how to find why a pdf is so big in pdfdebugger

Hey guys,

I have a pdf with one page that have some texts and a 71kb image,
How could be that this pdf has 1337 kb ?

I'd like to find what objects are bloating the size of this pdf in
PDFDebugger but I couldn't find a way to check on that.
I was hoping if you could give me some tips.

This pdf is actually one page extracted from a 22 pages pdf, and the
original file (with 22 pages) has 1345 kb, 
so I'm guessing that for some reason this page is holding references from
all the resources of the original pdf.
And I'd like to be sure of that, is there a way through pdfDebugger to check
this?


Thanks.
José Freitas.

Hi Mehdi,

I'll try to get permission to show this pdf.
Btw, how can I ask for pdfbox to save using flating compression?

Thanks.

Hi Jose,

There are several factors that could affect the size of a PDF, one
factor we found that made a significant difference was accessibility
features within a PDF. These are features that assist text-to-audio
clients for the visually impaired and there will be a structure tree
in the PDF if it does have accessibility features. Another factor is
the compression, if your PDF isn't compressed with a Flate encoder,
that also makes big impact on file size. However, without seeing the
PDF, we can only speculate.

Hope that helps

Mehdi

RES: how to find why a pdf is so big in pdfdebugger

Posted by José Rodolfo Carrijo de Freitas <jo...@softplan.com.br>.

Hi Eric,

1) I'd like to, but I don't know what to say to be more specific,
2) I believe I cannot publicize the pdf since it's a document from a judge
court.
3) Basically, I list all the pages from a pdf and iterate over them, saving
them separatedly in a pdf with pdfWithOnePage.addPage() and
pdfWithOnePage.save(..)

My problem is that I need to find why a pdf is so big (1337kb), what could
possible make a pdf bigger? I can only think on resources, like images, and
this pdf has only one image with 71kb.

Can you be more specific?
Do you have test samples?
How did you extract the page?
