Hi All,

I need to write a custom code in JAVA which should be capable of handling the compression of pdf files.

Any help would be highly appreciated.

Thanks

What do you mean by this? You mean you want to combine a bunch of PDFs into, say, a ZIP file?

No, I need to compress a pdf file. Lets say, I have a pdf file of 40KB and I want to eliminate the white space and compress the pdf file to 25KB or lesser. The input and output file are in same format i.e. pdf and are single page files. Can you please suggest me some pdflib available to achieve the same?

The output size of a file is controlled by many things - the PDF version you're saving as, the quality of the page contents, whether or not there is rich media contained in the document. However there is no general "make my PDF smaller" method.

Remember that PDF is a binary format. "Removing the whitespace" can (and in most cases will) break your PDF file.

This is very optimistic. If there was "white space" ready to be
removed, it would not have been added in the first place.

Is there a way to removed and compress the pdf?

What does you mean with "white space" ?

[kumar91000@adobeforums.com]

I don't know much about pdf but have heard that after removing the white spaces from pdf we can reduce the size of a pdf.

So Is there any program that can reduce the size of a pdf or I can use any lib to do that using java?

Thanks

Regarding the white spaces I read it on some site which I don't remember. But here what we are doing:

We are applying an overlay on the pdf and that overlay is in png format and our requirement is to compress the pdf output without compromising with quality.

Is there any solution for this?

>I don't know much about pdf but have heard that after removing the white spaces from pdf we can reduce the size of a pdf.

What kind of white space?

Do you mean - like a big picture which is mostly white, remove the
white parts of the picture?

Do you mean - remove extra blanks and new lines inside the PDF file?

Do you mean - something else?

Where did you hear about this? If it is a public web page, please give
a URL.

There are a variety of commercial solutions that you can call from a Java application that will reduce the size of a PDF document. Adobe's solution is part of the LiveCycle ES product suite.

I've had a lot of success with this product:

It claims to have a command-line interface, which you could probably call in your java code. I've only used it through the GUI, but got fantastic compression rates.
