How to open QPTIFF files

Open Akoya QPTIFF whole-slide images in SlideScope on Windows or macOS without converting them. Pan and zoom across the full slide, measure in µm using the scanner’s calibration, and add annotations. Local viewing does not upload the image.

How to open QPTIFF files

  1. Download the Windows or Mac build, install it, and sign in with your free account.
  2. Drag the .qptiff file into the viewer or choose File › Open File… Open scanner slides from local storage.
  3. Use the overview to jump to a region, then zoom in. SlideScope loads the pyramid level that matches what is on screen.
  4. Check the pixel size (µm/px) in the file details before measuring, then measure, annotate and export the current view as an image.

When SlideScope is the practical choice

  • NDPI, VMS, VMU, MRXS, SCN, BIF, SVSLIDE, QPTIFF, and AVS scanner slides from Hamamatsu, 3DHISTECH, Leica, Ventana, Aperio, Vectra, and Agilent ARGOS
  • Reviewers need a desktop interface without scripting or plugin setup.
  • Step through channels, Z planes, time points and scenes where the file has them, check the pixel size in Details, and measure in calibrated units.
  • Measurements, notes and regions stay attached to the slide and export as GeoJSON or CSV.

Choose by workflow

Evaluate SlideScope when you need one desktop app that opens mixed microscopy files and quantifies standard objects on your own machine. Keep the original tool when you need microscope control, programmable image processing, scripted analysis pipelines, or institutional image management.

Fiji/ImageJ, QuPath, napari, CellProfiler: Extensible processing, macros, plugins, scripting, segmentation, batch measurement pipelines, pathology analysis, and scientific Python workflows.

OMERO: Centralized image repositories, permissions, collaboration, and institutional data management.

Questions about QPTIFF files

Opening QPTIFF slides on a Mac

SlideScope runs natively on macOS 14 or later, so you do not need a Windows PC or virtual machine for the vendor viewer. Choose the Apple Silicon or Intel download and copy the slide to local storage before opening it.

If the slide does not open

Confirm the whole file finished copying to local storage. If it still fails, contact support with the app version, file format and error message so we can investigate.

Who is it for?

It is built for research labs, microscopy core facilities, educators, students, and pathology review teams that need practical file review, annotations, measurements, metadata, and export.
