How VSI and GIF differ in practice

VSI carries 16 bits per channel and GIF carries 8, so tonal steps get coarser during conversion. It shows up first in smooth gradients such as skies. If the result will be edited further, move to an 8-bit format only at the very end. GIF is lossless, so nothing further is discarded during conversion. What it cannot do is restore detail that VSI compression already removed, and the output file will usually be considerably larger.

VSI to GIF Conversion: FAQ

What are VSI files?

VSI (Virtual Slide Image) is a proprietary whole-slide imaging format developed by Olympus for digital pathology and microscopy. It stores high-resolution scanned slides with multi-layer, multi-resolution data for medical and research applications.

What are GIF files?

GIF (Graphics Interchange Format) files are widely popular due to their ability to store animations and images in a relatively small size. Their compression algorithm implies the use of a limited color range (up to 256 colors), which means GIF files are great for storing static and animated images of a small size — like logos, icons or avatars, especially if you plan to transfer them or upload them online. GIF images, however, are usually not suitable for high-quality image rendering or printing.
