Free online OpenEXR→FITS converter. Fast, private, no sign-up.
Converting OpenEXR to FITS is one of those small tasks that should be instant and free — and here it is. Drop in your OpenEXR file (a .exr) and download a ready-to-use FITS file (a .fits) — no software to install, no account to create, and no watermark on the output.
OpenEXR 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.
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.
Most people convert OpenEXR to FITS for compatibility — a website, app or device insists on FITS, and OpenEXR simply won't open. FITS is widely supported, which makes it a dependable target. 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.
Typical uses: preparing assets for a website, attaching a file someone else can definitely open, or standardising a folder of mixed files into one format.
Privacy is the default here. Your OpenEXR 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.
