ICO to GIF converter
This makes a GIF out of the ICO you already have. ICO is the icon file that Windows and browsers use, and it holds several sizes of the same picture in one file so nothing ever has to be stretched. Your file never leaves your computer.

How to convert ICO to GIF
- 1 Drop your ICO .ico file onto the page, or click to browse for it.
- 2 Check the options. Nothing is thrown away on the way to GIF, so there is no quality dial to set.
- 3 Convert. The work happens on your own machine, so how long it takes depends on your computer and the file.
- 4 Download the GIF, or add more files and do the whole set in one go.
Why convert ICO to GIF
- Animation plays everywhere with no player or plugin needed.
- Flat colours stay crisp, with nothing smudged around the edges.
- Animated content for platforms that will not accept video.
- ICO: each picture inside it is capped at a small size.

Quality and what changes
GIF stores the same content under a different set of rules, so what matters here is compatibility rather than picture quality. Convert once from the best source you have rather than through a chain of intermediate files.
- A multi-page ICO produces one GIF per page.
- One GIF limitation to keep in mind: only 256 colours per frame, which wrecks photos and smooth gradients.
Questions about ICO to GIF
Why does the GIF look grainy or banded?
GIF allows only 256 colours per frame. Photographic content, gradients and skin tones cannot be represented exactly, so the encoder dithers, which reads as speckle. Flat graphic content survives the palette far better than filmed footage.
What happens to a multi-page ICO?
GIF holds one page, so each page becomes a separate file and you get the set as a ZIP. Nothing is discarded, it just cannot stay in a single document.
Is my ICO file uploaded anywhere?
No. The whole thing runs inside the browser tab you already have open. Your ICO is read straight from your own disk, converted on your machine and handed back as a GIF. Nothing is sent anywhere, nothing is stored and there is no account.
Is there a file size limit?
There is no server-side limit because no server sees the file. The real ceiling is your device memory, since the input and the output both have to fit in the tab. A few hundred megabytes is usually fine on a desktop machine and considerably less on a phone.
Can I convert several ICO files at once?
Yes. Add as many as you like and they are processed one after another, then offered as separate GIF downloads or as a single ZIP. Speed depends on your own processor rather than on a queue.
Does the converter work offline?
Yes, after the page has loaded once. The engine is cached by the browser, so you can disconnect, reload and keep converting. That falls out of doing the work locally rather than being a separate mode you switch on.
