Why Convert FITS to ZIP file?

Converting a FITS file to ZIP places your scientific image or data inside a compressed archive that every operating system can open. FITS is the standard format used in astronomy, and archiving it into ZIP is useful when you want to store, back up, or share it, or bundle several files together.

A ZIP is handy whenever an email or upload has size or file-count limits, or you simply want a compressed copy. Because FITS files can be large, zipping may meaningfully shrink them. Opening the ZIP restores the original FITS exactly, ready for astronomy software. For packaging and transferring scientific data files, ZIP is a convenient, universal choice.
