Export single slices or full series

Converting complex medical imaging scans from proprietary hospital formats into everyday web formats is a frequent challenge for patients and medical professionals. MedSlice allows you to extract exactly what you need:

  • Single Slice Extraction: Perfect when you need to embed a specific axial cut or anatomical finding into an email, presentation, or second-opinion request.
  • Batch ZIP Export: Automatically converts hundreds of CT or MRI cross-sections into numbered JPG/PNG files and bundles them into an organized ZIP archive.

Need to preview slices first? Use our online DICOM viewer to inspect series with full zoom and caliper tools before exporting.

High-quality JPG with correct Window/Level

Standard image converters fail on DICOM files because medical scanners record raw 12-bit and 16-bit photon absorption values rather than standard RGB pixels. Without accurate radiometric calibration:

Generic Converters

Produce all-black or completely overexposed white silhouettes by ignoring Hounsfield units and Rescale Slope.

MedSlice Engine

Preserves radiology presets (Bone, Soft Tissue, Lung, Brain) to output crisp, diagnostic-grade JPGs.

Frequently Asked Questions

How do I convert DICOM (.dcm) files to JPG online for free?

Drop your .dcm files or hospital CD folder into the dropzone above. MedSlice decodes the medical pixel data locally in your browser and lets you export individual slices or batch-download the entire series as a ZIP.

Why do converted DICOM images often look completely black or washed out on normal converters?

Standard image converters don’t understand 16-bit medical grayscale, Rescale Slope/Intercept, or Window Center / Window Width (W/L) DICOM headers. MedSlice applies clinical PACS windowing presets (CT Bone, Soft Tissue, Lung, Brain) to ensure exact radiological contrast.

What is the difference between single slice and batch ZIP export?

Single slice export saves the active diagnostic cut as a standalone high-resolution JPG or lossless PNG. Batch ZIP export converts all slices in the series in sequential order, compresses them into a single archive, and downloads them in one click.

What are the Free vs Pro export limits?

The Free tier allows exporting individual slices and testing batch conversion up to 5 exports per day. MedSlice Pro unlocks unlimited batch conversions, multi-gigabyte studies, PDF clinical report generation, and MP4 cine video rendering.

Are my medical images uploaded to an external server?

No. The entire conversion process runs inside your local browser memory using WebAssembly. Your health data and patient scans never touch any remote server.
