What is a ICO file?
ICO is a container that holds one or more square icon images at different sizes. Browsers use it for favicon.ico and Windows uses it for application and shortcut icons. It is a lossless format best suited to website favicons and Windows application icons. The main drawback is that icons are limited to 256×256 pixels and must be square.
Frequently asked questions
Will the JPG lose quality?
JPG uses lossy compression, so some fine detail is discarded to make the file smaller. At the default quality setting the difference is very hard to see. Raise the quality slider if you need the result to stay closer to the ICO original.
Is transparency kept when converting ICO to JPG?
JPG cannot store transparency, so transparent areas are filled with a solid colour. White is used by default; you can pick any background colour in the options before converting.
