Convert DICOM medical images (DCM) online for free
The converter easily converts your DCM DICOM images to various formats - free and online. No DCMTK or other Raster Image software needed.
To convert other file formats to the "Medical Image Format" file type, you need software like DCMTK or a similar tool.
A .DCM file is predominantly a Digital Imaging and Communications in Medicine (DICOM) file. It is the international standard for storing, transmitting, and viewing medical imaging information, such as MRIs, CT scans, X-rays, and ultrasounds. You can read more about the standard on Wikipedia. These files contain both high-resolution pixel data (the visual scan) and a structured header containing sensitive patient metadata.
The main disadvantage of the .DCM format is its lack of native consumer support. You cannot open these files in a standard web browser, Windows Photos, or macOS Preview. They require specialized clinical software like DCMTK or OsiriX. Furthermore, because Protected Health Information (PHI) is embedded directly in the file header, sharing the raw file is a privacy risk. Patients who receive their scans on a CD often find themselves completely unable to view their own health data.
To make these files accessible, conversion is usually necessary. For quick viewing, emailing, or web sharing, convert .DCM to JPG or PNG. This extracts the visual pixel data and naturally strips out the hidden patient metadata headers. For combining scans with medical records, convert to PDF. Drop your file here to view and convert it securely right in your browser. (Note: Roughly 2% of .dcm files are XML-based 3Shape dental scans or DiskCatalogMaker databases; converting those as images will fail).

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our DCM converter.
