Convert medical image files (ACR) online for free
The converter easily converts your ACR medical images to various formats - free and online. No Adobe Camera Raw or or other Camera Raw software needed.
To convert other file formats to the "Raw Image Cache File" file type, you need software like Adobe Camera Raw or a similar tool.
An .ACR file serves two drastically different purposes depending on your industry: it is either a modern AI caching sidecar for Adobe Camera Raw or a legacy medical imaging format.
For modern photographers, an .ACR file is a proprietary, binary cache generated by Adobe software when you apply heavy edits like 'Lens Blur' or 'Select Subject'. Unlike standard XMP files which store plain-text slider values, .ACR files store complex binary depth maps. This format cannot be opened directly and is not an image itself. It cannot be converted to JPG or PNG; attempting to do so will fail because the file lacks pixel data. You must keep the .ACR file alongside your original RAW image to preserve your masking edits.
In the medical sector, the .ACR extension represents the ACR-NEMA standard, an early 1980s predecessor to modern DCM (DICOM) files. These files contain actual raster images of MRI or CT scans but are entirely unsupported by standard web browsers or modern operating systems.
To overcome these strict compatibility limits, drag and drop your .ACR file here to analyze and convert it securely right in your browser. For clinical archiving of legacy medical scans, convert to modern DCM. For quick viewing or sharing with patients, convert medical .ACR files to universal JPG, PNG, or PDF.

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 ACR converter.
