PDF compressor for DELPHI 2007

Need a PDF compressor that I can use from DELPHI 2007.

What is the best one out there?

UPDATE -开发者_高级运维--

By PDF compressor I mean some way to compress an existing PDF. I don’t need to create new PDF files.

The usage that I’ll do with it, simple, I have in my applications the possibility to associate a file to a product, an entity, equipment whatever, and if the file is a PDF I want to be able reduce its size.

There some tools that can do this with no need to actually zip the file, what would mean that to see it you would have to decompress(unzip), this tools jut reduce the size.

So a PDF compressor, or call it what you will, is just this.

If you need to create PDF from Delphi code, see this page in Delphi:about.

I'd like to add our Open Source SynPdf unit, working from Delphi 6 up to XE.

Arguably the best is the Acrobat family of software from Adobe itself.

Edit 2:

Adobe has quite some extensive documentation on their API and docs on their Acrobat.com services.
Their Acrobat products are in use by a lot of vendors, even the affordable ones, to provide PDF support.

Edit 1:

Downvoters: it is for two reasons I mentioned Arguably in my original answer.
First of all just stating best without adding more criteria will always get a subjective answer.
Second: Adobe is the inventor of PDF, and the PDF support of their software is great. I know there are drawbacks of Adobe software too, but the question was the 'best', which I interpreted as the best PDF support.

There is an on-line PDF compressor that I heard is giving good results.
It should not be too hard to wrap that in Delphi for occasional use.
