Hi,

the reasons for big files generally are embedded fonts and images.

In forms with default fonts like Arial or Myriad Pro it doesn't make sense to embed the fonts as Reader/Acrobat have this fonts already and don't need it to be embedded.

Only Arial needs about 450KB in a form.

If you use images then don't embed them, because this means they get stored as base64-encoded string into the XML source instead of a flate-encoded stream into the PDF.

Base64 is very clumsy and needs more space.
