Technical note

What changes when you convert ETS to GIF

ETS is a pyramidal whole-slide image: one file carries the same scanned slide at several magnifications, and the largest level can run past 100,000 pixels on a side. GIF holds a single flat picture at one resolution. That makes the magnification the decisive choice, because there is no sensible original size to fall back on here: the full-resolution level of a slide scan is larger than most image software will open at all. GIF is lossless, so nothing further is discarded during conversion. What it cannot do is restore detail that ETS compression already removed, and the output file will usually be considerably larger.

FAQ

ETS to GIF Conversion

What are ETS files?

ETS files are used in virtual microscopy to store the full-resolution image data captured from digital slides. Commonly generated by Olympus slide scanners, ETS files work alongside VSI (Virtual Slide Image) files to enable detailed, zoomable viewing of high-resolution microscope images. An ETS file contains the raw image tiles that make up the actual slide content, allowing for fast, fluid navigation across large specimens in digital pathology and biomedical research.

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.
