"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."

NEO to FITS Conversion: FAQ

What are NEO files?

NEO is an archaic and rare file format associated with NeoChrome, a bitmap image processor created for Atari computers. This brand was very popular in the 1980s and early 1990s, being one of the first types of computers to address non-tech home users. NeoChrome was among the first image editing programs to use a graphical interface and also enjoyed a lot of popularity. The program has now been discontinued for over two decades, so opening NEO images might be difficult using regular image viewers.

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.
