Free DICOM Viewer

Why Choose a Free Online DICOM Viewer?

Professional DICOM viewing software can cost hundreds of dollars per year in licensing fees. OsiriX MD requires a $69 annual subscription, RadiAnt DICOM Viewer costs $55 per license, and enterprise PACS solutions can run into thousands. For patients wanting to view their own scan results, students studying radiology, or physicians needing quick one-time access to imaging data, these costs are unnecessary. Our viewer provides the essential viewing capability at zero cost.

Free desktop alternatives like Horos and MicroDicom exist, but they require downloading and installing software — a process that can take 15-30 minutes and may not be possible on managed workstations, library computers, or borrowed devices. Our browser-based viewer eliminates the installation step entirely, making it the fastest path from DICOM file to viewable image.

Unlike some free online tools that add watermarks, require account creation, or limit the number of files you can view, our DICOM viewer has no restrictions. View as many DICOM files as you need, as often as you need, with full-quality output and no identifying marks on your images.
