Converting GIF to ICO produces a Windows icon file from a GIF source. The first frame becomes a static icon at standard Windows sizes. Useful for GIF-only legacy assets that need a favicon or desktop icon form.

Animation is lost; ICO is a static format. GIF's binary transparency transfers as proper alpha, but anti-aliased edges from the GIF may show color fringing due to the source's palette constraints. Start from large, high-quality GIFs for best results.
ICO is the standard Windows icon format and universal favicon format.
GIF is a 1987 format limited to a 256-color palette. Its lasting relevance is support for simple animation, which kept it in the meme ecosystem after PNG replaced it for static images. GIF compression is lossless within its palette constraints but usually worse than PNG for the same image.
ICO is the Windows icon format. A single .ico file can hold multiple resolutions (16×16, 32×32, 48×48, 256×256) and color depths simultaneously, letting the OS pick the best for context. Every browser serves favicons as ICO, and Windows desktop icons use it natively.
Lost. ICO is static. Only the first frame is used.
GIF's binary transparency maps to ICO's alpha channel, but edges that were anti-aliased in the GIF may look rough or show color halos.

Yes. The converter runs entirely in your browser using WebAssembly. Your images are never uploaded, never sent to a server, and never leave your device.
There's no hard limit, but because everything runs in your browser you're bounded by available memory. Very large images (over a few hundred megapixels) can hit browser memory limits. Process in smaller batches if you run into issues.
