Convert OIR to another file type

To convert OIR confocal images to another format, you need Olympus FLUOVIEW or other Camera Raw software.

Convert a file to OIR

To convert other file formats to the "Confocal Microscope Image File" file type, you need software like Olympus FLUOVIEW or a similar tool.


About OIR files

The .OIR file is a proprietary Olympus raw image format used exclusively by Olympus FLUOVIEW confocal microscopes, such as the FV3000 series. These files store raw, uncompressed optical data, capturing high-resolution, multi-dimensional structures including Z-stacks, time-lapses, and multi-channel fluorescence. They are typically accessed using Olympus FLUOVIEW software or scientific open-source platforms like ImageJ using the Bio-Formats plugin.

Working with .OIR files presents significant challenges. Because it is a proprietary format, the files are unsupported by standard operating systems, web browsers, or conventional image viewers. They require expensive, specialized software to open and often exceed gigabytes in size, making them difficult to share or publish.

To make this data accessible, researchers must convert .OIR files. The best target format for preserving raw scientific metadata, spatial resolution, and dynamic range is .OME-TIFF or a standard TIFF stack. For presentations, emails, or web publishing, converting to JPG or PNG is useful, though this completely flattens multi-dimensional data and permanently strips away quantitative scientific metadata.

This file format is exceptionally difficult to open or convert because it is a closed, proprietary format containing complex multi-dimensional datasets. Standard online converters simply fail to process it because they lack the specific bio-imaging libraries required to decode the raw sensor arrays. Often, only the original software can properly read or export the full scope of the data. However, convert.guru can still identify the file format, inspect the file, and show text or internal content. If our analysis detects a supported underlying or embedded format, viewing or conversion may still be possible. Just drag and drop your file to identify the format, view it, and convert it when possible.

Convert.Guru analyzes your OIR file, detects the exact format, and lets you read the text inside.

Users also converted ORI, CZI, JSX, ZIP, DB, TXT, OIF, ND2, JPEG and TIFF files.


FAQ

If you want to convert OIR file to TIFF, JPG, PDF, PNG, GIF, BMP, TIF, WEBP, ICO, CUR, PSD or PSB, you can use Olympus FLUOVIEW or similar software from the "Confocal Microscope Image Storage" category. In the File menu, look for Save As… or Export….

To convert RAW, PNG, AI, NEF, PSB, DNG, SVG, GIF, EPS, JPG, ARW or PDF files to OIR, try Olympus FLUOVIEW or another comparable tool in the "Confocal Microscope Image Storage" category.



The OIR Converter Story

The history of Convert.Guru began over 25 years ago in California with Tom Simondi’s file-format database. A former contributor to Space Shuttle development and a software pioneer of the 1980s, Simondi established a trusted resource for file type analysis that was even referenced by Microsoft Windows XP. Today, we use modern technology to process and convert thousands of file formats while continually improving our OIR converter.
