or MinIP is one click away.

How to use it
- 1.Click “Upload DICOM folder” and pick the folder from your scan CD or export.
- 2.The series are decoded in your browser (via dcm2niix compiled to WebAssembly).
- 3.Scroll slices, switch planes, rotate the 3D view, and adjust the window.
- 4.Optional: export a de-identified NIfTI copy, or get a plain-language AI report.
FAQ
- Is this DICOM viewer really free?
- Yes. Viewing DICOM files here is completely free and needs no account.
- Are my medical images uploaded to a server?
- No. DICOM files are decoded locally in your browser with WebAssembly, so the pixel data never leaves your device.
- What DICOM files does it support?
- Standard DICOM series from MRI, CT and similar modalities. Some vendor-specific compressed transfer syntaxes may need converting to NIfTI first.
- Can it explain what my scan shows?
- The viewer is free. If you want a plain-language explanation, you can create an account and run an AI report on your uploaded, de-identified scan.
- Can I open the CD or DVD from my hospital?
- Yes. Insert the disc, click “DICOM folder / CD” and choose the CD/DVD drive — the images open right here in your browser, on Windows or Mac, with nothing to install. Your files are never uploaded. If the disc stores its images in a compressed format we can’t read yet (for example JPEG 2000), you’ll get a clear message telling you the next step.
- Does it support MPR and MIP?
- Yes. The viewer reads the whole volume rather than a stack of pictures, so the axial, coronal and sagittal views are genuine MPR reformats. Under Advanced options you can switch on a slab projection and set its thickness in millimetres: MIP keeps the brightest voxel through the slab (vessels, bone), MinIP the darkest (air, airways). Projections work on one plane at a time; oblique and curved (CPR) reformats are not supported yet.
Want your scan explained in plain language?
The viewer is free — and so is understanding your radiologist’s report. Create an account, upload your scan (de-identified in your browser) and your report, and every finding is mapped onto the images, explained in plain language and scored — no card needed. An independent AI reading of the images is a paid extra. Informational only — not a medical diagnosis.
