Compress PDF files for publishing on web pages, sharing in social networks or sending by email.  Unlike other services this tool doesn't change the DPI, thus keeping your documents printable and zoomable. 

Select PDF files from your computer or drag them to the drop area.  You can upload up to 20 files at a time.  Wait until the PDF compression is completed.  Download each file individually, or you can download all of your files at once in a ZIP archive.
