Microscopy Slide Viewer for Windows & Mac

Open CZI, ND2, SVS, DICOM, and TIFF files in one focused desktop app. Zoom through large images, inspect metadata, measure calibrated regions, add annotations, and export TIFF without a heavyweight image pipeline.

Why labs use SlideScope as a microscopy image viewer

One viewer across common microscopy formats

Instead of switching tools between Zeiss, Nikon, Aperio, and TIFF workflows, teams can standardize on one viewer for day-to-day inspection and review.

Built for review, not just import

SlideScope focuses on the tasks teams repeat constantly: open the image, move around it smoothly, inspect metadata, compare slices, and measure what matters.

Simple distribution for subscriptions

Teams can request the app quickly, subscribe with PayPal or card approval, and stay on one paid monthly subscription without complex onboarding.

What SlideScope helps your team do

Need How SlideScope helps
Open common microscopy files Support for CZI, ND2, SVS, TIFF, and exported review workflows on Windows and macOS, and since version 1.10.0 for VSI, OIB and OIR, LSM, ZVI, Leica LOF and XLEF, DeltaVision, MetaMorph, and OME-Zarr files, and since version 1.20.0 for ICS/IDS, Gatan DM3/DM4, and Olympus SIS files, with the acquisition metadata they record.
Review very large images Smooth zoom and pan plus remote URL loading with smart local caching for large files.
Check spatial scale Calibrated measurement tools keep review tied to real-world distances.
Share what you are seeing TIFF export and share package workflows make handoff easier across labs and collaborators.

How to choose a microscopy image viewer

Teams usually start with one practical question: can one viewer open the files they actually receive and keep review moving with measurements, metadata, and export built in. That matters even more when the same lab touches CZI, ND2, SVS, TIFF, and DICOM across different projects.

SlideScope is designed around that review workflow. If you want to compare format-specific fit before you download, use the dedicated CZI viewer, ND2 viewer, SVS viewer, TIFF viewer, and DICOM viewer pages, or the guides for VSI, OIB and OIR, LSM, ZVI, LOF and XLEF, DeltaVision, MetaMorph, OME-Zarr, and NDPIS files.

Quick answers about SlideScope as a microscopy viewer

Best fit: research labs, imaging cores, pathology review teams, educators, and students that work across more than one microscopy format.

Key strengths: support for CZI, ND2, SVS, DICOM, and TIFF, plus VSI, OIB, LSM, ZVI, LOF, DeltaVision, MetaMorph, and OME-Zarr since 1.10.0 and ICS, DM3/DM4, SIS, iSyntax, and KFB since 1.20.0; metadata review; calibrated measurements; TIFF export; shared-link loading; and one viewer across Windows and macOS.

Important limitation: SlideScope is built for practical image viewing and review rather than for every acquisition, archival, or laboratory information workflow.

Common questions

Which microscopy file formats can SlideScope open?

SlideScope can open CZI, ND2, SVS, DICOM, and TIFF microscopy files, Leica LIF, and whole slide scanner formats such as NDPI and MRXS. Since version 1.10.0 it also opens Olympus/Evident VSI, Olympus OIB and OIR, Zeiss ZVI and LSM, Leica LOF and XLEF, DeltaVision, MetaMorph STK and ND, Hamamatsu NDPIS, and OME-Zarr files, and since version 1.20.0 ICS/IDS, Gatan DM3/DM4, Olympus SIS, Philips iSyntax, and KFBio KFB files. That covers many of the viewing needs found in research labs, imaging cores, and pathology-adjacent teams.

Can SlideScope open remote microscopy files?

Yes. SlideScope can open supported files from local storage or directly from HTTP and HTTPS URLs, with smart local caching for large files. MRXS, VMS, and VMU slides and OME-Zarr folders open from local storage only.

Does SlideScope include measurements and metadata review?

Yes. The app includes calibrated measurements, metadata display, zoom and pan, plus slice navigation for Z-stacks and time series.
