How do I convert a NIFTI file to PNG using this tool?

Upload your NIFTI file (either .nii or .nii.gz format). Then choose the slice plane you need: axial, coronal, or sagittal. Adjust optional settings like slice index and scaling factor, then click Convert. After processing, you can download each PNG slice individually or as a ZIP archive.

Why would I need to convert NIFTI to PNG?

NIFTI is a 3D/4D volumetric format used in neuroimaging software like SPM and FSL, while PNG is a universal 2D raster format. Converting to PNG gives you 2D slices that can be easily embedded in publications, presentations, websites, or viewed in any image editor—without needing specialized medical imaging tools. It also reduces file size for sharing and enables quick visual inspection of scans.

How does the conversion handle resolution and orientation metadata from NIFTI?

When slicing a NIFTI volume, the converter preserves the original voxel intensity values and spatial resolution (e.g., pixel spacing) in each PNG. Orientation metadata, such as radiological vs. neurological convention, is applied to prevent mirrored slices. However, because PNG is 2D, the 3D geometry, coordinates, and affine transformations from the NIFTI header cannot be stored—only the pixel data from the extracted slice is retained.
