    Hi,

    we are interested in trying how your pdfcompress (http://www.verypdf.com/wordpress/201209/how-to-compress-pdf-by-command-line-31834.html) works under commend line. However we got an error when trying to open the tiny sized output.pdf: "Insufficient data for an image". Is there a way we can make a full test that cold get us the final file size and the output.pdf to view the quality of the result?

    We are a large public company of about 20,000 employee, we will definite purchase a license if the result is good.

    Thank you!
