Why do the icons look stretched or fuzzy/pixelated?
All of the file types can look distorted if they’ve been stretched wider or taller than their normal dimensions. Most of the time, if an icon appears fuzzy or pixelated it’s because a PNG file type is being used. In rare cases, one of the other file types could appear to be fuzzy or pixelated.
