FAQ

ETS to APNG 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.

The APNG format is also known as "animated PNG" and is made up of a series of PNG files of the same size that are connected as an animation. APNG files are similar in function with GIFs, but they support better quality images and transparency.
