What is AVIF format and why convert to ICO?

AVIF is a modern image format with excellent compression, but browsers and operating systems require ICO format for favicons and icons. Converting AVIF to ICO allows you to use modern images as website favicons and application icons.

How many sizes should I include in my ICO file?

For website favicons, include at least 16x16, 32x32, and 48x48 pixels. For Windows application icons, also add 64x64, 128x128, and 256x256 for high-DPI displays and large icon views.

Will my ICO file work in all browsers?

Yes, ICO format is universally supported across all major browsers including Chrome, Firefox, Safari, and Edge. The multi-size embedding ensures optimal display at any resolution.

What happens to transparency in AVIF files?

Transparency is preserved when converting AVIF to ICO. The tool uses PNG compression inside the ICO file, which fully supports alpha transparency for smooth edges and transparent backgrounds.

Is the AVIF to ICO conversion completely free?

Yes, our AVIF to ICO converter is completely free with no hidden costs, watermarks, or limitations. Convert as many images as you need without any registration or subscription requirements.

Are my images secure when using this converter?
