Compress PDF files quickly and easily
The PDF format is ideal for presenting and sharing complex texts, diagrams, graphics and forms. However, PDF files are therefore often very extensive, which in turn is actually a knockout criterion for sharing.
With PDF-compress you can optimize your PDF files so that they do not take up more storage space than absolutely necessary. Depending on the structure and content of the PDF document, compression rates of up to 95% can be achieved. In a test with over 1,000 randomly selected PDF files from different sources, an average compression rate of almost 50% was achieved.
PDF-compress uses different approaches for compression. For example, images contained in the document can be compressed losslessly, special optimization technology (MRC) can be applied, and blank pages and annotations can be removed from the PDF structure. Optionally, the image quality can also be reduced in several stages and an optimization for the display on the web can be carried out.

Reviews for PDF-compress
There is no other desktop application with the quality and the compression ratio like this one (Ascomp Pdf-Compress)… and I have tested a lot of software.
Only online is it possible to find similar features.
5 stars!
So far, so good.
[Aside… I wouldn’t usually give a “version 1.0” product more than a passing glance, because as somebody who has developed certification courseware for a lot of software houses to go alongside their new releases (up to, yes, the very *** of Hell), I well know that release candidates are more often shaky early-beta-versions (or even alpha-versions that should be under lock-and-key in the lab – Windows 5 aka 2000, I am looking at you) and at this stage I haven’t got the time or nerves to be an unwitting tester.]
…As I was saying, I have another Ascomp product (TextR) which I am most pleased with, so I had few qualms about trying this out. I am satisfied with this offering and shall certainly keep it and put it to good use. I won’t go into the ins and outs of the features it offers the user (I’ve gasbagged enough as it is), so suffice to say, after installing (no problems surfaced), I immediately tested it on a 136 MB ICAO pdf, full of drawings and photos of aircraft and it came out at a most creditable 54 MB. Any reduction in onscreen quality was indiscernible, only if I magnified to an excessive degree, like 400+, so fine lines in serif face showed evidence of reduced quality.
What’s more, the conversion duration for this file was a startling 8 seconds (so quick that I was more than a little sceptical until I located the compressed pdf, saw its size and then opened it and scrutinised it for quality.)
I then tested a number of other pdfs of various sizes and was delivered similar pleasing reductions in file size. These also went by very quickly. I should say, on two of the large files that I tested (not the aforementioned first test), the interface hung on completion (after indicating “conversion complete”) and I had to kill the process, although on each occasion, the file had been compressed and was waiting for me in its destination folder.
There are a number of settings for quality of output, including the preserving of image quality, along with maximum desired image dpi; and settings for as output folder, naming preferences, and others which you can explore. The interface is clean and nice to work with, and, though on the darkish side, it is a pleasant ultramarine (on my orangey screen), and not, thankfully, the ubiquitous dreary black.
Nicely done, Ascomp! Suggestion for next version: it would be handy to have a small dialogue after each compression to show the before and after sizes immediately, otherwise one discovers this only at the moment of opening the relevant destination folder..
