With this freeware, you are able to set the compression level to generate PDF files of smallest size.
Editor's review of Free PDF Compressor Despite being a bit of a resource hog itself, this application seriously reduces the size of your PDF files. Free PDF Compressor offers a straightforward interface with only a few standard buttons for selecting, compressing, and decompressing PDF files. The program lets you choose from two compression algorithms and four compression levels. Though we found the RunLength much faster than the Flate algorithm, Free PDF Compressor did indeed noticeably shrink PDF files in testing using either option, with no change in the quality of the compressed PDF files. However, the program uses 40MB to 50MB of memory and significantly slowed down our system during the compression process. This single-purpose application is an easy-to-use, freeware option for shrinking PDF files, but it may cost you some speed when it's at work.
