Why Convert FITS to PNG file?

FITS (Flexible Image Transport System) is the standard image format used in astronomy and scientific research, which ordinary programs cannot open. Converting FITS to PNG turns a scientific image into a standard, lossless picture that opens in every viewer, editor, browser, and app, so you can view or share it like a normal image.

PNG is lossless and universally supported, so a FITS image becomes viewable on any device with detail intact. This is useful when you want to see or share an astronomical or scientific image without specialized software. Keep the FITS file for scientific analysis, since it holds the underlying data, and use PNG when you simply need a viewable picture.
