How do I convert AVIF to ICO?

Upload your AVIF file above. It is converted to ICO automatically (change the output format or quality in the Settings tab if you need to), then click Download. There is nothing to install.

Does converting AVIF to ICO lose quality?

Each icon size is scaled down from your image and stored without further compression, so small sizes stay crisp.

Will the ICO keep the transparent background?

Yes. ICO supports smooth, partial transparency, so transparent areas stay transparent.

AVIF compresses still images with the AV1 video codec. It usually produces smaller files than JPG and WebP at the same visual quality and supports HDR and transparency.

What sizes does the ICO file include?

The standard icon sizes of 16, 32, 48, 64, 128 and 256 pixels, skipping any larger than your image. Browsers and Windows pick the best size automatically.

Is the AVIF to ICO converter free?

Why convert AVIF to ICO?

Transparent areas stay transparent: ICO supports smooth, partial transparency just like AVIF.
One ICO bundles the standard 16 to 256 px icon sizes (up to the size of your image), ready for a favicon.ico or a Windows shortcut.

What to expect when converting AVIF to ICO

Icons are square, so a non-square image is centred on a transparent square. Sizes larger than your image aren’t created, so start from at least 256 × 256 pixels.
Your original AVIF file isn’t changed: you download a new ICO copy.
