Embed fonts
The option Embed fonts, embeds - or includes - the original fonts
of your documents in the PDF file. This way, other users will
always see the documents in their original fonts on their computer,
even if they don't have the particular font you used installed on their
computer.
Note that embedding fonts increases the file size of your output
documents.
Create PDF/A fully compliant files (Readiris Corporate)
This option generates PDF files that are suited for long-term
archiving. PDF/A stands for "Portable Document Format
Archivable". PDF/A files contain only what is strictly needed for
opening and viewing them.

per-page downloading from web servers. This option is useful when
accessing the documents you sent to the Cloud.
