FPR to FITS Conversion: FAQ

What are FPR files?

The FPR file format is associated with Fun Photor, a currently outdated image processing software program. An FPR file most likely contains an old image that was created or edited using this program. In case you found such a file on an old hard drive or received one by email, it's probably best to opt for converting it to a more accessible format, such as JPEG or PNG.

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.
