Size PDF

Hi Henri,

where's the file?
The 37 kb image won't be the only one inside...
Some hidden embedded inside should be there.
If i can have a look... i can tell more ;-)

Cheers,
Ingo

Usually each separate font it is about 300Kbytes or even more.

But in your case you have 13 dfferent, embeded font.
And for example one of them is using 939280 bytes.

btw.
I use https://www.winking.be/products/pdfanalyzer

to analyze yours PDF.

Hi Henri,

you should open your pdf with notepad to analyze by yourself (it's very easy).
Each embedded fontfile was inserted as stream.
Before each stream you'll find the size in bytes.

In your case try to search with...
/FontFile2
Besides this search string you'll find the object position for example:
/FontFile2 9 0 R
This means object 9 0.
If you try to search backwards to the beginning of object 9 0 you'll find this:
9 0 obj
<<
/Length 806504
/Length1 806504
>>
stream
...
This means that the first embedded font content has a stream length of 806504 bytes.

Go on searching you'll find the next object here:
/FontFile2 13 0 R
Searching backwards with 13 0 you'll find this:
13 0 obj
<<
/Length 111108
/Length1 111108
>>
stream
...
So the second embedded stream has a size of 111108 bytes.

At the end you've found 10 streams - each stream with a content size range from 100 kb up to 910 kb. These fonts are resulting in the large file size. Cause these embedded fonts are standard fonts and no special ones you should change to referenced fonts to have a small handy and fast loading file.

Cheers,
Ingo

installed the program you suggested,but i got only 3 fonts embedded in the pdf..

You have about 10 fonts not 3.
I see you already check @Ingo explanation (how to check it with NotePad) and I try to do the same explanation with PDFAnalyzer.

even 13 fonts dont make 8 mb ? But I cant figure out what changed the size eventually

The screenshot which I post to you cleary indicates that this specific fonts takes alomst 1MB size !!!

So why you was suprised that 13 or 10 fonts can make 8 MB ?
Did you not notcie the length of specific fonts from the screenshot ?

btw.
Thanks Ingo for the tip with checking in notepad.
