Why convert AVIF to ICO?

AVIF files turn up when you save images from sites that serve it to save bandwidth, and from image tools that export it for the web. Encoding is slow and many editors, CMSs and operating systems cannot open it yet. Choose ICO for a website favicon or a Windows shortcut icon.

AVIF to ICO settings

Choose which icon sizes to embed. Non-square images are centred on a transparent square canvas. You can also cap the width and height, which resizes large photos in the same step.

Frequently asked questions

Will the ICO lose quality?

ICO is lossless, so the conversion keeps every pixel or sample that is in your AVIF file. It cannot bring back detail that AVIF compression already removed, and the ICO file will usually be larger.

Is transparency kept when converting AVIF to ICO?

Yes. ICO supports transparency, so transparent areas in your AVIF stay transparent.
