DICOM Viewer

DICOM Viewer lets you inspect medical imaging files on Android phones, tablets and foldable devices.

Supported files:

- DICOM Part 10 and raw datasets: .dcm, .dicom, .ima and DICOMDIR with linked images

- NIfTI-1/2: .nii, .nii.gz and .nifti, including 4D volumes

- NRRD/NHDR: .nrrd, .nrrd.gz and .nhdr

- MetaImage: .mha and .mhd, including explicitly selected companion RAW data

Offline DICOM decoders include uncompressed little/big endian, RLE, Deflated, JPEG Baseline/Extended (8/12 bit), JPEG Lossless, JPEG-LS, JPEG 2000, HTJ2K and JPEG XL. Bilevel images, encapsulated uncompressed frames and deflated image frames are supported. Damaged files, unsupported video streams and unusual variants can still require another viewer.

Inspect image previews, frames or slices, technical metadata and Transfer Syntax. Adjust window center/width, zoom, palette and inversion, then share PNG previews or JSON metadata. Patient tags are hidden until you enable them.

Additional files and attachments:

- Browse ZIP contents, search and open entries, including DICOM without a filename extension. ZIP64, encrypted and multipart archives are not supported.

- PDF pages, zoom and password-protected documents.

- JPEG, PNG, WebP, GIF (first frame) and BMP images.

- Embedded video playback using codecs available on your device.

- Content previews for DOCX, XLSX, PPTX, ODT, ODS, ODP, RTF and text files, including CSV and TSV, with spreadsheet sheet selection. Macros and formulas are not executed; exact Office layout is not preserved. Older DOC/XLS/PPT files require conversion. HTML is displayed as plain text.

Archives, documents, images and videos are processed locally. Size and memory limits apply; large files may require a desktop viewer.

Files and medical data stay on your device for viewing. Sentry collects crash diagnostics, AppMetrica provides technical analytics, and InetTools-hosted PostHog measures feature usage, known extensions and standard codec identifiers. Filenames, paths, patient tags, study/patient UIDs, pixels and exports are not sent to analytics. PostHog has no session recordings or touch autocapture.

The interface supports system, light and dark themes, phones and tablets in both orientations, and folded/unfolded screens.

DICOM Viewer is for technical inspection and file compatibility checks. It is not a medical device and must not be used for diagnosis, treatment or clinical decisions.
