What happens, and why

JPG is the lossy compression format for photographs. It opens everywhere and cannot store a transparent background. Cameras, Android phones and most websites save in it. ICO is the format for Windows icons and website favicons. It holds several small sizes, such as 16, 32, 48 and 256 px, in one file.

A favicon ICO should hold four sizes, 16, 32, 48 and 256 px, in one file so browsers and Windows each pick the one they need. A picture that is not square is padded with transparency.

The file is opened and converted inside this browser and never sent to a server. The image is redrawn at four sizes and packed into one file. Camera metadata (EXIF) is not carried over, so no location data remains in the result. You can add several files at once.

FAQ

3
Does the quality get worse

The image is redrawn at icon sizes, so the pixels differ from the source. For a favicon that is what is wanted.

Can I convert several files at once

Yes. Add them together and they are converted in order, each with its own download.

Where does my file go

Nowhere. The conversion finishes inside this browser, and camera metadata (EXIF, location) is not carried into the result.
