ICO is the Windows icon container, and the traditional format for a website’s favicon. Universal for its one job: favicons and Windows icons. GIF, by contrast, universal, and the only animated format that works everywhere.
How to convert ICO to GIF
- Add your ICO files. Drag them onto the box above, click to browse, or paste an image straight from your clipboard. You can add as many at once as you like.
- Adjust the settings if you need to. The defaults suit most images. GIF is lossless, so there is no quality setting to adjust.
- Download the GIF file. Each file gets its own download button as soon as it finishes, and you can pull the whole batch down as a single ZIP.
What changes when you convert ICO to GIF
Every format conversion involves trade-offs, and vague tools hide them. Here is exactly what happens to your image in this particular conversion.
- Transparency is preserved: both ICO and GIF carry a full alpha channel.
- GIF supports only 256 colours per image, so photographs are colour-reduced. We use a quality-tuned palette to keep the result as close as possible, but gradients and skin tones will band.
About ICO (Windows Icon)
ICO is the Windows icon container, and the traditional format for a website’s favicon.
Where you probably got it: Website favicons and Windows application icons.
Strengths
- Holds several sizes in one file so each context picks the sharpest
- The one favicon format every browser understands, including very old ones
- Supports transparency
Limitations
- Only useful for icons — sizes are capped at 256x256
- Not a general-purpose image format
- Awkward to create in most image editors
About GIF (Graphics Interchange Format)
GIF is a 256-colour format from 1987 that survives almost entirely because it animates and pastes anywhere.
Support: Universal, and the only animated format that works everywhere.
Strengths
- Animation that plays inline in email, chat and ancient software alike
- Single-colour transparency
- Understood by essentially every piece of software on earth
Limitations
- Hard limit of 256 colours per frame — photographs come out banded
- Very inefficient file sizes compared with modern formats
- Transparency is on/off only, so edges look jagged
Is it safe to convert ICO online?
Here, yes — and you can check rather than trust. Open your browser’s developer tools, switch to the Network tab and convert a ICO file: no request carrying your image is made. Disconnect from the internet after this page has loaded and the converter still works, which would be impossible if a server were doing the conversion.
That is worth verifying wherever you convert, because most online converters do upload, and ICO files are so often personal photos and documents people would not hand to a stranger. Once a file is on somebody else’s server you are relying on a privacy policy rather than on anything you can observe. We wrote up how to tell a safe converter from a risky one in more detail.
Frequently asked questions
How do I convert ICO to GIF?
Drag your ICO file onto the box above, or click it to browse. The conversion starts immediately in your browser and the GIF download appears within a second or two for most images. You can drop in a whole folder of files at once and download them together as a ZIP.
Are my ICO files uploaded to a server?
No. The conversion happens locally in your browser, so your files are never transmitted anywhere — the tool even works with the network disconnected once the page has loaded. That is also why there is no file size or file count limit: nothing costs us anything per conversion. The practical ceiling is your own device's memory, which on a phone means very large images may fail.
Will converting ICO to GIF reduce the quality?
No. Both ICO and GIF are lossless, so every pixel is preserved exactly.
What is the difference between ICO and GIF?
