Inside an ICO file

ICO is a container, not a single image. It bundles the same picture at several sizes, 16, 32, 48 and 256 pixels, so Windows can pick the sharpest one for each context, from taskbar to desktop shortcut. Each size here is stored as compressed PNG data.

What happens when you convert

Your AVIF image is resized to four standard icon sizes and packed into one .ico file, entirely in your browser. Use it as a favicon or application icon right away, no extra tools needed.

AVIF to ICO FAQs

What is an ICO file?
ICO is the Windows icon format. One ICO file holds the same image at several sizes, typically 16, 32, 48 and 256 pixels, so apps can pick the right one for each context.
What sizes are in the ICO I download?
This tool builds a multi-size ICO with 256, 48, 32 and 16 pixel versions of your image, each stored as compressed PNG data inside the ICO container.
Where are ICO files used?
Favicons for websites, Windows application icons, shortcuts and installer graphics. Most browsers also accept PNG favicons today, but ICO remains the safest universal choice.
Will my AVIF image stay sharp as an icon?
Start with a square image at least 256 by 256 pixels for the crispest result. Very small sources get upscaled and can look blurry at the larger icon sizes.
Are my images uploaded to a server?
No. The conversion runs entirely in your browser with local code. Your files never leave your device.
