Why Convert FITS to JPG file?

FITS is the standard format used in astronomy for storing telescope and observation data, but it requires specialized scientific software to open and view — not something you can glance at in a normal photo app. Converting to JPG renders the image data into a compressed picture that opens instantly on any device.

Basic visual data carries over, though FITS often stores extra scientific metadata — coordinates, exposure settings, calibration data — that has no equivalent in a standard JPG and won't be preserved.
