PDF files contain metadata. Many file types contain metadata. This is everything from when the file was created to what application was used to create the file. In image files, you can even have GPS data and shutter speed data.
Some folks think this is a privacy concern - and it can be. You should clean the metadata from pictures when you're going to share them with a large audience and want to retain some privacy.
