Quick, Easy, Good Value!

Converting TIFF files to PDF left me with a 12MB file that was too big to email. The “reduce size” filter in Preview left the document unreadable. I value my time, and I do not trust some of the “free” PDF Squeeze utilities on the internet to maintain my privacy.

At $2.99, PDFOptim did a great, quick job of compressing my file. The interface was intuitive, and it allowed me to compare the loss of quality for greater levels of compression. Since the download is small, and the interface easy to understand, I had my file reduced from 12MB to 2.2MB in about 3 minues.

I guess some people expect miracles for a $2.99 app, but I remember the days when this functionality was only available in the $149 Acrobat Standard application, and it was more difficult to use.

Does exactly what was needed!

Kept having problems trying to figure out how to reduce pdf file sizes. Found this app and decided to try it. Did exactly what I needed! Could have saved me lost time searching and searching. Just a couple of clicks and it resizes the file. Could now email without any size issues. When you reduce a file, it does reduce the quality a bit, but this app kept the quality at a decent level and was still easy.

It's worth $1 if you don't have other options

I bought this to compare it to Adobe Acrobat's (Pro v8) built-in File Reducer / Optimizer since I have a large number of scannerd / OCRd PDFs I'd like to optimize. I was not able to tweak the settings in PDFOptim to result in the same size reduction while maintaining a similar quality as Acrobat does on its default setting. I am sure that newer versions of Acrobat will be doing an even better job. If you happen to have access to Acrobat, I would recommend using it for file reduction.
