The one is the one that does not destroy the page index or the produce the false colors of embedded pictures comparing to the applications under $5.

I was looking for an application that can reduce the size of my curriculum vitae in PDF format because the website where I wanted to upload it didn't accept pdf file that exceed 200 k.o.

I downloaded and tried PDF Shrink along with two other application : PdfCompress and PDF Squeezer and here're the results :

PdfCompress : 127 ko
PDF Squeezer : 131 ko
PDF Shrink : 123 ko

PDF Shrink did the best work. The only problem with this application is that it's not very user-friendly comparing to the two other application, you need to tweak with it a little while before mastering it. Not to mention that it is overpriced.

It's a very useful tool that I'd buy when it is on sale on MacUpdate.

I disagree with some of the previous comments about ease of use and interface. The interface looks very nice, I didn't find anything complicated about the setup whatsoever. There was an option for dropping the file here for emailing, here for iPhone and iPad use, here for web, etc. and I used those to great success.
I literally installed the software, opened it, dropped my first PDF file onto it, PDF Shrink reduced it to a tenth of its former size, and I had my file -- all in about 3 minutes. It was super-easy, super-clear, and super-effective.
I haven't tried any of the customizing and have only used it once, but based on this experience I can only lament that I have but two thumbs to put up.

You can shrink any PDF yourself if you use Preview.app's "Save As" functionality and use Quartz Filter's "Reduce Size" setting.
So why would you need a tool like this? Simply because it gives you a much more fine-grained control over which aspects of the PDF are to be shrunk (reduced in quality), and by how much (Quartz's approach is brute-force, maximum compression).

PDF-Shrink uses an extremely ugly, decidedly Windows-ish interface that sometimes goes out of it's way to make the set-up process more difficult and technical than it needs to be.

However, after setting it up, the results are well worth it. We produce documentation that is to be read on-line and that usually contains a lot of imagery. Uncompressed the files are 80-100 MB. When we use Quartz for compression, the results are much smaller, but unacceptable.
Using PDF Shrink we control the quality of color images to be shrunk to 200 dpi, and greyscale to 150 dpi, which is well enough for both screen and casual prints. The file goes down in size to 5-8 MB, which is very, very nice.

Current version is 4.6.3

I compared this against several other apps/techniques for compressing ebooks and Shrink pretty consistently resulted in 10% smaller files. (72 dpi, low quality, for iPad)

Whether that is enough to justify $35 more than Quartz filters (free) or more basic app such as Squeeze ($2) is up to you.

As I've continued to try compressing different files that have I haven't been able to get good results any other way, I can say that PDF Shrink performs far better than the others on poor-quality scanned materials. For example, a particular 100MB black and white scanned file, no matter the settings, all other apps I tried compressed the file to a tiny ~8MB (even at 600dpi) none of which were practically readable.

PDF Shrink, at the highest quality settings, produced a 50MB that appears to be identical to the original. I have to say, though the interface is not attractive, the myriad of settings can really let you optimize the process to the situation.

If you aren't happy with the results of the less expensive alternatives, PDF Shrink is probably your best shot.

The reason why most PDF size reduction utilities available for the Mac suck big time is ...... that they are typically built using Apple's dated PDF Kit framework. PDF Kit does not support the compression methods CCITT Group 4 and JBIG2, even though these have been available in the PDF standard for many years already. The Group 4 and JBIG2 algorithms have been specifically developed for black-and-white documents, and so they are WAY more effective for this specific use case than Deflate (a general-purpose lossless algorithm which only yields a mediocre compression rate) and JPEG (a lossy algorithm, i.e. a method that trades in quality for the sake of a smaller file size, which works well for photographic images but not for scanned documents).

So in order to arrive at small file sizes, these tools will typically first reduce the image resolution, i.e. throw away image information, and then apply a low-quality JPEG compression, which makes things even worse by introducing visual artifacts.

It might be the case that PDF Shrink is in fact better than the competition, just because it is using its own PDF library instead of Apple'sā€¦

Tried to compress two files but it did not compress the PDF files. Same exact size, so this doesn't work. The features and concept are cool and easy who to use. You just drag and drop the PDF but the output file is not compressed so pointless. Too good to be true for the price. :-) Moved to trash.

PDF Shrink does the job and does it well.

But PDF compression should be built into the OS.

It turns out that it is:

Apple Discussion Board - http(colon-slash-slash)discussions(dot)apple(dot)com(slash)thread(dot)jspa?messageID=6109445&tstart=0

On the other hand, if you don't have time to tinker with filters, PDF Shrink does the job well. If we went the PDF Shrink route, I'd have to put PDF Shrink on four designer computers so we are building our own filters instead. Plus, core OS filters are likely to be compatible with future OS without updating costs.

The software is compatible with Mac OS X 10.4 and supports PDF Services, droplets and AppleScript.

Images make up a significant part of the size of typical PDF file. PDF Shrink can modify the resolution and compression level of the images to match different requirements. Fonts can also make PDFs larger than necessary so Shrink allows you to optionally remove embedded "base 14" fonts. Shrink can also delete unused elements such as metadata, thumbnails and duplicated data.

Protect your documents using PDF Shrink's new encryption feature. Prevent unauthorized access by adding a password or restrict use by selecting from several options including whether to allow changes, printing and content extraction. You can even set a different password to prevent unauthorized people from opening the PDF.

Need PDF optimized for a different use? The intuitive new wizard removes the jargon and unfamiliar terms from selecting different configurations to produce PDF optimized for different uses. Just tell the wizard how you plan to use your PDF and Shrink 4 picks the appropriate settings for you. Or use the Advanced mode to directly specify your settings.

PDF Shrink can be used in several different ways - drag-n-drop a PDF to the application icon or Dock, drag-n-drop to a setting, print through PDF Services, create a droplet or use AppleScript.

How much can PDF Shrink reduce the size of my PDF files? PDF files can be created by so many different applications that it is difficult to give one answer. PDF Shrink can reduce most types of PDF files by up to 10% to 90% of their original size.
