Hi All,

There's a VBO on the DX for this.

Hi @ewilson. I want to reduce file size of PDF. The output format should be PDF only. By using above VBO, I can just compress into Zip.
I Found a solution for that. There is an option in Adobe reader to reduce size file, which I was able to automate PDF Reader using global send keys.
I was looking for any code for that without depending on any application.

Thanks

Hi Vinod,

you might need to make use of external libraries to achieve what you are trying to do iTexSharp is a good library but compression ratio is less

SPIRE.pdf is a good one you can get the dll from here https://www.nuget.org/packages/Spire.PDF/ and examples are available in https://www.e-iceblue.com/Tutorials/Spire.PDF/Spire.PDF-Program-Guide/Document-Operation/How-to-Compress-PDF-Document-in-C-VB.NET.html

do it on your own risk 🙂 sometimes we will have to think out side of the box to get what is needed

Hi Jerin.
By using ITextsharp, I think after compressing file output will be in Zip format not into pdf format. I found Spire.pdf at early stages, but I am looking for any code or VBO internally.
If I couldn't able to find anything then I will go with Spire.pdf

Thanks for the response.

Ok, Adobe's PDF Services supports compression of the PDF. The Blue Prism PDF Toolkit, available on the Digital Exchange, includes an action for this feature. However, there's a cost associated with using Adobe's Document Cloud. You can trial it for free, but eventually you'll have to start paying.

I'm not aware of any free/open source libraries that implement PDF compression.

There is a utility available online called Ghostscript. I've seen some articles that state it can be used to compress a PDF, but this seems to be hit-or-miss depending on the content of the PDF. You can find Ghostscript here. It is open source and there is a Windows version.

Then you can take a look at this page on GitHub for an example of the command line parameters you'd need to pass into it.

NOTE: I have NOT tested this myself. Tread cautiously.

@vinod chinthakindi,
