AVIF to ICO Converter

Turn an AVIF image into a real icon with every size inside - for PNG, JPG or SVG files use the Image to ICO converter.

How to convert AVIF to ICO

  1. Add your AVIF files. Drop up to 30 AVIF images into the box, or browse for them. They are decoded on your device and never uploaded.
  2. Pick the icon sizes. Recommended packs 16, 32, 48, 64, 128 and 256 px into one ICO. Favicon and Windows app are one click away, or type your own sizes.
  3. Fine-tune the look. Crop to square, add padding, round the corners or set a background colour. Every option shows its value at a glance.
  4. Make the ICO and download. Press Make my ICO. One or two icons download directly, more come as a ZIP.

Why turn an AVIF into an ICO?

AVIF is one of the smallest image formats on the web, but Windows cannot use it for program, folder or shortcut icons.

Many sites now serve pictures as AVIF, so a saved logo or sticker often lands on your disk in this format.

An ICO holds the same picture at several sizes, so it stays sharp from the taskbar to the Start menu.

Which icon sizes do you need?

Not sure? Keep Recommended - it covers every place Windows and browsers look. The Icons Analyzer lists every size inside an existing ICO.

What about HDR, 10-bit and animated AVIF?

  • 10 and 12-bit AVIF - your browser maps them to 8 bits per channel, which is all an icon can hold.
  • HDR photos - colours are toned for normal screens, so very bright areas can look a little flatter.
  • Transparent AVIF - the see-through background is kept in every icon size.
  • Animated AVIF - every frame shows up under the preview, so you can pick the one you like.

The AVIF is decoded by your browser. Chrome, Edge, Firefox and Safari 16.4 or newer all can - on an older browser you get a short note telling you what to do.

Tips for great icons

  • Start big. 256 x 256 px or larger gives the sharpest large icon. Small source? Try the Image Upscaler first.
  • Not square? Pick Crop to square to fill the icon, or keep Fit inside for transparent bars.
  • Just need a normal picture? AVIF to PNG keeps transparency and opens everywhere.
  • Need a different size later? The Icon Resizer adds or removes sizes in an existing ICO.
