Notice: This PDF compressor uses exclusive engine designed by our software team. It doesn't work like file compressor software such as WinZip, WinRAR or 7-Zip. It reduces PDF file size by reducing the images' quality in PDF file. This will significantly reduce file size of high-DPI scanned PDF files. Smaller PDF file is more easier to be uploaded online or sent by email.
