HTML2FPDF filesize of pdf is huge, why?

Freezer

If I use this code, it will generate a pdf file of about 760kb !!.

  $pdf= new HTML2FPDF();
  $pdf->Output("test1.pdf","F");
760kb !!!!!!!!

Because I didn't put any content in the pdf yet, I would expect a much smaller filesize. When I use fpdf instead of html2fpdf the filesize is only a few kb.

  $pdf= new FPDF();
  $pdf->Output("test2.pdf","F");
Only 1 kb!!.....

What's going on here?

That 760kB file
what does it look like, when you open it?
Is it all empty or what ?

There might be a bug in HTML2FPDF() that can not handle an empty request.
The programmer might have assumed always some input from HTML.
And forgotten the case when there is no contents.

You can test again, but put some very little contents ( like 'Hello World' )
and see if the output is still huge.

You might also consider the possibility that PDF's just weren't meant to be created from rendering HTML, and that in order to do so there is some (apparently sizable) overhead with the implementation of HTML2FPDF.

@:
the pdf file contains 1 blank page.

760kb is way too much overhead for a blank page if you ask me....

are there any ways of "analyzing" pdf's? what they actually consist of?

you can open it in a text editor, there is usually some readable material in there, not that i suspect it will help much. also check it in adobe see if it contains embedded fonts, they would blow the size out.
