File extension .FITS
CategoryImage File
DescriptionThe Flexible Image Transport System (FITS) is a widely used format for astronomical data storage and interchange. It was first developed in the late 1970s and has been updated over the years to keep pace with changing technology and scientific requirements.

FITS files contain both image and metadata information in a flexible, self-describing format that is platform-independent. This means that data can be easily shared and analyzed across different computer systems and software programs.

FITS files are commonly used to store data from ground-based telescopes, space observatories, and other astronomical instruments. They can also be used for simulations and other scientific applications.

FITS files can contain a wide range of information, including spectral data, time-series data, and multi-dimensional data cubes. They are widely supported by astronomical software packages, including image processing software and data analysis tools.

In summary, the FITS format provides a flexible and powerful way to store and share astronomical data. Its continued development and widespread adoption ensure that it will remain an important tool for astronomers and other scientists for years to come.

JPG File

File extension .JPG, .JPEG, .JPE, .JFIF, .JFI
CategoryImage File
DescriptionJPG is the file format for images made by digital cameras and spread throughout the world wide web. Saving in JPG format an image loses its quality, because of the size compression. But at the end you have a much smaller file easy to archive, send, and publish in the web. These are the cases when an image's size matters more than image's quality. Nonetheless, by using professional software you can select the compression degree and so affect the image's quality.

Online FITS to JPG conversion

Why Convert?

FITS files are highly specialized and are primarily used in the fields of astronomy and astrophysics. While they contain a wealth of information, their specialized nature makes them less accessible for general use or public sharing. JPG files, on the other hand, are universally recognized and can be easily shared and viewed.

Tools for Conversion

Python Code Example using Astropy

        from astropy.io import fits
        import matplotlib.pyplot as plt
        # Read FITS file
        hdul = fits.open('example.fits')
        # Access the primary data
        data = hdul[0].data
        # Close the FITS file
        # Plot using matplotlib and save as JPG
        plt.imshow(data, cmap='gray')


Converting FITS to JPG makes the data more accessible and easier to share. There are various tools and libraries available that can help you do this in a straightforward manner.

Is it safe to convert FITS to JPG Online?

Our tool converts an uploaded copy of your original file. The original file stays on your computer and is unaffected by the process. There is no risk of data loss by conversion.

Also, your data is safe with us. We delete all uploads from our servers after one hour. In other words, an hour after you upload your files, those files are purged from our servers forever. You don't need to worry about your content being stored on the server.
