Brian Liu created PDFBOX-2690:
---------------------------------
Summary: Filesize becomes extremely large after saving
Key: PDFBOX-2690
URL: https://issues.apache.org/jira/browse/PDFBOX-2690
Project: PDFBox
Issue Type: Bug
Affects Versions: 1.8.8
Environment: PDFBox 1.8.8, Java8u25, Windows 8.1
Reporter: Brian Liu
I am using PDFBox 1.8.8 to manipulate existing PDF files. After saving a
document, the output file becomes several times larger than the original. This
is undesirable.
How to reproduce my problem:
========================
In the following code, PDFBox simply loads an existing PDF and then save it.
Nothing else is done. Yet the file size still becomes several times larger.
import java.io.*;
import org.apache.pdfbox.pdmodel.*;
import org.apache.pdfbox.exceptions.*;
class Test {
public static void main(String[] args) throws IOException,
COSVisitorException {
PDDocument document =
PDDocument.load("input1.pdf");document.save("output.pdf");
document.close();
}
}
Below are links to two sample input files. For input1.pdf, file size increases
from 6MB to 50MB. For input2.pdf, file size increases from 0.4MB to 1.3MB.

Possible reason
============
Tilman Hausherr suggests that there is an enormous amount of "structure"
information / object stream that is compressed in the input file, but not in
the output file.
