I tried it and unlike what other people said, when I tried it, it did definitely reduced the size of new file but I did found a major problem.
It removes clickable links from the pdf file ( and I used Text PDF ) and that could be a problem for some and not a problem at all for others.

For those who say the app does reduce file size: is it better or worse than reprinting the file in Foxit/Acrobat Reader with 'Smallest Size' option enabled?

"PDFCompressor Pro 5.2"
Today installed in Win8.1 without any trouble.
The first compression went fine:

Also a compression of a photo in PDF:

A very small difference between the original and compressed file(seen when switching between the two files):

But some other files were worse:

Test it, maybe I made a mistake.

Ootje, On their website: "Please check the Compress Quality and DPI value. If these two values are too low, the compressed PDF file could not keep the good quality. Try to turn the Compress Quality higher than 75% and set the DPI to 120. " Regards

PaulF, on the screendumps, the DPI is always 300 or higher for a scanned PDF.
With Txt-PDF the option is not active.

Ootje, I don't think you made a mistake Ootje..Downloaded, installed and registered CompressorPro successfully.
I set up PDFCompressor at High Quality with a 120 DPI (seeing as you cannot adjust it), selected both the file from and to go where. 35.9mb >21.7mb...ok good I thought...thot very wrong..it's a text PDF with schematics and it destroyed the schematics.
Next I tried with FreeCompressor, which I have used before...medium quality, not high quality, with a 150dpi (yes it's adjustable) ...took a bit longer to compress but 35.9mb > 18.3mb AND it did not destroy the schematics.
If PDF CompressorPro allowed for DPI adjustment then maybe, but for now it's a flop!

Just performed a quick test and the results were not impressive.
A4 size B&W drawing scanned at 400 dpi.
Original filesize: 116,900
PDF Compressor filesize: 1,679,888 - 14 times bigger!
pdfcompressor.com website: 31,363 - 73% smaller
All files look good - differences in file quality are negligible, even when zooming in.
Perhaps PDF Compressor Pro is good for some kinds of PDFs, but definitely not this one. For now I'll stick with free online compression.

Too few options means that colour pdf with photos - even at 90% setting - come out with an unacceptable quality.

Conny, You could set a higher DPI value to see if the output quality changes.

Alex, DPI in mine, and seems most others, is non adjustable off the 120 DPI mark...yes I adjusted for higher quality

I am very sorry but this piece of software is absolutely useless. In text mode the output file is bigger than the input file even if you set up the slider to smallest size /poorest quality/. It is not worth a penny!

Stoicho, There is a thing to press at the bottom `Why is the compressed file not smaller?'
It then tells you that with text files this happens, instead compress scanned files!
Like saying `you don't like the wine, try the whisky' but there isn't any, you only have wine!
Regarding emails, very useful indeed to be able to SEND an email with a compressed file, but someone at the other end who receives it has to decompress it! How?

Zen , Sorry Zen but if there is no whiskey, there may be beer...and in that case you don't have just wine.
It destroyed schematics in a PDF I had...I think most PDF viewer's can read the file..I tried the built in Edge viewer as well as Adobe, and both read exact same mess, both local and sent.

Stoicho,
From what you said it looks like the uncompressed file is worst than the original file.

Its good for emailing PDF files

Anwar, As long as the recipient has the programme. Otherwise how can he decompress it?

I have used this several times in the past and it simply does not do what they say it can. Quite often the 'compressed' file is actually the same or larger and the quality is very bad, but they want for $29.95 for it!
I find "Free PDF Compressor" from freepdfcompressor.com does a much better job - and umm.... for free.

User101, try setting the PDF Type as "Text PDF" :)
