Removes embedded fonts from a document.
This can make the PDF lighter for internet distribution but risks messing up formatting if the font is not present on the end user's machine.
Optionally, you can choose not to execute this Action if the resulting font is unsafe.Embedding fonts in a PDF document means that every character of this font is copied and stored in the PDF document. This is useful if you create PDF documents to be displayed on different systems and to be printed on different devices: these are often systems that do not contain exactly the same fonts.
Embedding a font as a subset means that only those characters of the font that are actually used in the text are embedded. This reduces the file size by not including superfluous font information.
