Free AVIF to ICO converter

Why convert AVIF to ICO?

People convert AVIF to ICO because AVIF makes remarkably small files, but older browsers, phones and photo editors still throw an error when they meet one, while ICO is what Windows icons and browser favicons actually require.

How to convert AVIF to ICO

1. Choose your AVIF file. Drop it on the box above, or tap to browse. You can pick several files at once.
2. Confirm the target is .ico. It is preselected when your browser can encode it; otherwise the closest available target is chosen. Adjust quality, size or the other options if you want to.
3. Convert and download. Press Convert, then Download. Your file stays on your device the whole time.

What is a .avif file?

AVIF uses the AV1 video codec to compress still images, often landing at half the size of an equivalent JPG. Browsers display it well; most desktop software does not yet. Use it for pages you build, and convert it to JPG or PNG for anything you need to send to another person.

What is a .ico file?

ICO is the Windows icon container, used for favicons and application icons. One file can hold the same image at several sizes so the system can pick the right one; 16, 32, 48 and 256 pixels are the usual set.

What to expect from this conversion

The target format is lossless, so every pixel of the decoded image is preserved exactly. The result can be larger than the original, which is the normal trade for keeping full quality. Windows icons are capped at 256×256, so a larger picture is scaled down to fit.

Is it private?

Yes, by design. Every conversion happens inside your own browser using your device’s processor — there is no server that receives your AVIF file, so there is nothing for anyone to store, scan or leak. You can confirm it yourself: open your browser’s developer tools, watch the Network tab while you convert, and you will see no upload.
