TIFF-based microscopy format for multidimensional images and OME-XML metadata
File type:
OME-TIFF is a TIFF-based image format designed for scientific microscopy. It stores image pixels together with OME-XML metadata describing dimensions such as width, height, channels, depth, time points, physical resolution, and acquisition information.
Files can be opened with Fiji or ImageJ using the Bio-Formats importer. Other compatible applications include QuPath, OMERO, and software that supports the Bio-Formats library.

OME-TIFF combines the broadly supported TIFF container with the Open Microscopy Environment (OME) data model. The OME-XML metadata is commonly embedded in the TIFF description field, while pixel data may be distributed across multiple TIFF pages or files. This structure allows a single dataset to represent multidimensional images, including Z-stacks, time series, channels, and image series.
OME-TIFF is intended to preserve scientific image information that a conventional TIFF may not describe consistently. Metadata can include channel names, color information, physical pixel sizes, stage positions, acquisition dates, instrument details, and relationships between image planes. Large datasets may use tiled storage, compression, BigTIFF, or companion files in a multi-file OME-TIFF arrangement.
The format is associated with the OME specification and is commonly produced by scientific cameras, microscopy systems, image-management platforms, and conversion utilities. The exact metadata and compression options vary by application, so compatibility may depend on the version of the OME model and the TIFF features used.
Fiji, ImageJ, and Bio-Formats provide broad support on Windows, macOS, and Linux. QuPath can open many OME-TIFF images for digital pathology workflows, while OMERO can import and manage them on supported server installations. Basic TIFF viewers may display some pixel data but may ignore multidimensional organization or OME metadata.
On Windows, macOS, or Linux, install Fiji and choose File > Open, or use the Bio-Formats importer when prompted. Fiji is generally the safest choice for preserving and navigating channels, Z-slices, and time points. QuPath is another option for supported whole-slide or microscopy images.
For server-based analysis, upload the image to an OMERO installation that supports OME-TIFF. If a desktop viewer reports that the file is invalid, confirm that all companion files are present when the dataset uses a multi-file layout, and try a current version of Bio-Formats.
For desktop conversion, use the Bio-Formats command-line utility bfconvert or Fiji's Bio-Formats export tools. These can convert OME-TIFF to formats such as standard TIFF, BigTIFF, JPEG, PNG, or OME-Zarr, depending on the selected options and whether the target format can preserve multidimensional data and metadata. Python users can also use libraries such as tifffile for controlled scientific workflows.
Online converters may accept small, ordinary TIFF images, but they often remove OME-XML metadata, do not support multi-file datasets, or impose upload-size limits. For research data, a desktop or command-line converter is preferable; keep an untouched original and verify the converted file's dimensions, channel information, resolution, and metadata before deleting the source.
