I use vb6 for programming and my source code is:

Call PDFL.LoadFromFile(filedati, "")

DocID = PDFL.SelectedDocument()

'PDFL.RemoveDocument (docid)

totalpages = PDFL.PageCount()

Open fileguida For Input As #1

Do While Not EOF(1)

Line Input #1, recin

pippo = PDFL.ExtractFilePagesEx(filedati, “”, CurDir() & "\" & Trim((Mid(recin, 4))) & ".pdf", a & "-" & a + Mid(recin, 1, 3) - 1, 3)

If pippo = 0 Then MsgBox "Errore creazione singolo pdf pagina: " & a

a = a + Mid(recin, 1, 3)

Loop

Set PDFL = Nothing

Hi Nico,

you've made 4 pdf-files out of one.
These one file has perhaps one backgound-image, one truetype font-ressource, one top image on each page.
To make the look on now each single-page-pdf the same you have to multiply all ressources. This could be the reason for the new size multiplied by 4.
An assembly later won't remove the additional ressources. So you don't should use the normal merge. You'll find different functions here:

I am also facing the same issues like file size is 5 times more than the original file after extracting couple of pages from different documents and merging them back to single document.

But not able to find suitable function which will reduce the size after extract and merge.

Any suggestions will be appreciated.

Hi Krishna,

try the forum search (top,right) and then option "enhanced search" with "too large" ...
Then you'll get an idea what to do... what's possible and what's not possible.
It doesn't make sense to have many threads with identical content ;-)

Cheers and welcome here,
Ingo
