Without seeing that PDF (or at least one that reproduces the issue without any 
Sensitive Customer Data on it), we can still just guess, but now at least we 
can make an /educated/ guess.
 
1) The field in question is using a font that weighs in at some size remarkably 
similar to the difference in sizes between the "unformed" and "formed" files.
 
... And I just saw Leonard's comment, then went back and saw that you did 
indeed mention Elsie Dee (LCD, Life Cycle Designer, har har).  XFA-based forms 
are relatively unknown territory (to me at least).
 
/Defnitely/ need to see the PDFs.  Before & After, if you please.

Subject: [iText-questions] PDF Form size


Well, before I do that, let me give some background (I don't want to remove all 
the items out of the PDF because they are confidential).

However, I took a form from Word and used LiveCycle to convert it to PDF Form.  
I then went into the form and setup the proper field names so that I could 
insert values into those fields via iText.

The basic conversion of the saved LiveCycle form ends up being approximately 
350K in size.

I had coded all of the stamper, sets, etc to setup those form fields to their 
proper values without issue, however the file either remains slightly larger 
than the original, or it grows another 75K.  Today, I thought I would try to 
simply open the PDF, make a copy and be done.  This is the code to do this:

    public void processLetter2( String pdfLetter )
    {
        try
        {
            PdfReader reader = new PdfReader( pdfLetter + PDF );

            Document document = new Document( reader.getPageSizeWithRotation( 1 
) );

            //-- create a new file, removing the directory /letters from the 
file name
            String sub = StringUtils.substringAfterLast( pdfLetter, "letters/" 
);
            //sub += strDate;
            File file = new File( sub + PDF );

            PdfCopy writer = new PdfCopy( document, new FileOutputStream( file 
) );
            document.open();

            for( int i = 1; i < reader.getNumberOfPages() + 1; i++ )
            {
                writer.addPage( writer.getImportedPage( reader, i ) );
            }
            writer.setFullCompression();

            document.close();

        }
        catch( Exception e )
        {
            e.printStackTrace();
        }
    }

The amazing thing is, this resulted in files being approximately 30 to 70K in 
size.  I was stunned to say the least.  Now, this seems to remove all access to 
the form fields which of course is not what I want.  However, I thought, I will 
run through my original code with the stamper and set my fields to their 
appropriate values, and then just take the "newly created file" and run though 
the method shown above (hoping there was some odd magic occurring in the write).

However, this doesn't seem to do much of anything to the 3rd file's size 
whatsoever.  It seems as if the stamper is the issue here.  As soon as I use 
it, the file size cannot be shrunk.

Am I missing something here?

Thanks

Show us your PDF. We'll poke around and see what we can see. You might be 
building the
form inefficiently, in which case a code change on your end may produce similar 
results. 
Might not, too... but we can't tell unless we see a PDF.

Subject: [iText-questions] PDF Form size



Is there any way to reduce the size of these files? The file I'm generating 
winds up being
anywhere from 250 to 300K in size. I can open the file in Acrobat, and select 
Optimize, and
it shrinks it to ~32K. Does iText have a way to do this that I'm missing? I've 
set
writer.setFullCompression() and it helps, but only takes it from 300 to 
270K(ish). 

Thanks...
