"Security was our top concern when evaluating file conversion tools. reaConverter’s offline mode and role-based access controls let us lock it down for sensitive environments. No unexpected network calls or bloat — just clean, fast conversions. Even passed our pen-testing scans without a hitch."

MRF to FITS Conversion: FAQ

What are MRF files?

MRF is a rare type of raster image format also known as "Monochrome Recursive Format" or "Marks Russell format", from the name of its developer. MRF files are considered obsolete and opening them with regular image viewers might pose difficulties. For easier access, we recommend converting such files to more popular formats.

What are FITS files?

The FITS (Flexible Image Transport System) format is a standard format used particularly for storing, transferring and processing scientific images from fields such as astronomy. FITS was first launched as an open standard in the early 1980s and has gone through several subsequent upgrades. FITS files contain not just images, but also data related to photometry and spatial calibration, and information about the origin of the image. Similar formats include FIT and FTS.
