Convert JPG to ICO — Quick Favicon
Need a quick favicon from a JPG? KoalaPic converts your image to a multi-resolution ICO file. Note that JPG lacks transparency, so the favicon will have an opaque background — PNG or SVG sources are preferred for favicons.

Why Convert JPG to ICO?
Sometimes you need a favicon fast and a JPG is all you have. While PNG or SVG are better source formats for favicons (due to transparency support), a JPG-sourced ICO works fine for solid-background icons.
How to Convert JPG to ICO
Upload a square JPG (or crop will be applied).
KoalaPic generates a multi-size ICO with standard favicon dimensions.
Download and deploy as favicon.ico.
Quality Note
JPG doesn't support transparency, so the favicon will have an opaque background. For favicons with transparent backgrounds, use a PNG or SVG source instead. Square JPG images produce the best results.
