Free online FITS→SGI converter. Fast, private, no sign-up.
If something is asking you for a SGI file and all you have is a FITS, this page is the fix. Drop in your FITS file (a .fits) and download a ready-to-use SGI file (a .sgi) — no software to install, no account to create, and no watermark on the output.
FITS is an image format. Converting to or from it lets you use the same picture in apps and on platforms that expect a different format.
SGI is an image format. Converting to or from it lets you use the same picture in apps and on platforms that expect a different format.
You'll reach for a FITS to SGI conversion whenever the other end expects SGI specifically — uploading somewhere, importing into software, or sharing with someone whose device prefers it. Under the hood the conversion runs on libvips and ImageMagick — the same libraries that power image pipelines across the web — so colour, transparency and metadata are handled correctly wherever the target format supports them.
You might be optimising images for a faster-loading page, exporting for a specific app or marketplace, or just making sure a colleague on a different device can open what you send.
Privacy is the default here. Your FITS file is uploaded over an encrypted connection, converted, downloaded the moment it's ready, and then deleted automatically a short time afterwards. We never keep your files, never build a library of your content, and never make you sign up to download the result.
