Free online ICO→SGI converter. Fast, private, no sign-up.
Converting ICO to SGI is one of those small tasks that should be instant and free — and here it is. Drop in your ICO file (a .ico) and download a ready-to-use SGI file (a .sgi) — no software to install, no account to create, and no watermark on the output.
ICO is the Windows icon format — it packs several small sizes into one file and is what browsers request as a favicon.
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.
Most people convert ICO to SGI for compatibility — a website, app or device insists on SGI, and ICO simply won't open. SGI 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.
SGI has no alpha channel, so any transparent areas in your ICO are flattened onto a solid background during conversion.
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 ICO 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.
