Supported formats

KFB · JPEG SDPC · CSP · Aperio SVS · pyramidal TIFF / OME-TIFF · Hamamatsu NDPI / VMS / VMU · Leica SCN · Ventana BIF · 3DHistech MRXS · DICOM WSI · Zeiss CZI · Philips TIFF · Trestle

For slides with companion files, choose the whole folder containing the slide and its accompanying data. HEVC SDPC, fluorescence, z-stack navigation and Sakura formats are excluded. Support varies by scanner encoding.

Four output formats

SVS

Aperio-compatible pyramidal image. JPEG 2000 source tiles can be kept unchanged.

Pyramidal TIFF

Standard tiled, multi-resolution TIFF for OpenSlide-based viewers and pipelines.

OME-TIFF

Resolution levels for QuPath and Bio-Formats. OpenSlide shows the full-resolution level only.

CSP

A 2× image pyramid, with missing lower-resolution levels generated as needed.

Original tiles are copied when possible. Re-stitching or changing compression may require re-encoding; the result reports how tiles were handled. “Copy tiles exactly” stops conversion if source tiles would need recompression.

Removing identifying information omits label and macro images and identifying metadata. It cannot remove identifiers within tissue pixels or the file name.

For research and education. Check converted images in your viewer and keep the original slides. Third-party notices.
