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.

FAQ

SCT to FITS Conversion

What are SCT files?

The SCT or Scitex Continuous Tone (CT) format is associated with bitmap images created or edited on equipment produced by Scitex. The latter was an Israeli brand launched in the 1960s, serving the high-end printing and publishing industry. SCT files include grayscale or coloured images and tend to be very large and difficult to transfer and store.

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.
