Free DICOM Viewer — No Install, 100% Private
Open any DICOM medical image directly in your browser. No software downloads, no Java plugins, no account required. Our viewer handles MRI, X-ray, and CT files with full windowing controls, multi-slice navigation, and AI-powered analysis — all without your data ever leaving your device.
Upload DICOM FilesHow It Works
Drop Your Files
Upload .dcm files, ZIP archives, or entire DICOM folders. Our parser automatically organizes series by modality, date, and description.
Browse Your Images
Navigate slices with keyboard arrows or the slider. Switch between series in the sidebar. Apply windowing presets for bone, soft tissue, or brain.
AI Analysis (Optional)
Four AI models analyze your images independently. Get a synthesized report with structured findings, severity grading, and clinical recommendations.
The Last DICOM Viewer You Will Need
Zero Server Storage
Your DICOM files are parsed and rendered entirely in your browser using JavaScript, WebAssembly, and the Canvas API. Nothing is uploaded to any server. Files are stored temporarily in IndexedDB and cleared when you want.
Universal DICOM Support
Handles all standard DICOM transfer syntaxes: Implicit VR Little Endian, Explicit VR Little/Big Endian, JPEG Lossless, JPEG 2000. Works with files from Siemens, GE, Philips, Canon, Hitachi, and all other DICOM-compliant devices.
Multi-Series Organization
Automatically groups uploaded files by series. View MRI sequences (T1, T2, PD, STIR), X-ray views (AP, lateral), and CT slices in an organized sidebar with thumbnails.
Professional Viewing Tools
Windowing presets (Auto, Soft Tissue, Bone, Brain), zoom up to 4x with pan, distance measurement in millimeters using pixel spacing metadata, and full-screen mode.
AI Consortium Analysis
Four independent AI models (GPT, Gemini, Claude, Grok) analyze your images. Claude Opus synthesizes findings into a structured report with confidence levels and model agreement indicators.
Works on Any Device
Responsive design works on desktop, tablet, and mobile. No plugins, no Java, no Flash. Just a modern web browser — Chrome, Firefox, Safari, or Edge.

Frequently Asked Questions
What is a DICOM file?
DICOM (Digital Imaging and Communications in Medicine) is the standard format for medical images. When you get an MRI, X-ray, or CT scan, the images are stored as .dcm files. You can usually request a CD or digital copy from your imaging center.
Is this DICOM viewer really free?
Yes, the viewer is completely free with no limitations. You can view as many DICOM files as you want. AI-powered analysis is available for $10 per analysis session.
How do I get my DICOM files?
Request a CD or digital copy from the imaging center where your scan was performed. Most facilities provide this at no charge. You can also check if your patient portal offers DICOM downloads. The files typically come as a folder of .dcm files or a ZIP archive.
Is my medical data safe?
Your files never leave your browser. All parsing and rendering happens client-side using JavaScript. We cannot see, access, or store your medical images. When you close the tab or clear data, your files are gone.
Can I use this on my phone?
Yes. The viewer is fully responsive and works on mobile browsers. For the best experience with large MRI datasets, we recommend a desktop or tablet with more memory.
Do you support JPEG 2000 or RLE compressed DICOM?
Currently we support JPEG Lossless, Explicit VR, and Implicit VR transfer syntaxes. JPEG 2000 and RLE Lossless support is coming soon. Most MRI and X-ray DICOM files use supported syntaxes.
