While this is working, it modifies the positions in the pdfs. PdfCompress doesn't. (

Nice app. Would be 5 stars if it had 2 more features: drag and drop and a way to set the default quality of the compression without going into each individual document. Keep the updates coming, guys, you got a good thing going here!

Very efficient and easy to operate! What I need to do is drag the PDF to the window and choose the right conversion quality! Indispensable for me to send small size PDF by e-mail! It did help me at work!
