We faced a massive challenge: digitizing 20 years of CGM archives into PNG format. Initial estimates projected months of work, but reaConverter's powerful batch processing and resolution scaling let us complete the project in weeks. Most impressively, it handled even our pre-1994 vector files flawlessly—zero errors, perfect fidelity.

FAQ

ETS to CGM 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 CGM files?

CGM (Computer Graphics Metafile) is a format that contains vector graphics information (clip art, drawings) associated with graphics design or CAD programs. As opposed to other types of metafiles, such as EMF or WMF, CGM files are not only supported by Windows, but can be used on different platforms too.
