Fileverses

Free AVIF to ICO converter

Convert AVIF to ICOfor a favicon or Windows icon.

Fileverses creates a PNG-based ICO file from a browser-decoded AVIF image, on your device. The export includes centered 16, 32, 48, and 256 pixel icons, which is useful for an explicit favicon or Windows-icon handoff—not for turning a detailed image into a universally polished icon.

About this converter

Free AVIF to ICO conversion, built for a real workflow.

AVIF is a modern compressed image format, while ICO is a Windows and favicon icon container. This converter decodes the AVIF in your browser and embeds transparent PNG images at 16, 32, 48, and 256 pixels in a Vista+ ICO file. Each size fits the source within a square with transparent padding instead of cropping it. The result can meet a specific ICO requirement, but the tool does not create every possible favicon asset, generate an HTML link tag, or guarantee support in software that only accepts older bitmap-based ICO entries.

How it works

Upload once.
Export ICO.

01

Add a clear AVIF image

Choose simple, high-contrast artwork that will still read at favicon size. The AVIF stays in your browser.

02

Keep ICO selected

ICO is preselected for a favicon or Windows icon file. The encoder creates four PNG-backed square entries.

03

Download and test

Test the ICO in the intended browser, shortcut, or Windows workflow and inspect the 16-pixel version before relying on it.

Made for real pipelines

One workspace.

Convert without uploading your assets. Switch outputs anytime — web, print, icons, and document targets from the same batch.

Good to know

Questions, answered.

Why convert AVIF to ICO?+

Convert when a website, Windows shortcut, or destination workflow specifically requests an ICO icon. Keep AVIF for modern image delivery; ICO is a multi-size icon container.

What sizes are inside the AVIF to ICO file?+

Fileverses embeds PNG images at 16, 32, 48, and 256 pixels in the ICO container. Check your target’s requirements because some favicon setups also ask for separate PNG or manifest assets.

Will every old program open this ICO file?+

Not necessarily. This encoder writes PNG-backed ICO entries intended for Vista+ ICO support. Test the downloaded file if the receiving software only accepts older bitmap-based icon data.

Does the converter crop my AVIF to make an ICO icon?+

No. It scales the decoded AVIF to fit inside each square icon and leaves transparent padding. A wide or tall image may look small at 16 pixels, so review it before use.

Does AVIF transparency survive ICO conversion?+

The ICO entries are PNG images, so existing transparent pixels can be retained. The converter does not make an opaque background transparent or replace it.

Does Fileverses send AVIF images to a server for ICO conversion?+

No. Fileverses creates the AVIF-to-ICO file in your browser, so the source image is not sent to a conversion server.
