What is AVIF to ICO Converter?
AVIF to ICO transforms AVIF images into ICO icon files. ICO stores multiple image sizes in one file for Windows application icons and browser favicons. The tool decodes the AVIF image, renders common icon sizes, and packages them into a single ICO output.
How does AVIF to ICO Converter work?
This tool reads your AVIF file using the browser's native image decoding, renders it to a canvas at standard icon sizes like 16x16, 32x32, and 48x48, and exports the result as an ICO file. AVIF supports transparency, which carries over into the ICO output for clean icon edges.

Frequently Asked Questions
Will the quality change?
ICO files are displayed at small sizes, so the image will be scaled down. Starting with a high-resolution AVIF ensures the icon looks sharp at all sizes.
Is my image uploaded to a server?
No. All processing happens in your browser using the Canvas API. The image never leaves your device.
What icon sizes are generated?
The tool generates standard sizes including 16x16, 32x32, 48x48, and 256x256 pixels, all packed into one ICO file.
Does the ICO preserve transparency?
Yes. Any transparent areas in the AVIF source are preserved in the ICO output for clean icon edges.
Can I convert multiple images at once?
Yes. Upload multiple files and the tool generates an ICO for each one.
