Convert DICOM to TIFF Online
Export DICOM medical images to TIFF (Tagged Image File Format) — the professional-grade image format preferred for archival storage, histopathology imaging, and applications requiring maximum bit-depth and color fidelity. TIFF preserves the full dynamic range of medical imaging data without any compression artifacts.

Why Convert DICOM to TIFF?
TIFF is the industry standard for archival-quality image storage in medical imaging, pathology, and scientific research. Unlike JPG or WebP which use lossy compression, TIFF supports uncompressed and lossless LZW compression modes that preserve every bit of the original image data. This makes TIFF the preferred export format when DICOM images need to be archived outside of PACS systems while maintaining full diagnostic quality.
Histopathology and microscopy workflows frequently require TIFF output because it supports multi-page files, 16-bit grayscale depth, and multiple color spaces. When converting DICOM images from digital pathology scanners, mammography systems, or high-resolution CT/MRI studies, TIFF preserves the full bit-depth that would be lost in 8-bit formats like JPG or PNG.
Many image analysis software packages used in medical research (ImageJ, FIJI, MATLAB, 3D Slicer) natively support TIFF import, making DICOM-to-TIFF conversion a natural bridge between clinical imaging equipment and research analysis pipelines.

Frequently Asked Questions
What is the advantage of TIFF over PNG for medical images?
While both are lossless, TIFF supports 16-bit grayscale natively (65,536 gray levels vs PNG's typical 256), multi-page documents, and is more widely supported in professional medical image analysis software like ImageJ and MATLAB. TIFF is also the required format for many journal submissions in radiology and pathology.
How large are TIFF files compared to DICOM?
TIFF files with LZW compression are similar in size to the original DICOM pixel data — typically 1-10 MB per slice depending on resolution. Uncompressed TIFF files can be larger. The tradeoff is universal compatibility with research tools without requiring DICOM-specific libraries.
Can I preserve 16-bit depth when converting DICOM to TIFF?
Yes. Our converter can output 16-bit TIFF files that preserve the full dynamic range of the original DICOM data. This is critical for quantitative analysis, dosimetry studies, and research applications where grayscale precision matters beyond what 8-bit formats can represent.
Is TIFF compatible with ImageJ and 3D Slicer?
Yes, both ImageJ/FIJI and 3D Slicer have excellent native TIFF support. Converting DICOM to TIFF before importing into these tools can simplify workflows, especially when working with DICOM files that use non-standard transfer syntaxes or compressed formats that these tools may not handle natively.
