    "So, I handle a TON of PDF files every day, and I'm always looking to keep my file sizes kind of low, if possible. I thought it was pretty cool that Online2pdf could maybe provide smaller files while they're converting my files to PDF (for free, I might add), but let me tell you, they did NOT do what they said they would. I tried two different converters, but theirs was twice the size of the other one! How am I expected to keep my hard drive from maxing out if that's going to happen? Will not be using their services again!"

    "Having a handle on my PDFs is really important to me because I handle so many of them on a daily basis. I usually try to keep file sizes as small as possible to save space, but I had some trouble with available resources for reducing PDF file size. The site I love PDF was the answer and then some. They have SO many utilities that can help with your PDF files, and one of those is reducing file size. It was a lifesaver!"

    "This was pretty decent at reducing PDF size, but it wasn't perfect. The program can do quite a bit to help reduce the size of a PDF, but it can't really do a great amount. You can compromise on image quality for size and change some of the options for compression, but you can't do too much other than that. It works, sure, but it's not perfect."

    "Nitro Pro is a service that replaces Adobe Acrobat. Unfortunately, it is not a free alternative and is very expensive. In addition, they don't seem to offer a way to reduce PDF file sizes, making this a worthless investment for such a task."
