Decrease file sizes

Hello, everyone. I’m trying to upload my ctscans, but the filles are really big, the resolution is too high. I wanna know how do you solve this kind of problem,

How do you reduce file sizes without losing quality?

Assuming you have microCT scans, read this tutorial: Tutorials/ImageStacks at main · SlicerMorph/Tutorials · GitHub

Here are a few strategies you can try to reduce your file size:

  • A. Crop to a specific Region of Interest (ROI): Focus only on smaller sub-regions. This is the only method that reduces file size without sacrificing high-resolution image quality.

  • B. Convert bit depth (e.g., 16-bit/32-bit to 8-bit): While lowering the bit depth reduces data size, it will affect image quality to some degree. Success depends heavily on the contrast of your features.

  • C. Downsample the data: You can bin the data (e.g., 2x2x2 or 3x3x3). This reduces overall quality, but finding the right downsampling factor can drastically shrink file sizes while keeping the quality acceptable.

  • D. Apply lossless compression: If you simply need a smaller file for storage or transfer, try compressing it into a ZIP file.
