Here are 4 free PDF compressor websites.
These websites are really helpful to shrink the size of your large PDF files to save the hard disk space. Without creating any zip archive, you can compress your PDF files. Most of these websites help to greatly reduce (more than 60 percent) your PDF files. However, do note that compression process also depends on the number of images available in your PDF files. If your file has multiple images or scanned text, compression level will be higher. Let’s have a look at these free PDF compressor websites.
