How to convert AVIF to ICO
- Choose or drop your AVIF files above.
- Keep the default sizes (16, 32, 48 and 256 pixels) or pick your own.
- Download the .ico file and use it as a favicon or a Windows icon.
Why convert AVIF to ICO?
AVIF gives very small image files, but it is not a format that Windows, desktop shortcuts or older browsers accept as an icon. ICO is the format they expect. If your logo was exported as AVIF, converting it is the quickest way to get a working icon without opening a design app.
What you get
- One .ico file per AVIF image, with every size you ticked inside it.
- Transparency kept, so rounded logos and cut-out shapes look right on any background.
- No quality loss beyond resizing, because each size is drawn from the full original.
Browser support for AVIF
The tool opens AVIF using your browser, so it needs a recent version of Chrome, Edge, Firefox or Safari. If a file will not open, update your browser or convert the image to PNG first. Animated AVIF files use their first frame.
Using the icon on a website
Save the file as favicon.ico, upload it to the root folder of your site and link it from your pages. The PNG to ICO converter page explains the favicon steps in detail. If you only have a bigger photo, shrink it first with the image resizer.
Choosing icon sizes
For a website favicon, 16, 32 and 48 pixels are enough. Add 64, 128 and 256 pixels if the icon will also appear on a desktop or in Windows Explorer, where bigger sizes are used. Every extra size makes the file a little larger, but an ICO with all sizes is still usually under 200KB.
Square images work best. If yours is not square, choose whether to keep the whole picture with transparent padding or to crop it to a square.
Frequently asked questions
Why will my AVIF file not open?
Your browser may be too old to decode AVIF, or the file may be damaged. Update the browser, or convert the image to PNG in another app first.
Can I turn a photo into an icon?
Yes, but icons work best with simple, high-contrast pictures. At 16 pixels, small details in photos become a blur.
Is the AVIF uploaded anywhere?
No. Decoding and icon creation both happen in your browser, so the image stays on your device.
