Why Convert FITS files?

FITS, or Flexible Image Transport System, is a file format primarily used in astronomy for storing and sharing scientific data and images. While it excels at preserving intricate details and metadata, its specialized nature can limit accessibility across various platforms and devices. Converting your FITS files to more universally recognized formats like JPEG or TIFF ensures that your astronomical images and data can be easily accessed and appreciated by a broader audience, including those who may not have specialized software to handle FITS files.

By transforming FITS files into formats that are widely supported, you enhance usability and convenience. This conversion allows for seamless sharing of your images and data with colleagues, clients, or the public, whether in presentations, reports, or on social media. Furthermore, using more common formats can reduce the risk of compatibility issues, ensuring that your visuals display correctly and maintain their quality across different devices and applications.
