Why Convert JPG to FITS file?

FITS (Flexible Image Transport System) is the standard image and data format used in astronomy and scientific research, storing pictures along with detailed metadata. Converting JPG to FITS is useful when you need to bring an image into astronomy software or a scientific workflow that specifically works with the FITS format.

This is a specialized, technical conversion aimed at scientific and research use rather than everyday needs. The result packages your image into a FITS file that astronomy tools and data pipelines can read. For general viewing and sharing, JPG is far more practical, so keep your original for regular use. Reach for FITS only when a scientific program or research workflow specifically requires it.
