How do I convert JFIF to ICO?

Does converting JFIF to ICO lose quality?

Each icon size is scaled down from your image and stored without further compression, so small sizes stay crisp.

JFIF or ICO: which should I use?

Use JFIF for nothing a JPG can't do — it holds the same image data. Use ICO for website favicons and Windows app or shortcut icons. Keep in mind the main drawback of ICO: icons are square and at most 256 × 256 pixels.

A .jfif file is a JPEG with an unusual extension; Windows and some browsers save web images this way. The picture is identical to a .jpg, but many sites and apps refuse the .jfif name.

What sizes does the ICO file include?

The standard icon sizes of 16, 32, 48, 64, 128 and 256 pixels, skipping any larger than your image. Browsers and Windows pick the best size automatically.

Is the JFIF to ICO converter free?
