GIF to ICO Converter

What GIF to ICO conversion does

Convert a GIF to a Windows ICO icon directly in your browser, turning the GIF's opening frame into a single size or the default multi-size package covering 16, 32, 48, 64, 128, and 256 px in one .ico file.

How to convert GIF to ICO

1. Choose a GIF file.
2. Pick a single icon size, or leave the default multi-size package selected.
3. Select Convert & download.
4. Save the .ico file from your browser downloads.

Why use this conversion

Turning an animated GIF's opening frame into a static favicon or app icon is one of the most natural reasons to use this converter specifically — icons are static by nature, so losing the rest of the animation costs nothing for this use case, and ICO is the format Windows expects for application icons, shortcuts, and favicons.

Transparency and output quality

Each embedded size keeps the alpha channel from the GIF's first frame — this is a real ICO container (ICONDIR plus one entry per size), with each size embedded as genuine PNG-compressed image data, not a renamed bitmap. Because GIF transparency was already a hard 1-bit mask, there's no extra alpha detail to gain here, just a faithful PNG-compressed copy of it. Each icon entry uses PNG compression, so a single-size ICO stays small; the multi-size package is larger since it bundles six images generated from that same first frame.

Privacy and local processing

• Processing occurs locally in the browser.
• Files are not uploaded to Looty Tools for conversion.
• Converted files remain on your device.

Limits and known issues

• Input: GIF (.gif) only, up to 25.0 MB and 8,192 px per side.
• Each icon size is generated by resizing the full image to a square canvas, so a non-square source frame will be stretched to fit.
• Only the GIF's first frame becomes the icon — if your GIF loops through several distinct images and you want a different moment represented, extract that specific frame elsewhere first, since this tool always takes the opening frame.
• Metadata is not preserved in the downloaded file.

GIF to ICO FAQ

Why convert GIF to ICO?

The most common reason is turning an animated GIF's opening frame into a static favicon or app icon — icons can't animate anyway, so this converter's first-frame behavior fits the use case naturally. ICO is the format Windows expects for application icons, desktop shortcuts, and favicons.

Can I generate a multi-size ICO?

Yes. The ICO output defaults to a multi-size package covering 16, 32, 48, 64, 128, and 256 px, or you can pick a single size from the dropdown.

Is this a real ICO file, or a renamed image?

A real ICO container (ICONDIR plus one entry per size), with each size embedded as genuine PNG-compressed image data taken from the GIF's first frame.

Does this keep the GIF's animation?

No — icons are static, and so is this tool's output. Only the GIF's opening frame is captured into the ICO; any later frames, their timing, and the loop are never part of the icon.

Are my files uploaded?

No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.

What is validated before conversion?

The file must actually be a GIF — the tool checks the GIF87a/GIF89a signature bytes, not just the filename or extension, before decoding.
