About TinyDICOM

All image decoding in this version happens inside your browser. Selected files are kept in memory for this tab and are not uploaded. Closing or reloading clears the workspace.

Included in this version

Local DICOM file and folder import, grayscale image viewing, uncompressed multi-frame images, stack scrolling, window/level, pan, zoom, distance measurement, presets, invert, and PNG export.

Format limitations

This first build supports standard uncompressed 8/16-bit DICOM images using Explicit VR Little Endian or Implicit VR Little Endian. It does not decode JPEG, JPEG 2000, JPEG-LS, RLE or other encapsulated/compressed transfer syntaxes, DICOMDIR, SEG, SR or 3D volumes. Some unusual DICOM files may not parse. Large studies depend on device memory.

Distance measurements are approximate, based on DICOM Pixel Spacing where available. This software is not cleared or validated for clinical diagnosis.
