Extract text from MIRAX virtual slides (MRXS)
To convert MRXS virtual slides to another format, you need 3DHISTECH CaseViewer or other Raster Image software.
To convert other file formats to the "Virtual Slide Image" file type, you need software like 3DHISTECH CaseViewer or a similar tool.
The .MRXS file format stores high-resolution digital slide images produced by 3DHISTECH Pannoramic Scanners and legacy Carl Zeiss MIRAX scanners. These files are used in digital pathology and medical research to store "virtual slides" that allow users to view microscopic tissue samples at various magnifications.
To open a .MRXS file natively, you must use specialized software like 3DHISTECH CaseViewer or open-source digital pathology platforms like QuPath and OpenSlide.
The main disadvantage of the .MRXS format is its proprietary, multi-part structure. The actual .MRXS file is typically just a small index document. The heavy image data - stored as thousands of pyramidal JFIF or JPEG tiles - resides in a separate data folder with a matching name. Because of this index-plus-folder design, the format is highly restrictive. Total datasets frequently exceed several gigabytes, making them impossible to open in standard web browsers or generic image editors like Adobe Photoshop.
If you need to share these images outside of specialized medical software, conversion is mandatory. The best target format for digital pathology interoperability is .OME-TIFF, which retains the complex pyramidal image structure. For reports or presentations, users typically export specific zoomed-in regions as standard JPG or PNG images.
This file format is difficult to open or convert online because standard cloud converters only expect single-file uploads, not a linked directory of thousands of image tiles. Often only the original software can properly read or export the full spatial data.
Convert.Guru analyzes your MRXS file, detects the exact format, and lets you read the text inside.
Users also converted JPG, DAT, SVS, ZIP, JPEG, FCSTD, TIFF and DICOM files.
If you want to convert MRXS file to SVS, TIFF, DICOM, JPG, PDF, PNG, GIF, BMP, TIF, WEBP, ICO or CUR, you can use 3DHISTECH CaseViewer or similar software from the "Digital Pathology Whole-Slide Imaging" 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 MRXS, try 3DHISTECH CaseViewer or another comparable tool in the "Digital Pathology Whole-Slide Imaging" category.
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 MRXS converter.
