•Select Unembed all fonts to unembed all fonts. This will reduce the size of files as far as possible with regard to fonts. However, it also increases the risk of compatibility issues for subsequent users of the document. This is because they will not be able to read the document unless the application they are using to view the document contains the font. Therefore this setting should be used only in cases where documents contain only common fonts.
