How to convert AVIF to ICO
- Choose or drop your AVIF files. You can add several at once.
- Check that “To” is set to ICO.
- Press “Convert to ICO” and download the results — or all of them as one ZIP.
AVIF vs ICO
AVIF — AV1 Image File. AVIF is a newer image format based on the AV1 video codec. It compresses even better than WebP, but support in editing software and older browsers is still patchy.
ICO — Windows icon. ICO is the icon format used for website favicons and Windows app icons. One .ico file holds the same picture at several sizes, so it looks crisp in a browser tab, on a taskbar and on a desktop.
Convert AVIF to ICO when you need a file for favicons and Windows icons. AVIF is better suited to very small, high-quality images on modern websites.
FAQ
5Are my files uploaded anywhere?
No. The conversion runs in your browser using your own device’s processor. Your files are never sent to a server, so nobody — including us — can see them. You can even disconnect from the internet after the page loads.
Will I lose quality?
The icon contains six sizes — 16, 32, 48, 64, 128 and 256 pixels — each stored as a PNG, so transparency is kept. Non-square images are centred on a transparent square rather than stretched. Start from a simple, high-contrast picture: fine detail disappears at 16 pixels.
Is there a file size or daily limit?
No limits, and no sign-up. Because nothing is uploaded, we don’t pay for your conversions and have no reason to cap them. Very large files are limited only by your device’s memory.
Can I convert many AVIF files at once?
Yes. Add as many files as you like; each is converted to ICO, and “Download all” saves them together as a ZIP.
Does it work on iPhone and Android?
Yes. It works in any modern browser — Safari, Chrome, Firefox or Edge — on phones, tablets and computers. Older or low-memory phones may be slower with very large files.
